I bought $1k of the Top 10 Cryptos on January 1st, 2018 (Oct Update - Month 34)

EXPERIMENT - Tracking Top 10 Cryptos of 2018 - Month Thirty-Four - Down -74%
See the full blog post with all the tables here.
tl;dr
  • I'll give the first one to find the four hidden cultural references some moons.
  • What's this all about? I purchased $100 of each of Top Ten Cryptos in Jan. 2018, haven't sold or traded. Did the same in 2019 and 2020. Learn more about the history and rules of the Experiments here.
  • October - BTC and Litecoin had a very good month and crypto as a whole did much better than traditional markets.
  • Overall since Jan. 2018 - Bitcoin still far ahead. And, for the first time since I started this experiment back in Jan. 2018, I'm happy to report: BITCOIN HAS BROKEN EVEN!!!
  • Combining all three three years, Top Ten cryptos is tied with the S&P if I'd taken a similar approach.

Month Thirty Four – Down 74%

2018 Top Ten Summary for October
After an all-red September, it’s nice to see a bit of green this month. Thanks mainly to Bitcoin, the 2018 Top Ten Portfolio finished October with modest gains overall.
But, STOP THE PRESS, what is that!??! Green in the “Total % Change” column!?!? Yes indeed: for the first time in 34 monthly updates, I’m happy to announce that BTC ended October worth more than the price I paid for it on the 31st of December, 2017. Although only up +4% overall, it’s been a long road: this small 2018 Top Ten victory is to be celebrated.

Question of the month:

In October, this global payment service announced it will support cryptocurrency buying, selling, and shopping through its platform.

A) Paypal
B) Square
C) Stripe
D) Alipay

Ranking and October Winners and Losers

Rank of 2018 Portfolio - 40% of cryptos are drop outs
Not much movement this month, a bit strange for the 2018 Top Ten Portfolio. Only three cryptos shifted positions in October: NEM’s Top Twenty hopes seem to be fading fast (it dropped from #22 to #24); XLM picked up one spot (#18 to #17); and, much to the relief of long time crypto-ers with a soft spot for the silver to BTC’s gold, Litecoin was able to stop its freefall, rebounding back into the Top Ten nicely, picking up four spots (#12 to #8). Welcome back LTC.
Drop outs: After thirty-four months of this experiment 40% of the cryptos that started 2018 in the Top Ten have dropped out. NEM, Dash, IOTA, and Stellar have been replaced by Binance Coin, Tether, LINK, and most recently, DOT.
October Winners – For the second month in a row, this month’s W goes to Bitcoin, up +25% for the month. Litecoin finishes the month in second place, up 17% and climbing back into the Top Ten.
October Losers – For the second month in a row, this month’s L goes to NEM, down -16%. IOTA finished down -11%, the second worst performer of the month.
For the overly competitive nerds, below is a tally of the winners of the first 34 months of the 2018 Top Ten Crypto Index Fund Experiment. Bitcoin still has the most monthly wins (9) and Cardano in second place with 6 monthly wins. With another poor performance in October, NEM now has 8 monthly losses.
Every crypto has at least one monthly win and Bitcoin is unique as the only cryptocurrency that hasn’t lost a month yet since January 2018.
Ws and Ls - One coin to rule them all

Overall update – BTC far ahead and breaks even, ETH in distant second place. Dash in last place.

So here we are: point break even. On the 31st of December, 2017, I bought $100 worth of BTC (0.008) at $13,170. Nearly three years later that same 0.008 is worth $13,665. Although only 4%, it’s a symbolic victory and one that’s been a long time coming. The initial investment of $100 thirty-three months ago is now worth about $83. A distant second place, Ethereum is down -45% since January 2018.
At this point in the 2018 Top Ten Experiment, Dash is at the bottom. It has lost -93%. The initial $100 invested in Dash 34 months ago is now worth $6.52.
The 2018 Portfolio welcomed LTC back Top Ten in October. September 2020 was the first time since I started the experiment back in January 2018 that Litecoin had fallen out of the Top Ten.

Total Market Cap for the entire cryptocurrency sector:

Total market cap - back over the $400B mark for the first time in over 2.5 years
The crypto market gained about $50B in finished October over the psychologically important $400B mark, a level we haven’t seen since the end of April 2018.

Bitcoin dominance:

BitDom - growing
After a few months of dipping, BitDom shot back up to 63.1% in October. A big move, but for context, it was up over 68% earlier in 2020.
For even more context: since the beginning of the experiment, the range of Bitcoin dominance has been quite wide: we saw a high of 70% BitDom in September 2019 and a low of 33% BitDom in February 2018.

Overall return on $1,000 investment since January 1st, 2018:

2018 Top Ten ROI
The 2018 Top Ten Portfolio gained about $25 bucks in October. Despite BTC breaking even, the portfolio overall is still struggling: if I cashed out today, the $1000 initial investment would return about $264, down -74% from January 2018.
Down -74% sounds bad (and it is), but the overall direction lately has been encouraging and a nice break from the negative eighties. Here’s a look at the ROI over the life of the experiment, month by month, for some context:

2018 Top Ten Monthly ROI - Red, red, red
The absolute bottom was -88% back in January 2019.
So the Top Ten Cryptos of 2018 are down -76%. What about the 2019 and 2020 Top Tens? Let’s take a look:
So overall? Taking the three portfolios together, here’s the bottom bottom bottom line:
After a $3000 investment in the 2018, 2019, and 2020 Top Ten Cryptocurrencies, my combined portfolios are worth $‭3,537‬ ($264+ $1,660 +$1,613).
That’s up about +18% for the three combined portfolios, compared to +11% last month.
Here’s a table to help visualize:
Combined 2018, 2019, 2020 ROI
That’s a +18% (actually +17.9%) gain by investing $1k on whichever cryptos happened to be in the Top Ten on January 1st for three straight years.
But surely you’d do better if you went all in on one crypto, right?
Depends on your choice. Let’s take a look:
Three year club: BTC and ETH tied
Only five cryptos have started in the Top Ten for all three years: BTC, ETH, XRP, BCH, and LTC. Knowing what we know now, which one would have been best to go all in on?
As of this month, it’s basically a tie between BTC and ETH. Both are up +121%, (although BTC is technically $21 ahead of ETH).
So: with $3,000 USD, dropped in $1k chunks on January 1st three times in a row since New Year’s Day 2018, you would be up +121%, by going all in on either BTC or ETH.
The worst choice? At this point in the experiment, that would be XRP, down -32%.

Comparison to S&P 500:

I’m also tracking the S&P 500 as part of the experiment to have a comparison point with other popular investments options. The S&P 500 Index continued its fall from an all time high in August. It ended October up +22% since January 2018.

Monthly S&P since January 2018
The initial $1k investment into crypto on January 1st, 2018 would have been worth about $1220 had it been redirected to the S&P.
But what if I took the same invest-$1,000-on-January-1st-of-each-year approach with the S&P 500 that I’ve been documenting through the Top Ten Crypto Experiments? Here are the numbers:
  • $1000 investment in S&P 500 on January 1st, 2018 = $1220 today
  • $1000 investment in S&P 500 on January 1st, 2019 = $1300 today
  • $1000 investment in S&P 500 on January 1st, 2020 = $1010 today
Taken together, here’s the bottom bottom bottom line for a similar approach with the S&P:
After three $1,000 investments into an S&P 500 index fund in January 2018, 2019, and 2020, my portfolio would be worth $3,530.
That is up +17.6% since January 2018. Compared to a +17.9% gain of the combined Top Ten Crypto Experiment Portfolios. You can compare against five individual coins (BTC, ETH, XRP, BCH, and LTC) by using the table above if you want.
Gentlemen and lady (hello lady, I see you back there) we have a tie.
Well, not quite a tie, crypto is up .3% so crypto gets the win:
Three year S&P vs. Top Ten Crypto Experiments Combined ROI
That’s seven monthly victories for the S&P vs. three monthly victories for crypto. The largest gap so far was a 22% difference in favor of the S&P in June.

Conclusion:

October saw a bit of divergence between crypto and the S&P: crypto up, S&P down. That separation is nice to see when it often seems that crypto moves in tandem with traditional markets. Two more months left in the year. What more will 2020 throw at us? And how will crypto and traditional markets respond?
Thanks for reading and for supporting the experiment. I hope you’ve found it helpful. I continue to be committed to seeing this process through and reporting along the way. Feel free to reach out with any questions and stay tuned for progress reports. Keep an eye out for my parallel projects where I repeat the experiment twice, purchasing another $1000 ($100 each) of two new sets of Top Ten cryptos as of January 1st, 2019 then again on January 1st, 2020.

