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 summaryDragonchain 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 PoCIn 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.
A live proof of concept showing hundreds of thousands of transactionsOn 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
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:
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.
How it works & scales
Architectural ScalingDragonchain’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 ScalingAn 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 DeploymentDragonchain 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 ScalingDragonchain’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.
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
How to run itBuilding 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...
ArchitectureDragonchain 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.
APIs (on chain & off)
Known issues or tradeoffs
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.
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.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
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 considerDragonchain’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.
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 transactionsDragonchain 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.
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.
Users should be able to view their balances & transactions via a blockchain explorer-style interfaceFrom 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 & simpleWithdrawing 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
Documentation should be clear and completeFor 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 Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
TIMECommunity 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 DenDragonchain 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 elseUsers 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 elseThrough 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 offlineIf 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 availableTo 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 pointsSee above
Compatibility with HSMs & hardware walletsFor 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.
Minting/distributing tokens is not performed by Reddit directlyThis 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 scalableThis is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferredDragonchain is fully open source (see section on Disney release after conclusion).
ConclusionWhether 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 SourceThe 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.
Open SourceIn 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:
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.

On August 5th 2020, Satoshi’s Angels hosted an AMA for CoinEx on “How BCH and Avalanche Are Bringing Financial Freedom to 6 Billion People” on a Chinese platform Bihu. During the 100-minute event, Haipo Yang of ViaBTC and CoinEx, and Emin Gun Sirer of AVA Labs shared their in-depth views on such topics as different consensus mechanisms, community governance, IPFS, Defi. And Haipo explained why he wants to fork BCH. This is the full text.
You can check out the full AMA here (mostly in Chinese with some English translation).
Cindy Wang (Satoshi’s Angels): There are news saying that you are to fork BCH. Is it a marketing makeover? Are you serious about it?
Haipo Yang: It’s definitely not a marketing makeover. But the details are not decided yet.
Over the past three years, the BCH community has gone through multiple discussions from reducing block time, changing mining algorithms, adding smart contracts, etc. But none of these disputes have been well settled.
BCH is a big failure in terms of governance. A lack of good governance has made it fall in disorder. It is too decentralized to make progress.
You may know that the first BCH block was mined by ViaBTC. And we gave a lot of support to it indeed. But we didn’t dominate the fork. The Chinese community in particular thought I had a lot of influence, but it was not true.
I think the whole community is very dissatisfied with Bitcoin ABC, but it is difficult to replace them or change the status quo. So I am thinking of creating a new branch of BCH. The idea is still in early stage. I welcome anyone interested to participate and discuss it with me.
Wang: Professor Emin, what’s your attitude to fork? Do you think it’s a good timing to fork BCH?
Emin Gun Sirer: I am a big fan of BCH. It adheres to the original vision of Satoshi Nakamoto. I like the technical roadmap of BCH. But just like what Haipo mentioned, BCH lacks a good governance mechanism. There are always something that can cause BCH community to divide itself.
But I think it’s not enough to just have a good governance mechanism. There are many good proposals in the community but failed to be adopted in the end. I think BCH needs social leadership to encourage discussion when there are new proposals.
Wang: We are all curious to know How Avalanche got its name?
I know that Avalanche doesn’t mean well in Chinese. But in English, it’s a very powerful word. Avalanche represents a series of algorithms piling together like a mountain. When decisions slowly form, the ball (nodes in the network) on top of the mountain starts going down the hill on one side, and it gets bigger and bigger, and like an avalanche and it becomes unstoppable, making the transaction final.
Wang: Prof. Emin, I know that you are a big blocker. Have you ever considered implementing Avalanche based on BCH? Why create another chain?
Sirer: Of course I considered that. Satoshi Nakamoto consensus is wonderful, but the proof-of-work mechanism and Nakamoto consensus base protocols have some shortcomings, such as network latency, and it is hard to scale. Avalanche, instead, is totally different, and is the new biggest breakthrough in the past 45 years. It is flexible, fast, and scalable. I’d love to implement BCH on top of avalanche in the future, to make BCH even better by making 0-conf transactions much more secure.
Wang: As an old miner, why did CoinEx Chain choose to “abandon” POW, and turn to POS mechanism?
Haipo: Both POW and POS consensus algorithms have their own advantages. POW is not just a consensus algorithm, but also a more transparent and open distribution method of digital currency. Anyone can participate in it through mining.
