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.

Over the course of mere months, the DeFi space has grown to the tune of billions in 2020. While DeFi has earned its title as the next hottest crypto trend, its popularity has shown to be a double-edged sword. Reports of scams and “rug pulls” have volleyed into crypto news outlets, social media, and discussion groups, damaging the reputation of the DeFi space.
DeFi is unique in that the tenets of trust and decentralization has normalized the practice of anonymity to the point where nearly every single DeFi team launches anonymously. While the freedom to create DeFi tools does support the notion that anyone should be able to create an honest financial protocol for the goodwill of the people, the opposite effect often occurs. If the past few months has proven anything, it’s that the normalization of anonymity has acted as both the greatest weapon and the greatest defence for fraudulent actors and dishonest entities. Because of this, DeFi is often seen as a free-for-all minefield as countless exit scams and “rugpulls” have become the norm. Having this as an accepted vice of DeFi shouldn’t mean investors should normalize risk of losses. It should inspire projects to set a higher standard in the DeFi space.
We are excited to announce that the YFDAI team has taken the tenets of decentralized finance and expanded on them. As a DeFi protocol, we champion decentralization and the collective action of the community to pave the road towards true transparency and security for all. After countless hours of legal counseling, we’re proud to announce that we will be among the very few DeFi projects to go public and among the first to set a new precedent for the DeFi space.
Say hello to the YFDAI team.

Now that the team identities have been released this dispels the “Elephant in the room”. The fact that the team chose to become non-anon opens up many doors that would otherwise be closed. The specifics of those opportunities will be made clear in the upcoming whitepaper and future announcements.
Even though the names and faces of the founders behind the project have been revealed, please note that there are many people who are working on the YFDAI project on a contractual basis and volunteer basis who have not been included in the disclosure. There are experts and advisors in the fields of business development, economics, law, and other areas vital to any business that play a major role in the success of YFDAI and who share the vision of the founders to clean up the DeFi space and offer a safe, reliable, and secure suite of DeFi products to the public.
While the team behind a crypto project is vital, the ultimate success of any DeFi project relies on the technology, the code, and the community. YFDAI’s technology and code have been designed to be bulletproof in order to maximize the safety and security for the end user. In the not too distant future, YFDAI’s business model envisions the everyday decisions to ultimately be made by you, the community, by way of the DAO as governance is turned over to the token holders.
To ensure we are operating as securely and compliantly as possible YFDAI has been incorporated as a Technology business in Singapore:
Company Name — Tejster Technologies PTE. LTD. Registration No — 202031933C Address — 50,Raffles Place,#37–00,Singapore Land Tower, Singapore (048623)
To finalise the compliance aspect YFDAI is in the process of obtaining full Financial Services regulation by means of receiving compliance and registration in the Republic of Estonia.
This will be a two stage process with an initial Virtual Currency Exchange and E-Wallet licence currently being sought. YDFAI’s legal representatives have moved this to an advanced stage and expect this to be finalized in Q4 2020. It is at this point that the team shall resume their full job titles and the term “Volunteer” will no longer be required.
The licenses will open up a plethora of opportunities which will be fully detailed in our soon to be released whitepaper and will also provide YFDAI with a level of accreditation that will provide users with full peace of mind.
Once YFDAI secures the Financial Services accreditation listed above, YFDAI will have full insurance coverage of the project’s financial holdings and transactions, including project wallets and user funds.
Thank you for your support and we look forward to setting a new standard of self regulation that will revolutionize the DeFI arena and level the playing field for all participants while minimizing the fraud and desecration of the bad actors who have infiltrated the DeFi space.