And the Answer is…

A) Paypal
Paypal announced in October that it will allow customers to buy, sell, and hold Bitcoin and other cryptocurrencies. Customers will also be able to pay with crypto at 26 million merchants on its network starting in early 2021.

[Serious] How to deal with Crypto Tax 2020?

First of all, please upvote for visibility + more opinions - this concerns all of us. Also, if you're stupid enough to think you'll get away with avoiding tax's despite KYC'ing to Coinbase & Binance don't bother commenting. News flash! you're gonna end up paying that tax in the long run + huge fines eating into your gains (or even putting you into debt).

Anyways... I started investing in 2017. As a noob I did what most people did, chased multiple shitcoins, bought and sold various different pumps getting wrecked along the way. Then towards the end of the year, my portfolio increased significantly... but I DIDN'T sell - so I didn't "crystalise" any gainz. (I sold a couple hundred here and there during hard financial times, but I'm guessing nothing close to the free capital gains allowance).
Fast forward just over 2 years, since then I've been buying BTC/ETH/XMR on a consistent basis. It's getting to the point where if I were to sell enough of my stack, I'd owe tax as it'd be over the "allowed" CGT threshold.
That leads me to my question... how the fuck are you supposed to calculate capital gains tax when it comes to crypto? For the past 3 years I've traded in and out of alt-coins on multiple exchanges (some of which don't even exist anymore). It would be easy if it was just FIAT IN vs FIAT OUT, but the fact that CRYPTO to CRYPTO is considered taxable just makes it a nightmare! On top of that I did some freelance work (paid in BTC) which adds to the complexity.
Take another example of what confuses me: Say I bought 1BTC on Coinbase in 2017, then 1BTC on Kraken in 2018, then 0.5BTC on Coinbase again in 2019, and hold them all in the same wallet. Then if I were to sell 0.5BTC in 2020, what Bitcoin was actually sold? Half of the 1 BTC bought in 2017? Is it FIFO?
I genuinely don't know where to start and need help. I don't want to be in a shitty situation (for example some massive 2017-esque bull run happens just before the end of the tax year and I decide to cash out and have 3 days to sort shit out). I want to be prepared.

I've come across services such as https://www.cointracker.io/ /https://bitcoin.tax/ etc but feel really hesitant to give quasi-unknown companies full read access to my wallet addresses, portfolio amount, personal email address etc. Privacy is key in the crypto space and I don't want another attack vector especially after seeing much more established companies such as Ledger fucking up (idiots) and losing my personal data.
What do I do? I've even thought of selling EVERYTHING to FIAT and immediately buying it all back and taking whatever fine comes my way on the chin just so I can clearly track crypto transactions and not have to stress about it.
If anyone has experience with crypto tax's please share any information that may be valuable to me/all the many others that are in the same situation as me.

TL;DR: Bought loads of Bitcoin and Shitcoins throughout the past 3 years, finally starting to total up to an amount that'd be taxable if I sold a chunk - dafuq do I do regarding Taxes?

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

'''
First of all, please upvote for visibility + more opinions - this concerns all of us. Also, if you're stupid enough to think you'll get away with avoiding tax's despite KYC'ing to Coinbase & Binance don't bother commenting. News flash! you're gonna end up paying that tax in the long run + huge fines eating into your gains (or even putting you into debt).

Anyways... I started investing in 2017. As a noob I did what most people did, chased multiple shitcoins, bought and sold various different pumps getting wrecked along the way. Then towards the end of the year, my portfolio increased significantly... but I DIDN'T sell - so I didn't "crystalise" any gainz. (I sold a couple hundred here and there during hard financial times, but I'm guessing nothing close to the free capital gains allowance).
Fast forward just over 2 years, since then I've been buying BTC/ETH/XMR on a consistent basis. It's getting to the point where if I were to sell enough of my stack, I'd owe tax as it'd be over the "allowed" CGT threshold.
That leads me to my question... how the fuck are you supposed to calculate capital gains tax when it comes to crypto? For the past 3 years I've traded in and out of alt-coins on multiple exchanges (some of which don't even exist anymore). It would be easy if it was just FIAT IN vs FIAT OUT, but the fact that CRYPTO to CRYPTO is considered taxable just makes it a nightmare! On top of that I did some freelance work (paid in BTC) which adds to the complexity.
Take another example of what confuses me: Say I bought 1BTC on Coinbase in 2017, then 1BTC on Kraken in 2018, then 0.5BTC on Coinbase again in 2019, and hold them all in the same wallet. Then if I were to sell 0.5BTC in 2020, what Bitcoin was actually sold? Half of the 1 BTC bought in 2017? Is it FIFO?
I genuinely don't know where to start and need help. I don't want to be in a shitty situation (for example some massive 2017-esque bull run happens just before the end of the tax year and I decide to cash out and have 3 days to sort shit out). I want to be prepared.

I've come across services such as [[link]3 /[[link]4 etc but feel really hesitant to give quasi-unknown companies full read access to my wallet addresses, portfolio amount, personal email address etc. Privacy is key in the crypto space and I don't want another attack vector especially after seeing much more established companies such as Ledger fucking up (idiots) and losing my personal data.
What do I do? I've even thought of selling EVERYTHING to FIAT and immediately buying it all back and taking whatever fine comes my way on the chin just so I can clearly track crypto transactions and not have to stress about it.
If anyone has experience with crypto tax's please share any information that may be valuable to me/all the many others that are in the same situation as me.

TL;DR: Bought loads of Bitcoin and Shitcoins throughout the past 3 years, finally starting to total up to an amount that'd be taxable if I sold a chunk - dafuq do I do regarding Taxes?

TkeyNet: What’s new?

TkeyNet: What’s new?

https://i.redd.it/zyuf3vxvvdp51.gif
“The TkeyNet development team is surprising to us” — recently such a quote came from our lips. Why would that be?

TkeyNet: Instant transactions

Now transactions in the TkeyNet network are instant. You won’t even notice how the TKEY delivers to the recipient. For example, when you send a payment from card to card, and after a few seconds, the money is in the recipient’s possession. Despite the fast speed of transactions, the system has not only preserved its security properties but also strengthened them and still works on the blockchain.
“The chain of information a store on every computer in the network. The addition of information occurs by using cryptographic functions, allowing you to identify the information for any period. When a new data block adds to the TkeyNet network, the integrity of all previous information confirm by the entire TkeyNet, and each node checks its integrity.”

Financial marketplace


https://preview.redd.it/4j6y85zxvdp51.png?width=1920&format=png&auto=webp&s=1ef221053e4e90b08a9f67e6eef220b74bc94b0f
In early September, we completed work on one of the main functions of the system: “The Financial Module Of The Marketplace.”

What is it for, and how does the “Financial Marketplace module” work?

TkeyNet combines various assets in a single system, creating instant access to liquidity. Digital exchanges connect to TkeyNet and provide assets for exchange: BTC, USDT, ETH, and others. For example, Kraken connects to TkeyNet and provides digital assets: ETH, ETC. Binance: USD, BTC. Bitfinex: USDT, EOS, etc. Exchanges can provide any assets that trade on their platforms.
The blockchain acts as a Registrar of financial transactions. Accounts, balances, and orders store in a distributed registry TkeyNet, and copies of data to distribute across network TkeyNet nodes. Payment routing is implemented in the TkeyNet system, which allows you to track not only balances but also distribute transactions without the participation of any party.
The user, in turn, has quick access to transactions with digital currencies, regardless of the blockchain used: Bitcoin, Ethereum, EOS, or any other, transactions are recorded in TkeyNet, and transactions are processed instantly.
“The task of the platform is to automate the interaction of the parties and ensure the convenience of performing operations. — This is the core element of a trusted environment.”
In addition to digital assets, the “Financial Marketplace module” includes working with Fiat currencies, stocks, bonds, as well as raw materials: oil, gas, diamonds, etc. — This means that payment systems, banks, currency exchanges, commodity exchanges, and other financial market participants, are also connected to the TkeyNet blockchain.

Payments between companies in a few seconds

https://preview.redd.it/v84fizszvdp51.png?width=1920&format=png&auto=webp&s=e501b06661b2a960fe75abe07a1aba5177db620d
Companies can make payments in seconds, not days. TkeyNet can seriously mitigate the adverse risks of extraterritorial sanctions against the financial system of the countries if such follow. Also, the ability to conduct internal and cross-border transfers through an independent financial channel directly to the counterparty at high-speed is beneficial to business and the state from any point of view.
Each user will be able to make quick transfers to counterparty wallets, exchange digital currency for another or fiat money at the current exchange rate.