POW is fairer. For a POS-based network, participants must have coins. For example, you need to invest ICO projects to obtain coins. But developers can get a lot of coins almost for free. In addition, POW is more open. Anyone can participate without holding tokens. For example, as long as you have a computer and mining rigs, you can participate in mining. Openness and fairness are two great features of POW. POS is more advanced, safe and efficient.
POS is jointly maintained by the token holders, and there is no problem of 51% attacks. Those who hold tokens are more inclined to protect the network than to destroy the network for their own interests. To disrupt the network, you need to buy at least two-thirds of the token, which is very difficult to achieve. And when you actually hold so many coins, it’s barely possible for you to destroy the network.
POW has the problem of 51% attack. For example, ETC just suffered the 51% attack on August 3. And the cost to do that is very low. It can be reorganized with only tens of thousands of dollars. This is also a defect of POW.
In addition, in terms of TPS and block speed, POS can achieve second-level speed and higher TPS. Therefore, CoinEx Chain chose POS because it can bring a faster transaction experience. This is very important for decentralized exchanges. Both POW and POS have their own advantages. It’s a matter of personal choice. When choosing a consensus mechanism, the choice must be made according to the characteristics of the specific project.
Wang: Ethereum is switching to ETH 2.0. If they succeed, do you think it will lead the next bull market?
Sirer: If Ethereum 2.0 can be realized, it must be a huge success.
But I doubt it can be launched anytime soon considering that it has been constantly delayed. And even if it comes out, I am not so sure if it will address the core scaling problem. And the main technology in Ethereum 2.0 is sharding. Sharding technology divides the Ethereum networks into small parallel groups, but I think what will happen is everyone wants to be in the same “shard” so the sharding advantages might not be realizable in Ethereum 2.0.
Avalanche supports Ethereum’s virtual machine, and Avalanche can realize 1 second level confirmation, while with sharding finalizing confirmation takes 5–6 seconds at best. Avalanche approach to make Ethereum scale is superior to Ethereum 2.0. There are many big players behind Ethereum 2.0, and I wish them success. But I believe that Avalanche will be the fastest and best Smart Contract platform in the crypto space, and it is compatible with Ethereum.
Wang: Why is Avalanche a real breakthrough？
Sirer: Avalanche is fundamentally different from previous consensus mechanisms. It’s very fast with TPS surpasses 6500, which is three times that of VISA. Six confirmations can be achieved in one second. Compared with the POW mechanism of Bitcoin and Bitcoin Cash, Avalanche’s participation threshold is very low. It allows multiple virtual machines to be built on the Avalanche protocol.
Avalanche is not created to compete with Bitcoin or fiat currencies such as the US dollar and RMB. It’s not made to compete with Ethereum, which is defined as the “world’s computer”. Avalanche is positioned to be an asset issuance platform to tokenize assets in the real world.
Wang: How do you rank the importance of community, development, governance, and technology to a public chain?
Sirer: These four are like the legs of a table. Every foot is very important. The table cannot stand without strong support.
A good community needs to be open to welcome developers and people. Good governance is especially important, to figure out what users need and respect their voices. Development needs to be decentralized. Avalanche has developers all over the world. And it has big companies building on top of Avalanche.
Yang: From a long-term perspective, I think governance is the most important thing, which is the same as running a company.
In the long run, technology is not important. Blockchain technology is developed based on an open source softwares that are free to the community. Community is also not the most important factor.
I think the most important thing is governance. Decentralization is more about technical. For example, Bitcoin, through a decentralized network method, ensures the openness and transparency of data assets, and the data on the chain cannot be tampered with, ensuring that the total amount of coins has a fixed upper limit.
But at the governance level, all coins are centralized at some degree. For example, BCH developers can decide to modify the protocol. In a sense, it is the same as managing a company.
Historically, the reasons for the success and failure of companies all stem from bad governance. For example, Apple succeeded based on Steve Jobs’s charisma, leadership and the pursuit of user experience. When Jobs was kicked out, Apple suffered great losses. After Jobs returned, he made Apple great again.
Issues behind Bitmain is also about governance. Simply put, governance requires leaders who have a longer-term vision and are more capable of coordinating and balancing the resources and interests of all parties to lead the community.
In the blockchain world, many people focus on technology. In fact, technology is not enough to make great products. User experience is most important. Users don’t care about the blockchain technology itself, but more concerned about whether it is easy to use and whether it can solve my problem.