What else is interesting? — Applications

Developers can connect to TkeyNet and get access to a large-scale pool of liquidity: digital currencies, stocks, precious metals, etc.
This solution not only reduces development costs but also allows you to get access to the best prices and fast exchanges. You can create any financial application, regardless of the market usage: a cryptocurrency, or financial markets.
Developers can create a digital Bank or exchange, fast connect the app, and TkeyNet using the API.
“By working with partners around the world, we can significantly increase our market share in this business, providing our partners with ready-made tools without risks.”
And also regardless of the applications that will be created by partner developers. The company will provide its interfaces that will provide access to various types of assets — digital currencies: BTC, USDT, ETH, etc.; Fiat currencies: euros, dollars, pounds, etc.; securities and commodity assets.

https://preview.redd.it/23whmnm1wdp51.png?width=679&format=png&auto=webp&s=52bf10bf43268f835cff981a110d41528b838a89
Anywhere in the world, at any time, the system user will have access to the desired currency without having to exchange one for another. Also, when implementing the application for NFC payments, it will become even easier to use the system. However, even with the availability of several types of currencies, such as the pound, dollar, and euro, it is easy to make payments abroad.
“According to the World Bank, more than 1.7 billion adults are still not covered by banking services, but two-thirds of them have a mobile phone that can help them access financial services. — This tells us one thing: the traditional banking approach is exceptionally inefficient. Lack of infrastructure: a network of ATMs, fees and deposits, a network of cashiers, and internal money transfer programs are just some named obstacles to creating a real banking experience.”
Imagine that in one app you have access to Apple shares, Tesla shares, gold, precious metals, rubles, dollars, and even oil if you want. TkeyNet — makes this possible.
TkeyNet is an industrial solution designed for companies and users at the same time. Since payments in the system are very fast, a person can store and send money in any asset they want. This flexibility creates an open market, which is necessary at present.

Postscript

TkeyNet back-end — completed. Currently, we are actively working on the front-end side. Regardless of working on the front-end side, the TkeyNet system is tested on an ongoing basis.

Crypto Banking Wars: Can BlockFi & Celsius Disrupt Banking?

Crypto Banking Wars: Can BlockFi & Celsius Disrupt Banking?
These crypto lending & borrowing services found early traction. Are they capable of bundling more financial services and winning the broader consumer finance market?
https://reddit.com/link/icps9l/video/98kl1y596zh51/player
This is the third part of Crypto Banking Wars — a new series that examines what crypto-native company is most likely to become the bank of the future. Who is best positioned to reach mainstream adoption in consumer finance?
While crypto allows the world to get rid of banks, a bank will still very much be necessary for this very powerful technology to reach the masses. As we laid out in our previous series, Crypto-Powered, we believe a crypto-native company will ultimately become the bank of the future. We’re confident Genesis Block will have a seat at that table, but we aren’t the only game in town.
In the first post of this series, we did an analysis of big crypto exchanges like Coinbase & Binance. In our second episode, we looked at the world of non-custodial wallets.
Today we’re analyzing crypto lending & borrowing services. The Earn and Borrow use-case covers a lot of what traditional banks deliver today. This category of companies is a threat worth analyzing. As we look at this market, we’ll mostly be focused on custodial, centralized products like BlockFi, Nexo, and Celsius.
Many of these companies found early traction among crypto users. Are they capable of bundling more financial services and winning the broader consumer finance market? Let’s find out.

Institutional Borrowers

Because speculation and trading remains one of the most popular use-cases of crypto, a new crypto sub-industry around credit has emerged. Much of the borrowing demand has been driven by institutional needs.
For example, a Bitcoin mining company might need to borrow fiat to pay for operational costs (salaries, electricity). Or a crypto company might need to borrow USD to pay for engineering salaries. Or a crypto hedge fund needs to borrow for leverage or to take a specific market position. While all of these companies have sufficient crypto to cover the costs, they might not want to sell it — either for tax or speculative reasons (they may believe these crypto assets will appreciate, as with most in the industry).
Instead of selling their crypto, these companies can use their crypto as collateral for loans. For example, they can provide $1.5M in Bitcoin as collateral, and borrow $1M. Given the collateralization happening, the underwriting process becomes straightforward. Companies all around the world can participate — language and cultural barriers are removed.

https://preview.redd.it/z9pby83d6zh51.png?width=600&format=png&auto=webp&s=54bf425215c3ed6d5ff0ca7dbe571e735b994613
The leader (and one of our partners) in this space is Genesis Capital. While they are always the counterparty for both lenders and borrowers, they are effectively a broker. They are at the center of the institutional crypto lending & borrowing markets. Their total active loans as of March 2020 was $649M. That number shot up to $1.42B in active loans as of June 2020. The growth of this entire market segment is impressive and it’s what is driving this opportunity for consumers downstream.

Consumer Products

While most of the borrowing demand comes from institutional players, there is a growing desire from consumers to participate on the lend/supply side of the market. Crypto consumers would love to be able to deposit their assets with a service and watch it grow. Why let crypto assets sit on an exchange or in cold storage when it can be earning interest?
A number of consumer-facing products have emerged in the last few years to make this happen. While they also allow users to borrow (always with collateral), most of the consumer attraction is around growing their crypto, even while they sleep. Earning interest. These products usually partner with institutional players like Genesis Capital to match the deposits with borrowing demand. And it’s exactly part of our strategy as well, beyond leveraging DeFi (decentralized finance protocols).
A few of the most popular consumer services in this category include BlockFi, Nexo, and Celsius.

https://preview.redd.it/vptig5mg6zh51.png?width=1051&format=png&auto=webp&s=b5fdc241cb9b6f5b495173667619f8d2c93371ca

BlockFi

BlockFi (Crunchbase) is the leader in this category (at least in the West). They are well-capitalized. In August 2019, they raised $18.3M in their Series A. In Feb 2020, they raised $30M in their Series B. In that same time period, they went from $250M in assets under management to $650M. In a recent blog post, they announced that they saw a 100% revenue increase in Q2 and that they were on track to do $50M in revenue this year. Their growth is impressive.
BlockFi did not do an ICO, unlike Celsius, Nexo, Salt, and Cred. BlockFi has a lot of institutional backing so it is perceived as the most reputable in the space. BlockFi started with borrowing — allowing users to leverage their crypto as collateral and taking out a loan against it. They later got into Earning — allowing users to deposit assets and earn interest on it. They recently expanded their service to “exchange” functionality and say they are coming out with a credit card later this year.

https://preview.redd.it/byv2tbui6zh51.png?width=800&format=png&auto=webp&s=bac080dcfc85e89574c30dfb396db0b537d46706
Security Woes
It’s incredible that BlockFi has been able to see such strong growth despite their numerous product and security woes. A few months ago, their systems were compromised. A hacker was able to access confidential data, such as names, dates of birth, postal addresses, and activity histories. While no funds were lost, this was a massive embarrassment and caused reputational damage.

https://preview.redd.it/lwmxbz5l6zh51.png?width=606&format=png&auto=webp&s=ebd8e6e5c31c56da055824254b35b218b49f80e0
Unrelated to that massive security breach and earlier in the year, a user discovered a major bug that allowed him to send the same funds to himself over and over again, ultimately accumulating more than a million dollars in his BlockFi account. BlockFi fortunately caught him just before withdrawal.
Poor Product Execution
Beyond their poor security — which they are now trying to get serious about — their products are notoriously buggy and hard-to-use. I borrowed from them a year ago and used their interest account product until very recently. I have first-hand experience of how painful it is. But don’t take my word for it… here are just a few tweets from customers just recently.

https://preview.redd.it/wcqu3icn6zh51.png?width=1055&format=png&auto=webp&s=870e2f06a6ec377a87e5d6d1f24579a901de66b5
For a while, their interest-earning product had a completely different authentication system than their loan product (users had two sets of usernames/passwords). Many people have had issues with withdrawals. The app is constantly logging people out, blank screens, ugly error messages. Emails with verification codes are sometimes delayed by hours (or days). I do wonder if their entire app has been outsourced. The sloppiness shines through.
Not only is their product buggy and UX confusing, but their branding & design is quite weak. To the left is a t-shirt they once sent me. It looks like they just found a bunch of quirky fonts, added their name, and slapped it on a t-shirt.

https://preview.redd.it/mi6yeppp6zh51.png?width=600&format=png&auto=webp&s=fd4cd8201ad0d5bc667498096388377895b72953
Culture
To the innocent bystander, many of these issues seem totally fixable. They could hire an amazing design agency to completely revamp their product or brand. They could hire a mercenary group of engineers to fix their bugs, etc. While it could stop the bleeding for a time, it may not solve the underlying issues. Years of sloppy product execution represents something much more destructive. It represents a top-down mentality that shipping anything other than excellence is okay: product experience doesn’t matter; design doesn’t matter; craftsmanship doesn’t matter; strong execution doesn’t matter; precision doesn’t matter. That’s very different from our culture at Genesis Block.
This cancerous mentality rarely stays contained within product & engineering — this leaks to all parts of the organization. No design agency or consulting firm will fix some of the pernicious values of a company’s soul. These are deeper issues that only leadership can course-correct.
If BlockFi’s sloppiness were due to constant experimentation, iteration, shipping, or some “move fast and break things” hacker culture… like Binance… I would probably cut them more slack. But there is zero evidence of that. “Move fast and break things” is always scary when dealing with financial products. But in BlockFi’s case, when it’s more like “move slow and break things,” they are really playing with fire. Next time a massive security breach occurs, like what happened earlier this year, they may not be so lucky.
Institutional Focus
Based on who is on their team, their poor product execution shouldn’t be a surprise. Their team comes mostly from Wall Street, not the blockchain community (where our roots are). Most of BlockFi’s blockchain/crypto integration is very superficial. They take crypto assets as deposits, but they aren’t leveraging any of the exciting, low-level DeFi protocols like we are.
While their Wall Street heritage isn’t doing them any favors on the product/tech side, it’s served them very well on winning institutional clients. This is perhaps their greatest strength. BlockFi has a strong institutional business. They recently brought on Three Arrows Capital as a strategic investor — a crypto hedge fund who does a lot of borrowing. In that announcement, BlockFi’s founder said that bringing them on “aligns well with our focus on international expansion of our institutional services offering.” They also recently brought someone on who will lead business development in Asia among institutional clients.
BlockFi Wrap Up
There are certainly BlockFi features that overlap with Genesis Block’s offering. It’s possible that they are angling to become the bank of the future. However, they simply have not proven they are capable of designing, building, and launching world-class consumer products. They’ve constantly had issues around security and poor product execution. Their company account and their founder’s account seem to only tweet about Bitcoin. I don’t think they understand, appreciate, or value the power of DeFi. It’s unlikely they’ll be leveraging it any time soon. All of these reasons are why I don’t see them as a serious threat to Genesis Block.
However, because of their strong institutional offering, I hope that Genesis Block will ultimately have a very collaborative and productive partnership with them. Assuming they figure out their security woes, we could park some of our funds with BlockFi (just as we will with Genesis Capital and others). I think what’s likely to happen is that we’ll corner the consumer market and we’ll work closely with BlockFi on the institutional side.
I’ve been hard on BlockFi because I care. I think they have a great opportunity at helping elevate the entire industry in a positive way. But they have a lot of issues they need to work through. I really don’t want to see users lose millions of dollars in a security breach. It could set back the entire industry. But if they do things well… a rising tide lifts all boats.

Honorable Mentions

Celsius (ICO Drops) raised $50M in an ICO, and is led by serial entrepreneur Alex Mashinsky. I’ve met him, he’s a nice guy. Similar to Binance, their biggest Achilles heel could be their own token. There are also a lot of unanswered questions about where their deposits go. They don’t have a record of great transparency. They recently did a public crowdraise which is a little odd given their large ICO as well as their supposed $1B in deposits. Are they running out of money, as some suggest? Unclear. One of their biggest blindspots right now is that Mashinsky does not understand the power of DeFi. He is frequently openly criticizing it.
Nexo (ICO Drops) is another similar service. They are European-based, trying to launch their own card (though they’ve been saying this forever and they still haven’t shipped it), and have a history in the payments/fintech space. Because they haven’t penetrated the US — which is a much harder regulatory nut to crack — they are unlikely to be as competitive as BlockFi. There were also allegations that Nexo was spreading FUD about Chainlink while simultaneously partnering with them. Did Nexo take out a short position and start spreading rumors? Never a dull moment in crypto.
Other players in the lending & borrowing space include Unchained Capital, Cred (ICO Drops), and Salt (ICO Drops).

Wrap Up

While many companies in this category seem to be slowly adding more financial services, I don’t believe any of them are focused on the broader consumer market like we are. To use services like BlockFi, Nexo, or Celsius, users need to be onboarded and educated on how crypto works. At Genesis Block, we don’t believe that’s the winning approach. We think blockchain complexity should be abstracted away from the end-user. We did an entire series about this, Spreading Crypto.
For many of these services, there is additional friction due to ICO tokens that are forcefully integrated into the product (see NEXO token or CEL Token). None of these services have true banking functionality or integration with traditional finance —for example, easy offramp or spending methods like debit cards. None of them are taking DeFi seriously — they are leveraging crypto for only the asset class, not the underlying technology around financial protocols.
So are these companies potential competitors to Genesis Block? For the crypto crowd, yes. For the mass market, no. None of these companies are capable of reaching the billions of people around the world that we hope to reach at Genesis Block.

Round up of Cryptocurrency News #3 Week 20/07 - 26/07

Pssst! Hey you. Scroll down for commentary!
Important/Notable/Highlights:
Special Mentions:
You haven't had enough news? Here is some more:
Speculation:
You made it! :)
First up, SORRY! This has been a late post, I have my reasons don't question them (if you must know I'll be posting in the discord - one time only haha). Secondly, I am sure you can agree with me when I say "Wow!" What an incredible week it has been. Last week I thought it was going to take a couple more weeks for more moving price action when it had only taken a few days which has seen Bitcoin reach and pass the $10,000 region. We have also seen the total Market cap for cryptocurrencies increase from about 280B to over 300B (308B at time of writing) within just a few days. A huge injection of liquidity, about 40B, into the market and just to name a few of the best rises in the top 20 (on Coinmarketcap.com), the price of ETH BTC ADA have given good performances/positive responses (With this I will start adding screenshots at the end of each week for timestamp purposes).
This may be a combination from Binance, Mastercard, Paypal, Grayscale investments, VISA AND the DEFI sector. Let me explain... Last week we read about Binance integrating with the company Swipe (SXP) to issue there own debit card expanding the use and reach of cryptocurrency to 31 countries within Europe. Binance's Q2 scheduled token burn of $60.5 Million, this figure correlates with its exchange, margin and futures trading platforms where approximately 20% of profits get burned to increase the price of BNB token (careful as the price has been steady after the burn).
This week we find out Mastercard's expansion into the Cryptosphere as they expand and integrate with the Wirex team to issue a Mastercard-backed Bitcoin debit card, thus further extending the reach of cryptocurrency availability internationally.
"The cryptocurrency market continues to mature and Mastercard is driving it forward, creating safe and secure experiences for consumers and businesses in today’s digital economy " "...Our work with Wirex and the wider crypto ecosystem is accelerating innovation and empowering consumers with more choice in the way they pay"
Mastercard is also reaching out to other emerging cryptocurrency firms to apply to become principal members [Partners] with Mastercard as they have relaxed their digital assets program and look to expand into the Digital Assets and Blockchain environment.
Paypals expression of interest in cryptocurrency facilitiation may bear fruits as it is said Paypal has partnered up with stablecoin operator Paxos (who is already in partnership with Revolut in the US) to facilitate trading through a cryptocurrency brokerage which will enable other firms to integrate cryptocurrency trading functionalities with them. In my opinion this looks much more promising than the Libra association they pulled out from last October as regulations.
Grayscale Investments clears regulatory hurdle as they have been given the green light for its Bitcoin Cash Trust (BCHG) and Litecoin Trust (LTCN) to be quoted in over-the-counter (OTC) markets by US Financial Industry Regulatory Authority (FINRA).
“The Trusts are open-ended trusts sponsored by Grayscale and are intended to enable exposure to the price movement of the Trusts’ underlying assets through a traditional investment vehicle, avoiding the challenges of buying, storing, and safekeeping digital Bitcoin Cash or Litecoin directly.”
More green lights for Cryptocurrency in the US as regulators allow banks to provide cryptocurrency custody services (which may go further than just custody services). A little bit strange as it seems unnecessary and undermines one of the key factors and uses of cryptocurrency which is to be in complete control of your own finances... On another outlook this may be bullish as it allows US banks to provide banking services directly to lawful cryptocurrency businesses and show support for Bitcoin.
Visa shows support stating they have a roadmap for their further expansion into the Crypto sphere. Already working with Crypto platform Coinbase and Fold they have stated they recognise the role of digital assets in the future of money. To be frank, it appears to be focused on stable coins, cost effectiveness and transaction speeds. However they are expanding their support for crypto assets.
AND MOST IMPORTANTLY, DeFI! Our very own growing section in crypto. Just like the 2017 ICO boom we are seeing exorbitant growth and FOMO into the Decentralised Finance sector (WBTC, Stablecoins, Yield farming, DEXs etc). The amount of active addresses on Ethereum has doubled but with the FOMO on their network have sky rocketed their fees! Large use-cases of stable coins such as USDT ($6B in circulation using ERC-20 standard), DAI, TUSD, and PAX. $114M Wrapped Bitcoin (WBTC) on their network acts as a fluid side chain for Bitcoin and DEX trade volume has touched $1.6B this month. With all this action happening on Ethereum I saw the 24HR volume surpass BTC briefly on Worldcoinindex.com
In other news, Bitcoin has been set as a new precedent in a US federal court in a case against Larry Dean Harmon, the operator of an underground trading platform Helix. Bitcoin has now legally been ruled as a form of money.
“After examination of the relevant statutes, case law, and other sources, the Court concludes that bitcoin is money under the MTA and that Helix, as described in the indictment, was an `unlicensed money transmitting business´ under applicable federal law.”
Quick news in China/Asia as floods threaten miners and the most dominant ASIC Bitcoin mining rig manufacturer Bitmain loses 10,000 Antminers worth millions alledgedly goes missing or "illegally transfered" with ongoing leadership dispute between cofounders.
Last but not least, Cardano (ADA) upgrade Shelley is ready to launch! Hardfork is initiated as final countdown clock is switched on. At time of writing the point of no return has been reached, stress tests done and confirmation Hardfork is coming 29/07 The Shelley Mainnet upgrade is a step toward fast, capable and decentralised crypto that can serve billions of people. With the Shelley Mainnet is ADA staking rewards and pools! Here is a chance for us Gravychainers to set up a small pool of our own. Small percentage of profits going into the development of the community, and you keep the rest!
If you read all of my ramblings thanks heaps! I appreciate it! I have added an extra piece of reading called speculation. Most you can speculate on by just reading the headline some others have more depth to them.
Another post next week for a weekly round up! Where do you think the market is going? What is in your portfolio? Let us know in the Gravychain Discord Channel
See you soon!
🍕 Bring some virtual pizza to share 🍕
Come have a chat, stimulate a discussion, ask a question or share some knowledge. We are all friendly crypto enthusiasts up for a chat, supportive and want to help each other with knowledge and investments!
Big thanks to our Telegram and My Crypto HQ for the constant news updates!
P.S.
Dr Seuss collectables on the blockchain HECK YEAH! and Bitcoin enters NASCAR, remember when Doge did this? it was like when Doge was trending on TikTok.
... Oh yeah did I also mention Steve Wozniak is suing Youtube, Google over rampant Bitcoin scams. Wait, what? Sydney based law firm JPB Liberty is suing Google, Facebook and Twitter for up to $300B. Just another day in the Cryptosphere.