We need to figure out how to deliver a product like Apple. The pursuit of user experience is also governance in nature. And governance itself lies in the soul of key leaders in the community.
Realize tokenization of assets in.
Wang: Speaking of asset tokenization, I would like to ask Haipo, do you think the market for assets on the chain is big?
Yang: It must be very big. We need to see which assets can be tokenized.
Assets that can be tokenized are standardized assets, sush as currencies and securities.
There may be only tens of thousands of stocks currently traded globally. There are also tens of thousands of tokens in the crypto space. I believe that millions or more of assets will be traded and circulated in the future. This can only be realized through decentralized technology and organization.
The market for assets tokenization will be huge. And at present, the entire blockchain technology is still very primitive. Bitcoin and Ethereum only have a few or a dozen TPS, which is far from meeting market demand. This is why CoinEx is committed to building a decentralized Dex public chain.
Wang: Avalanche’s paper was first published on IPFS. What do you think of IPFS?
Sirer: I personally like IPFS very much. It is a decentralized storage solution.
Yang: There is no doubt that IPFS solves the problem of decentralized storage, and can be robust in the blockchain world, and can replace HPPT services. But there are still three problems:
Wang: What do you think of Defi?
Yang: I want to talk about the concept first.
Broadly speaking, the entire blockchain industry is DeFi in nature. Blockchain is to realize the circulation of currency, equity, and asset value through decentralization.
So in a broad sense, blockchain itself is DeFi. In a narrow sense, DeFi is a financial agreement based on smart contracts. DeFi, through smart contracts, can build applications more flexibly. For example, before we could only use Bitcoin to transfer and pay. Now with smart contracts, flexible functions such as lending, exchange, mortgage , etc. are available. The entire blockchain industry is gradually evolving under the conditions of DeFi. DeFi will definitely get greater development in the future.
Sirer: I think Defi will definitely have a huge impact. DeFi is not only an innovation in the cryptocurrency field, but also an innovation in the financial field. Wall Street companies have stagnated for years with no innovation. Avalanche fits different DeFi needs, including performance and compliance. In the future, not only will Wall Street simply adopt DeFi, but DeFi will grow into a huge market that will eventually replace the traditional financial system.
Questions from the community:
1. How does Avalanche integrate with DeFi?
Sirer: At present, all DeFi applications on Avalanche have surpassed Ethereum. What can be achieved on Ethereum can be achieved on Avalanche with better user experience. We are currently connecting with popular DeFi projects such as Compound and MakerDao to add part of or all of their functions.
At present, Avalanche is working on decentralized exchange (DEX). The current DEXs are limited by speed and performance but when they are built on top of Avalanche it will be real-time and very fast.
2. How many developers does BCH have?
Yang: I think it does not matter how many developers there are. What matters is what should be developed. I watched Jobs’ video the other day, and it inspired me a lot. We are not piecing together technology to see what technology can do. It’s we figure out what we want first and then we use the technology we need.
The entire blockchain community worship developers. Such as they call Vitalik “V God”. It’s not necessary to treat developers as wizards. Developers are programmers, and I myself is also a programmer.
ViaBTC has a development team of over 100 people, including core members from Copernicus (a dev team formerly belonged to Bitmain). Technically we are very confident to build faster, stabler, and better user experience products.
Can the early success of major crypto exchanges propel them to winning the broader consumer finance market?submitted by mickhagen to genesisblockhq [link] [comments]
This is the first 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 powerful technology to reach the masses. We believe a crypto-native company, like Genesis Block, will become the bank of the future.
In an earlier series, Crypto-Powered, we laid out arguments for why crypto-native companies have a huge edge in the market. When you consider both the broad spectrum of financial use-cases and the enormous value unlocked through these DeFi protocols, you can see just how big of an unfair advantage blockchain tech becomes for companies who truly understand and leverage it. Traditional banks and fintech unicorns simply won’t be able to keep up.
The power players of consumer finance in the 21st century will be crypto-native companies who build with blockchain technology at their core.The crypto landscape is still nascent. We’re still very much in the fragmented, unbundled phase of the industry lifecycle. Beyond what Genesis Block is doing, there are signs of other companies slowly starting to bundle financial services into what could be an all-in-one bank replacement.
So the key question that this series hopes to answer:
Which crypto-native company will successfully become the bank of the future?We obviously think Genesis Block is well-positioned to win. But we certainly aren’t the only game in town. In this series, we’ll be doing an analysis of who is most capable of thwarting our efforts. We’ll look at categories like crypto exchanges, crypto wallets, centralized lending & borrowing services, and crypto debit card companies. Each category will have its own dedicated post.
Today we’re analyzing big crypto exchanges. The two companies we’ll focus on today are Coinbase (biggest American exchange) and Binance (biggest global exchange). They are the top two exchanges in terms of Bitcoin trading volume. They are in pole position to winning this market — they have a huge existing userbase and strong financial resources.
Will Coinbase or Binance become the bank of the future? Can their early success propel them to winning the broader consumer finance market? Is their growth too far ahead for anyone else to catch up? Let’s dive in.
BinanceThe most formidable exchange on the global stage is Binance (Crunchbase). All signs suggest they have significantly more users and a stronger balance sheet than Coinbase. No other exchange is executing as aggressively and relentlessly as Binance is. The cadence at which they are shipping and launching new products is nothing short of impressive. As Tushar Jain from Multicoin argues, Binance is Blitzscaling.
Here are some of the products that they’ve launched in the last 18 months. Only a few are announced but still pre-launch.
Can they create a cohesive & united product experience?
Binance WeaknessesBinance is strong, but they do have a few major weaknesses that could slow them down.
Binance Wrap UpI don’t believe Binance is likely to succeed with a homegrown product aimed at the consumer finance market. Their current product — which is focused heavily on professional traders and speculators — is unlikely to become the bank of the future. If they wanted to enter the broader consumer market, I believe it’s much more likely that they will acquire a company that is getting early traction. They are not afraid to make acquisitions (Trust, JEX, WazirX, DappReview, BxB, CoinMarketCap, Swipe).
However, never count CZ out. He is a hustler. Binance is executing so aggressively and relentlessly that they will always be on the shortlist of major contenders.
CoinbaseThe crypto-native company that I believe is more likely to become the bank of the future is Coinbase (crunchbase). Their dominance in America could serve as a springboard to winning the West (Binance has a stronger foothold in Asia). Coinbase has more than 30M users. Their exchange business is a money-printing machine. They have a solid reputation as it relates to compliance and working with regulators. Their CEO is a longtime member of the crypto community. They are rumored to be going public soon.
Coinbase StrengthsLet’s look at what makes them strong and a likely contender for winning the broader consumer finance market.
Coinbase WeaknessesLet’s now look at some things that could hold them back.
Coinbase Wrap UpAt Genesis Block, we‘re proud to be working with Coinbase. They are a fantastic company. However, I don’t believe that they’ll succeed in building their own product for the broader consumer finance market. While they have incredible design, there are no signs that they are focused on or capable of internally building this type of product.
Similar to Binance, I think it’s far more likely that Coinbase acquires a promising young startup with strong growth.
Honorable MentionsOther US-based exchanges worth mentioning are Kraken, Gemini, and Bittrex. So far we’ve seen very few signs that any of them will aggressively attack broader consumer finance. Most are going in the way of Binance — listing more assets and adding more pro tools like margin and futures trading. And many, like Coinbase, are trying to attract more institutional customers. For example, Gemini with their custody product.
Wrap UpCoinbase and Binance have huge war chests and massive reach. For that alone, they should always be considered threats to Genesis Block. However, their products are very, very different than the product we’re building. And their approach is very different as well. They are trying to educate and onboard people into crypto. At Genesis Block, we believe the masses shouldn’t need to know or care about it. We did an entire series about this, Spreading Crypto.
Most everyone needs banking — whether it be to borrow, spend, invest, earn interest, etc. Not everyone needs a crypto exchange. For non-crypto consumers (the mass market), the differences between a bank and a crypto exchange are immense. Companies like Binance and Coinbase make a lot of money on their crypto exchange business. It would be really difficult, gutsy, and risky for any of them to completely change their narrative, messaging, and product to focus on the broader consumer market. I don’t believe they would ever risk biting the hand that feeds them.
In summary, as it relates to a digital bank aimed at the mass market, I believe both Coinbase and Binance are much more likely to acquire a startup in this space than they are to build it themselves. And I think they would want to keep the brand/product distinct and separate from their core crypto exchange business.
So back to the original question, is Coinbase and Binance a threat to Genesis Block? Not really. Not today. But they could be, and for that, we want to stay close to them.