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.

Moh (Binance Angel)🇳🇬,
Please join me to welcome, “CHROMIA CEO & Co-founder, Henrik Hjelte” and “ CMO, Serge lubkin”
Oh, before we proceed, kindly introduce yourselves and tell us a bit about your roles at Chromia u/sergelubkin & u/henrik_hjelte.
Henrik Hjelte,
Ok, I’m Henrik, I’m CEO of ChromaWay that crated the Chromia project. My background is a bit mixed: developer for 30+ years (since 80: s), but I studied other things at university (economics, politics, social sciences philosophy). Life is more than computer you know… I worked with FInance/IT then started a web startup and got to know Alex Mizrahi who worked as a developer….
Web startup didn’t fly, but Alex showed me bitcoin. When I finally read the whitepaper I was blown away, and joined Alex colored-coins project, the first open source protocol to issue tokens. in 2013.
So, we started with open-source tokens (that kickstarted the blockchain industry. Then started company together 2014.
That is a long intro, I’ll shut up now… Thanks….
Serge,
I’m Serge, I’m assisting Henrik today and I work with Chromia marketing team as well as on some business development projects
Moh (Binance Angel)🇳🇬, , Question No 1 :
Kindly describe the CHROMIA project and what it aims to achieve?
Henrik Hjelte,
Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. There is a blog post about it, I’ll share later. On lines of code.
The aim of Chromia is to combine relational databases, which exist in every kind of organization, together using blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications.
https://blog.chromia.com/reasons-for-rell-compactness/
Moh (Binance Angel)🇳🇬,Question No 2:
What inspired the CHROMIA Core team to pick interest in CHROMIA project? what breakthrough have you achieved so far? what are the present challenges you’re facing and how are you planning to overcome them?
Henrik Hjelte,
We started with public blockchains, tokens in 2012, the world’s first stable coin with a bank 2015 (LHV). When coding that solution, peer to peer payments of Euro-tokens, we discovered we need performance reasons to store all data in a database. We needed to quickly know the “balance” of a user, and can’t loop through a blockchain. And slowly the idea grew that we can make the database INTO a blockchain, integrate completely with the transaction mechanism of a database. So, we did it as a private blockchain first (Postchain), used it for some projects, then came up with the idea to make a Public Blockchain based on it.
The motivation is that we felt we needed a better programming model for blockchains. Our CTO Alex has always been thinking of optimal solutions for blockchain technology and has lots of experiences thinking about it. Also: make real-world useful things. For example, we support free-to-play models since users do not need to own “our” token to USE apps, the application itself (often the developer) pays for hosting. And of course, great performance. Also: more knowledge of who runs nodes and risk level. So, it is more suitable for enterprises.
In Chromia the application (at the start the developer) decides Who should be allowed to run its own blockchain (every dapp has its own blockchain). You can also say on a higher level that we want to provide technology to create “Public applications”, a tool
that enables us to create a fairer world.
https://blog.chromia.com/towards-publicly-hosted-applications/
Moh (Binance Angel)🇳🇬, Question No 3 :
Why did you create your own blockchain instead of leveraging on existing and proven base layer protocol?
Henrik Hjelte,
None of the existing protocols are suitable to support large-scale, mainstream applications. We designed Chromia to give our users exactly what they want; fast support, useful features, with an affordable service cost. Other platforms do not have the ability to host data applications in a decentralized and secure way, as Chromia can. Chromia also has its own bespoke programming language that sets it apart from SQL-based platforms. It’s so easy to use, even non-developers can understand it!
The other big difference with Chromia concerns payments. Chromia gives its users freedom from having to pay for each transaction. With Chromia, you have the flexibility to decide how to set fees for your dapp
And when it comes to “proven base layer protocols”: they are just a few years at max. Chromia is built on top of Postgresql, that has been used in enterprises for decades, a really proven technology. And the Java virtual machine on top of that. This is proven tech, at core.
Moh (Binance Angel)🇳🇬, Question No 4 :
What is Postchain?
Henrik Hjelte,
Postchain is an open-source product of ChromaWay for enterprise clients and it’s the core technology on which Chromia is built.
Postchain is a replicated blockchain and database that offers highly resilient distributed database management with distributed control.
Postchain is the only product on the market that combines the immutable consensus of a blockchain and the properties of a real database management system (You know, the tech that built SAP, Facebook, Banks…) …
Postchain allows you to share information between companies and/or individuals in a secure and transparent way.
That is the low-level base of Chromia you can say
Moh (Binance Angel)🇳🇬,
Can you please name some of your clients that are using this service already?
Serge,
You mean products built on Postchain? Also, Stockholm Green Digital Finance, Green Assets Wallet that’s now functioning on Chromia Bootstrap Mainnet.
Big financial institutions
It’s only a beginning of course, but very promising one. https://greenassetswallet.org/news/2019/12/12/launch-of-the-green-assets-wallet
Henrik Hjelte,
We got a lot of attention with the Swedish Land registry; we did a joint project between them and banks and a telco etc on postchain as base.
Then, right now we do a large project with the Inter-American Development bank also about land-registration (processes) in South America.
We had a client, Stockholm Green Digital Finance, that did a system for green bonds (tracking environmental impact. Yes, as Sege says, it was later moved to Chromia…
Which is cool. Also, another external development company did that phase of the project, proving that other can build on our tech,4irelabs from Ukraine is their name. Some companies using the GAW: Blackrock. SEB Bank etc…
Also, we have done more projects, in Australia, asia etc. Oh Daimler too (the Mercedes company) …
Moh (Binance Angel)🇳🇬,
Lots of enterprise clients you’ve got. No wonder I do see the meme “CHR=ETH KILLER”
Serge,
It’s a meme from our supporters. But we believe we can coexist:)
For some niche things eth is good :)
So, no killing :D
Henrik Hjelte,
We want to work with partners too for this, we can’t do all projects ourselves. Also, for Chromia projects, ChromaWay company can help do support maintenance etc. So, it is not competing, it adds value to the ecosystem.
Yeah ETH is good too, for some applications. We are friends with them from colored-coin times.
And colored-coins inspired ETH, and ETH inspires us.
Moh (Binance Angel)🇳🇬, Question No 5 :
Lastly, CHROMIA is already doing very well in terms of business. You just got listed on BINANCE JEX, you are on-boarding new clients and dishing out new features. But what’s next? Is there anything to be excited about?
Henrik Hjelte,
Plans for 2020 are to both release a series of dapps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release the mainnet.
Dapps are now being made by us as well as others. We do a decentralized social network framework called Chromunity, now released to TestNet. It is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public.
https://testnet.chromunity.com/
Games coming are:
Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff. Already on TestNet and you can take a peek on it at https://www.minesofdalarnia.com
more coming…
Krystopia 2, novas journey. A puzzle game done by Antler Interactive. Could only find trailer though: https://www.youtube.com/watch?v=-G95-Dw3kI4
However, we have even larger ambitions with blockchain gaming…
We are doing A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
Another exciting relase is an indie game Chain of Alliance, done by two external developers. It is a strategy game with full-logic on blockchain. Public release on TestNet on May 22!
More coming in 2020: Other dapps from other companies, one in impact-tech.
That is a serious app, Chromia also works outside gaming and social media for enterprises and startups
And I hope some of you will do something, we want to support dapps on the platform so reach out to us…
Moh (Binance Angel)🇳🇬,
When can we be expecting the mainnet? Any approximate time? I’m sure the community will really excited to have that info
Serge,
It’s now in Bootstap phase, so it’s technically already functioning. MVP will be very soon
Stay tuned;)
Twitter questions Vs answers
Ellkayy,
What’s the unique thing in Chromia that no other blockchain has, that makes you the better option?
Henrik Hjelte,
Unique: Chromia is the only blockchain that also has a real, proper database built-in. And blockchain is about managing data in a shared context. How to best managed data was solved in computer science already. So far, it is the relational algebra model that is used in 100% of all enterprises, and has an 85% market share. Chromia is the only blockchain that use that model and that power.
Ellkayy,
Why Chromia use RELL and not SQL or JavaScript? Can developers with other language knowledge use Chromia?
Serge,
Rell is the only language on the blockchain side. You can combine with anything on client-side, although now client only exists for JS/TS, C# and Java/Kotlin. Rell is a language for relational blockchain programming. It combines the following features:
1 Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
2 Normal programming constructs: variables, loops, functions, collections, etc.
3 Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
Rell aims to make programming as convenient and simple as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects prior to run-time.
Roshan DV,
I have been monitoring your project for a while but some concerns about it: Your project will build your own core network, so you have more visibility than Ethereum and NEO. These are projects that were born before and which also have a very large community. And what can assure you that your project will guarantee the functionalities that you have defined?
Henrik Hjelte,
What came first? I want to remind that Vitalik was in the colored-coins project, led by our CTO and we had blockchain in production before ETH and NEO etc existed. We are the old dogs…
Large community: We are part of the same community. When developers are fustrated and want to try new tech, they go to us from other blockchains.
Also, we have a large potential: SQL (close to Rell and our tech) is the world top 3 language. Bigger than Java. Bigger than PHP. Only beaten bny HTML and javascript. Soliditiy is not on top 20 list. THere are millions of developers that know SQL. That is potential for community… (source is Stackoverflow annual programming survey).
Paul (Via Manage),
What are the utilities of Chromia and what purpose does the Chromia coin serve?
Serge,
Chromia meta-token called Chroma (CHR). It is used in Chromia to compensate block-producing nodes by fees. In Chromia, fees are paid by dapps, which can in their turn collect fees from users. Chromia provides mechanisms which balance the interests of developers and users. Dapp tokens can be automatically backed with Chroma, providing liquidity and value which is independent of investment into the dapp. Dapp investors can be compensated in Chroma through a profit-sharing contract. For developers, Chromia offers the opportunity to derive income from dapps. This incentivises the creation and maintenance of high quality dapps because better dapps generate more income and create more demand for tokens owned by the developer. The Chromia model is designed to support sustainable circular economies and foster a mutually beneficial relationship between developers, users, and investors.
Idemudia Isaac,
Thank you very much u/henrik_hjelte u/sergelubkin
You stated your plans for 2020 is to release series of dApps. What kind of large scale, mainstream decentralized application and $Chromia products do you think is suitable for the Nigerian environment?
Henrik Hjelte,
Actually, this is why we want to work with partners. We cannot know everything, For African market we have seen of course payments/remittances (but it has fallen out of trend). We would love to do real-estate /land-registration but we understand we need a strong local partner (more than a single person, a real company or organization driving).
●CC● | Elrond 🇵🇭,
What plans do you have to building a vibrant global community around Rell? And how would you go about encouraging/incentivising such ‘Rellists’ around the world to build dApps on Chromia? u/henrik_hjelte u/sergelubkin
Henrik Hjelte,
For developers (I am one too, or used to be) you normally need to prove a few things:
\ That the tech is productive (can I do apps faster?)*
\ That it is better (less bugs, more maintainable?)*
Then the community will come. We see that all the time. Look at web development. React.js came, and developers flooded to it. Not because of marketing on Superbowl, but because it was BETTER. Fewer bugs and easier to do complex webapps.
So, at core: people will come when we showcase the productivity gains, and that is what we need to focus on.
●CC● | Elrond 🇵🇭,
Why do you choose to build Chromia token on ERC20 instead of other blockchain such as BEP2, TRC20…or your own chain while ERC20 platform is very slow and have a case of fee? u/henrik_hjelte u/sergelubkin
Serge,
So far Ethereum has the best infrastructure, it’s the oldest and most reliable network for tokens. It also became the industry standard which exchanges utilize. We will transfer 80% of all erc20 tokens to our Chromia blockchain when it’s ready for that.
Koh,
In your whitepaper it says in the upcoming version of ChromiaWallet that it will be able to function as a Dapp browser for public use. Q) Will it be similar to the Dapp browser on Trust Wallet?
Serge,
It’s live already try it http://vault-testnet.chromia.com/
It’s the wallet and a dapp browser
CHROMIA is SOLID,
Your metamorphosis is a laudable one,surviving different FUD, how have you been able to survive this longest bear market and continue building and developing cos many projects have died out in this time period!
Henrik Hjelte,
You need to know we started a company before ETH existed. There was 0 money in blockchain when we started. I did it becuase it was fun, exciting tech and MAYBE someone would be interested in the thing we made “Tokens”…
We were never in the crazy bull-market, manly observed the crazies from the side. We fundraised for CHR in a dip (they called it bear market). ChromaWay the company also make money from enterprises.
Алекс,
What is SSO?
What makes it important for chromias ecosystem?
Why should we users be attracted to it?’
Serge,
Chromia SSO is perhaps the most important UX improvement that Chromia offers the decentralized world. It revolutionizes the way users interact with dapps. Any dapp requires users to sign transactions, that means they need a private key. Control of the private key is control of any and all dapps or assets associated with it. This means that private keys have an especially stringent set of security requirements in a blockchain context — they control real value, and there is no recourse if they are compromised or lost. https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/
Olufemi Joel,
How do you see the Chromia project developing in 3 to 5 years, both on the commercial level and on the evolution of the company? What are the plans for expansion in different regions? Are you going to outsource the team/skills or keep it centralized and set up offices?
Henrik Hjelte,
I take part of the question. On outsource: we were a distributed team from day one, with co-founders from 3 countries (still living there). We are distributed now, Ukraine, Sweden, Vietnam, Croatia, China are “hubs” then we have individuals too. No big plan, just where we found great developers…
Park Lee, u/henrik_hjelte
You claim CHOROMIA have fast support, useful features with an affordable service cost. That fast and the fees are cheap but can you guarantee stability?
What’s the Algorithms which are used by CHROMIA for that fast? And Can you explain it?
Serge,
We use PBFT protocol with some features of DPOS, this plus sidechains parallelism offers almost unlimited speed and scalability. We also use the feature called anchoring to secure all transactions in batches on Bitcoin blockchain.
Mario Boy,
What are you guys trying to achieve as an end goal? The next Ethereum? Or the next enterprise version of Ethereum? Or something different?
Henrik Hjelte,
The end goal… good question. When we started in 2014 there were no other blockchain companies, so we wanted to do the best blockchain technology in order to enable a decentralized world with more fair applications. And that is what we still do. Technology/software that can enable people to make a fairer world
Erven James Sato,
“STAKING” is one of the STRATEGIES to ATTRACT USERS and ACHIEVE MASS ADOPTION
Does your GREAT PROJECT have plan about Staking?
Serge,
Yes, we announced our staking plans couple of months ago https://blog.chromia.com/on-providers-and-stakes/
We are working with our current partners to make it accessible for general public.
Chizoba,
I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two?
Henrik Hjelte,
ChromaWay the company started Chromia from code done as postchain. This is normal in open-source development, a company that leads development. But Chromia will be a decentalized network, so ChromaWay will not make direct money out of it more than if we have a role as a Provider (and get payed for hosting). ChromaWay can indirectly make money from optional support and maintenance etc. Also, this, perfectly normal in open-source world.
And it also benefits Chromia that there is a market for support.
A market open for competition.
No special treatment for “ChromaWay”
Enajite,
How to start coding on Chromia?
Henrik Hjelte,
Go to https://rell.chromia.com and follow the tutorial. Enjoy the free time you get compared to other blockchain languages…
●CC● | Elrond 🇵🇭,
Chromia process 500 TPS, these is slow compare to other Blockchains, where we can see now 60K TPS if more capacity require, how can that be? u/henrik_hjelte u/sergelubkin
Serge,
Yes, if you need faster speed you can use parallelism by having multiple blockchains for your dapp. Also, by optimization and better architecture sky is the limit.
Delphino.eth ⟠,
Can we consider Chromia an hybrid? For its mixing of Blockchain and a Database?
Henrik Hjelte,
Yes and no. I want to stress that Chromia is a FULL blockchain. It is not only “inspired”. It is a blockchain AND a database.
I tend to think about Hybrid more in the usecases that you might have as a customer. For example, a bank might want to have some data/transactions private (as a private blockchain) and have another half of the application with public data (on Chromia). So that is a hybrid solution, and Chromia ROCKS in that segment since it is the only blockchain that is complete relational database (what the normal world uses anyway for 85% of all applications)
Example area: “open banking”
Steve bush,
How will Chromia I have any empower Investors, Companies, Developers, Platform Users to
deliver impactful solutions and bring value to people all over the world?
Henrik Hjelte,
In order to make blockchain go big, we need to have users. Users need to be able to use apps with ease. Chromia have features like single-sign on (ease of use), but importantly do not require owning tokens to USE apps.
Also, it needs to be easy to make applications. For example, if you are a student in US and came up with an idea, you want to make an application for your school. Let’s call it “thefacebook”. You code something in PHP and MySQL. DID YOU SEE THAT. SQL. SQL.SQL. It is the same tech that Chromia has but no one else in the blockchain business. SQL rules the world if you look outside the crypto bubble. Google the Oracle head-office… 100% of all enterprises use it… Because it is easy and powerful.
And we even improve on SQL with Rell….
So, compare that with a hacky virtual machine that have a few years…. 😊
August,
“Mines of Dalarnia” is a game that has caught my attention a lot, due to its simplicity and quality. But in the time that I have used it I have not been able to differentiate between the Chromia blockchain of this game and that of the competition? What other games do you have next to develop? I would like to give ideas in those games like a Gamers!
Henrik Hjelte,
We thought about in corona time sports club might want to engage more with their fans digitally. And of course, E-Sports is getting a real momentum as the young generation grows up. Now a bit sad that all games are centralized. My daughter will be sad when (at some day?) they will close down roblox… it happens to all centralized apps eventually… that is what we fix. Power to the Public to control apps and their future. I’ll repost again Alex post. Sorry I like it a lot… https://blog.chromia.com/towards-publicly-hosted-applications/
Bisolar,
Good day Chromia team from a Chromia fan
Can you tell us Chromia’s geographical focus at the moment and the proces it follows for it BUSINESS DEVELOPMENT?
What factors do you consider before identifying NEW MARKETS to enter?
Serge,
Chromia will initially focus on community building in China, Korea, US and Europe. The focus of community growth will gradually expand to other markets as the project gains popularity.

Emmanuel,
I want to know the current structure of your roadmap? What is the future roadmap of CHROMIA? Is there any key milestone coming???
Henrik Hjelte,
It is easy to do a roadmap; anyone can make a pape plan. But I think they are used in the wrong way. Software is hard, blockchain is even harder because it NEEDS TO BE SECURE. No MVP releases. We cannot even have roadmap deadlines and skimp on quality. Where we are now though is: Rell language finished so much that developers can write apps and see its magic. We have external devs doing dapps. We have the first phase of mainnet. We have a series of releases coming up. We will release mainnet when it is secure enough, and gradual roll out. I think quite soon, development is going great at the moment, a bit quicker than we though.
Ellkayy,
Why doesn’t Chromia transactions use gas? How do you power transactions then?
Serge,
Main feature of gas in Ethereum is to pay for transactions for miners get rewards. In our scenario Providers get rewards from dapp owners. So dapp owner pays for storing their dapp. It’s like Amazon Web Service model. Then dapp owner can monetize it in its own way.
Ellkayy,
Many developers don’t know RELL, just Solidity and SQL. Is this a barrier or threat to Chromia? Why RELL is better?
Henrik Hjelte,
Very few developers know Solidity. Do a search on github. I referred previously to stackoverflow programming language survey results. https://insights.stackoverflow.com/survey/2019#technology
If you know SQL, you learn Rell in a day.
SQL is the top 3 language here. I’d say there are millions that can easily jump to Rell.
Soldity or other blockchains, not on top 20 list even.
Rell is a hipper, nicer version of SQL that is also a “normal” programming language.
Developers like to learn new things, new languages. Otherwise we would be stuck with PHP, the DOMINANT language. Well, is it still? Seems javascript and react.js and node etc is taking over…

Hi everyone. Pleased to be here! Thank you for taking your time to join me.
I’m the Chief Business Development Officer for TomoChain.
Educationally I graduated university with degrees in both Industrial Engineering and Economics from Georgia Tech, and later earned an MBA from the Wharton School of Business.
I grew up as a gaming addict and have a video game collection that is a bit unwieldy. Dozens of consoles and, at one point, over 13 classic arcade machines.
So, before crypto, I spent much of my profession in the gaming space. I was a Game Designer, Game Producer, and eventually Studio Head for a major games studio that was recently purchased by Rockstar Games. I have run my own game-related tech businesses as well.
I fell into crypto back in 2014, and over time it became a second passion of mine as I began to truly understand the value of decentralization. True ownership of data was not possible until Bitcoin came along and that is simply a powerful and game-changing message to a world structure built on an opposing foundation.
Brief Introduction

https://preview.redd.it/8p7jm15ul5t41.png?width=739&format=png&auto=webp&s=8b572bdee2c56ffa29a1d628dda7332fac0fac50
TomoChain is a Public Blockchain powered by Proof-of-Stake Voting. TomoChain launched into Mainnet 1 year ago in December 2018. It is secured by 150 Masternodes, of which I’m proud to be an operator myself. TomoChain is EVM Compatible and runs at a speedy 2000 TPS with a 2 Sec Blocktime. Gas fees are almost zero too.
Based out of Vietnam, TomoChain is Southeast Asia’s largest public blockchain. We are focusing on developing a full suite of DeFi products. We also have commercial and enterprise clients. TomoChain has a number of major crypto-partnerships including notables like Neo Blockchain, Chainlink and Crypto.com. Our Masternode network is run by some of the most recognizable players in the space as well, including Neo Global Capital, CoinGecko, HashQuark, KuCoin, and more large players are on the way.
TomoChain earned its place onto Binance.com with a fee-free listing last year by winning the BinanceDEX community vote in August 2019. Binance has written us up in a detailed Binance Research Report and awarded us the V-Label. We have also been in a number of their reports, including those related to Dapps and DeFi. We have been interviewed by Forbes.com official and had an in-person interview at NASDAQ, in the heart of Times Square, about TomoChain and our upcoming TomoX Protocol.
In China, specifically, we have been integrated into and have solid relationships with various blockchain players including HashQuark, HashKey, CoboWallet, Conflux, and many others. We launched an Ecosystem Development partnership with Neo Blockchain last December and co-hosted a meetup + workshop with them as well.

GEARED FOR REAL WORLD USE
Now, let’s talk about how TomoChain has been built for real-world use.
We’re looking at Payments & DeFi as low hanging fruit when it comes to user adoption and TomoChain is developing a suite of tools to support this. The biggest challenge for having users benefit from Blockchain on a day-to-day basis is how much friction is involved to acquire, store and use it. Even stable coins are dual currency systems. The Stablecoin and then the Native Token to pay gas fees. Blockchain is simply not user-friendly.
Our view is that the true solution for Blockchain adoption by the world is end-users shouldn’t need to know they are using blockchain technology at all. It should be a hidden technology layer, similar to payment processor settlements or even the internet distribution centers/routers that power this very AMA we’re all participating in right now. Do we need to know the underlying technology infrastructure to use them? Nope.
We are developing a system to hide this friction, so the TomoChain blockchain can be integrated into real-world applications that you use every day on mobile or web.
There are 3 protocols that we are building to enable this future: (1) TomoZ: Zero Friction (2) TomoX: The DEX Protocol (3) TomoP: The Privacy Suite.

https://preview.redd.it/irwduto4m5t41.png?width=741&format=png&auto=webp&s=56e21c8e56b86af197344d7a043d073456c53181
TomoZ: Zero Friction - Our TomoZ protocol is a core starting point to the solution for mass market use of blockchain technology. TomoZ: Zero Friction allows for token issuance and use by having gas fees paid by the token itself. That means you don’t need TOMO to send transactions. You don’t even need to know you’re using the TomoChain blockchain.
So you could buy a cup of coffee at a café using loyalty points that are TomoZ tokens. The customers redeem for their coffee or earn it, but they don’t even have to know it’s a blockchain token which they actually own.
This approach is structured to enable the next million-plus users to utilize blockchain as a technology layer. After all, the real value of any Blockchain is in its utilization of high-quality transactions.
Now, TomoZ transactions aren’t FREE. It actually does use TOMO, but that’s hidden from the end-user. The way it works is that the token issuer deposits a small amount of TOMO into a pool. Every time the token is sent, TOMO is taken from this pool to pay the Masternodes.
The key is that the end-user doesn’t need to get involved with internal workings, which is why we call it the Zero Friction protocol
Now let’s talk about TomoX: The DEX Protocol
TomoX is an upcoming DEX Protocol that allows anyone to launch their on permissionless Decentralized Exchange in minutes. It requires very little technical knowledge making it a near turn-key solution.
TomoX is the fastest DEX experience since it’s a Layer 1 protocol. This means it’s run and secured by the entire TomoChain network. Our Masternodes manage the DEX instructions directly, rather than other DEXs that operate as a Layer 2 protocol. What this means is TomoX DEXs will operate at about 50x faster than a typical 0x exchange. That significantly improves the end-user experience.
TomoX DEX operators have access to a shared liquidity pool across all DEXs. That means a user buying on one DEX can be matched with a user selling on another DEX. Of course, Operators can customize and choose which tokens to include.
TomoX is fully decentralized since the Order Book is on-chain. Many other semi-decentralized exchanges store the OB on a centralized service in order to speed up the execution. That means there is a centralized point of weakness for them. TomoX minimizes custody and security challenges that centralized exchanges have too since all users are always in possession of their assets.
TomoX is currently in testnet and you can checkout TomoChain’s own DEX, aptly called TomoDEX, here: https://dex.testnet.tomochain.com/
Here is a link to get some free Testnet TOMO that can be used on the testnet version of TomoDEX: https://faucet.testnet.tomochain.com/
And finally, there is TomoP: Privacy Suite - TomoP is currently in testnet and is going to be the FASTEST way to send tokens privately. 2-4 seconds fast!
Any token issued on TomoChain will be able to utilize TomoP to send privately and anonymously. And that’s not all. We are including access to wrapped BTC, ETH, USDT, and other tokens that can also utilize the blazing speed and privacy that TomoP will offer.
Dapp privacy is a major part of TomoP. It is going to allow for the creation of Dapps to be built to handle customer data with true privacy, including from the Dapp operators themselves. This can jumpstart a new wave of applications geared towards hiding user information, transactions, assets owned, etc.
We are issuing a new token standard (TRC21p) which will be purely private. The only data available will be on its token supply. Token issuers can optionally provide auditing access to enforcement authorities to meet regulatory compliance. What this means is if the next Global PayPal/Skrill/Alipay competitor can build their service right on TomoChain and meet the most basic criteria required to stay above board in many jurisdictions.

Questions from the host
1. It’s been stated that TomoChain was on track to be a cash flow positive business, is it currently cash flow positive? What services or products is it offering to bring in this revenue?
Yes, absolutely. Our plan is to be cash flow positive this year. This really goes back to the level of experience our executive team has. Everyone is seasoned, having come from different fields, in big business and startups. Before the crazy boom of ICOs and IEOs, raising funding for traditional startups required considerable proof that there was market fit, that there were actual customers to drive revenue, and a model for growth.
We knew that TomoChain’s funds raised during the ICO were for a space that has yet to prove itself so the company had to be smart in budgeting for an uncertain future. And part of that initial preparation was selling much of the ICO proceeds into fiat. Something MANY blockchain startups did not do, largely due to ambitious teams that are also headed by very inexperienced leaders. So while the bubble burst, we had capital to continue operations and to even scale it.
And, we ARE running a business. A sustainable business requires us to identifying areas to generate income in order to minimize risk and to sustain the business in the long term. So we do both consulting and services work by helping clients to develop wallets, launch tokens (Orbyt), build exchanges (AIS), and of course enterprise solutions on the blockchain of which we have clients based out of Japan and in the Middle East using blockchain for traceability solutions across various industries from automotive, healthcare, and food.
2. What is the most strategical step TOMO is doing to bring adoption of TOMO coin to our daily lives?
Empowering businesses with a truly scalable blockchain that can be used by thousands and millions of users. We see user adoption of blockchain coming from businesses that base their solutions on blockchain technology. And, TomoChain has a number of real income-generating companies that have built on us, from exchanges to payment services to enterprise clients. Not bad for 1 year I say, especially during a stagnant market. Here are some examples.
UcarPac – A Top 10 User Car company in Japan is building traceability solutions on the blockchain. We completed a POC at the end of last year. After the assessment, the client decided it was solid and commissioned Phase 2 to expand the development of the project for commercialization purposes
Triip Protocol – Triip is a destination service for travelers to book vacations powered by Blockchain. Triip is a Shark Tank Vietnam alumnus, and the first ICO on TomoChain. Users can book tours and staycations using Triip or TOMO tokens.
WisePass – A service that sells subscription services to get discounted Starbucks, Singha Beer, and even makeup (of all things) integrated TomoChain as a payment solution
“Undisclosed Vendor” – Soon to be announced, a large player in the corporate gift giving business is also launching a Dapp on TomoChain to allow for them to make purchases with TOMO across thousands of items.
Maka - A peer-to-peer marketplace to conveniently buy/sell TOMO and other blockchain tokens using standard payment gateways, including e-wallets and bank transfers.
Coin98 – A local Vietnam crypto media company launched an App to allow for their community to earn their TomoChain token called C98 and use it for products and services geared around investors and gamers. The reception has been HUGE. 95,000 users and generating 500K+ transactions on our blockchain within 3 months of their launch! They are proving that innovative new business models can be adopted relying on and being blockchain specific.

3. Do you have any plans to collaborate with developers or attract more Dapps built on TomoChain?
We are today. Our founders run the largest Blockchain Developer community in Vietnam and we work with a number of them to help develop solutions on the blockchain.
Our team has held Hackathons a few times over the last couple years and we have done developer workshops too, including one with Neo Blockchain. And this year we are working closely with educational institutions to launch blockchain courses in Vietnam.
Every Dapp developer we work with is a partner. We try to provide as much support as possible, both technical and marketing. A number of Dapps are games on TomoChain and we hold contests regularly to promote the developers and their titles.
Since we are focusing on alleviating the friction of blockchain technology, we are building out an API that will make it even easier for developers to integrate blockchain into standard applications. This is intended to allow standard non-blockchain application developers to operate in an environment they are accustomed to while also having the benefit of blockchain technology accessible.
Onboarding more developers will take time. However, I’m confident we’re on the cusp of something wonderful in the coming years that will change the relationship between users and applications enabled by blockchain. Entirely new economic structures can be set up since it’ll be the users owning all of their data for the first time in digital history. And true ownership is a powerful motivator that can be harnessed by innovative blockchain businesses.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.