How Decentralized Finance Came to BeDecentralized Finance (DeFi) can be rightfully considered a third revolution in the crypto space. If you wonder what the first two are, these are the invention of blockchain itself along with the technology’s firstborn, Bitcoin, and the inception of the smart contract technology. Just like blockchain provides the basis for smart contracts, the latter give rise to DeFi. It is often said that smart contracts are poised to revolutionize the ways both humans and organizations interact in their contractual relationships. In this sense, DeFi is the stage where these relationships are set to emerge and develop. With a bigger picture in mind, it is the world that the blockchain technology lays the foundation for, while smart contracts help to build it. Why we need DeFi, how it is possible, what makes it tick and click are the main themes of this article.
But seriously, why do we need it?As most financial services in existence today are provided by or involve third parties, for example, banks, exchanges, investment companies, insurance agencies etc, DeFi is an attempt to build an alternative environment, an ecosystem of applications offering the same set of services but now powered by public blockchain networks in a decentralized, transparent and permissionless way. By and large, the basic idea that guides DeFi is essentially the same ethos that drives innovation with crypto as such, but at an entirely different level.
Just like cryptocurrencies try to wrest the state supremacy over money from the hands of rogue governments and central banks, DeFi takes it further and aims higher. With DeFi, it is no longer a matter of creating a coin in an effort to replace fiat money, which mostly doesn’t work anyway. However, building a whole new domain of financial services available fairly and squarely to anyone, with full control over the assets but without corrupt governments and greedy intermediaries sticking around, may pan out better after all.
So, answering the question posed at the beginning of this section, we need DeFi for basically the same reasons we need cryptocurrencies. Or, put differently, if we need cryptocurrencies, an assumption that has been proved indisputable, it is inevitable as well that we will sooner or later become interested in decentralized financial services powered by these cryptocurrencies through smart contract blockchains. We can’t just create Bitcoin and say that’ll do. It is a natural development, a Maslow’s hierarchy of needs, in a sense.
How is it ever possible?As mentioned in the introduction, DeFi emerges thanks to smart contract tech and decentralized applications (or simply dApps) running them. So how does it work in practice? To better understand the idea, let’s take a closer look at a relatively simple example of a decentralized crypto-backed stablecoin which can be created through a smart contract. Stablecoins are coins whose value is pegged to a stable asset such as a commodity like gold or a fiat currency like the US dollar.
There are a few different types of stablecoins that exist in the wild. For the purpose of this exposition, we are interested in crypto-backed stablecoins. Like stablecoins collateralized by fiat, these stablecoins use cryptocurrencies as collateral. However, the key difference is that a fiat-based stablecoin is pegged to the fiat currency which is backing it up. Kinda obvious. A crypto-backed stablecoin, on the other hand, is pegged to one asset, say, the American dollar, but backed up by a completely different one, for example, Ether. Things get tricky.
A crypto-collateralized stablecoin is possible through the magic and the beauty of the smart contract governing it. If the price of such a stablecoin rises above its peg, or parity, you can create more stablecoins and sell them at a premium. If the price of the stablecoin falls below parity, you can buy stablecoins and liquidate them at a discount. If the collateral itself crashes, undercollateralized stablecoins will be liquidated with their collateral now backing up fewer stablecoins. As a result, the price always gets pushed back to parity.
And all this rather complicated stuff is done on the blockchain in a decentralized and automatic fashion with no banks or other third parties involved. Consequently, more services are easily possible too. And quite a few at that.
Okay, what decentralized financial services are available?Well, one such service we have just described above. Cryptocurrencies are infamous for being extremely volatile, and stablecoins are designed to deal with this issue. There are many stablecoins out there like Tether, TrueUSD, or Gemini Coin, but they are all based on trusting third parties. Easily one of the best known crypto-backed stablecoins is MakerDAO’s DAI, which is pegged against the US dollar with a basket of crypto-assets as collateral in a truly decentralized and trustless way, that is, a blockchain way.
Crypto-based stablecoins can be used on their own by offering a hedge against the price volatility of such popular cryptocurrencies as Ether or Bitcoin. Aside from that, they are also instrumental in other DeFi services, for example, in decentralized exchanges like IDEX or BiKi.com. With stablecoins, it becomes possible to create fiat trading pairs in addition to crypto ones in entirely decentralized, non-custodial trading environments as opposed to centralized exchanges like Bitfinex or Binance, which are vulnerable to high-profile hacks and personal data leaks.
Unlike MakerDAO, Ampleforth doesn’t strive to create a rock-solid stablecoin. Instead, it comes up with the notion of “adaptive money built on sound economics”, with its mission stretching out as far as to marry “the scarcity of Bitcoin with the elasticity of fiat”. It tries to go beyond the relatively simple concept of a stablecoin and brings forth the idea of elastic money supply that can expand and contract depending on market demands, as well as allow the creation of a valid form of collateral for DeFi based on that idea.
Obviously, DeFi is not just about stablecoins or the financial services using them. Blockchain-based borrowing and lending is another important DeFi arena. With platforms like Compound, dYdX, Dharma, you can deposit your crypto assets to either earn interest on them or use these assets as collateral for borrowing. Smart contracts automatically match borrowers and lenders, offering dynamic interest rates based on supply and demand. And with tools like LoanScan, you can also easily shop around for the best interest rates on the block.
These examples are far from exhaustive, of course, as the space is rapidly expanding and evolving. However, there are some fundamental issues that put grit into the wheels of the DeFi war machine.
So where’s the catch?There are many advantages of DeFi, but to be of any practical use, it needs up-to-date information that would be reliable and authentic. Smart contracts that DeFi is based on are hopelessly on-chain, but the data they need for processing is mostly off-chain. Without a bridge to close this gap between a smart contract and its source of external information, smart contracts are entrapped in closed-off dungeons of their blockchains. To be sure, no crypto-based stablecoin is going to work correctly without a real-time price feed for the assets taken as its collateral and used for maintaining the peg.
To get around this roadblock, a concept of blockchain oracles has been suggested. But as the chain cannot be stronger than its weakest link, blockchain oracles seem to be that weak link in the field of DeFi and beyond as obtaining information in a verifiable way can be an intimidating task. What approaches dApps are taking to procure and verify sources of truth in the external world is the topic of our upcoming article about blockchain oracles. Stay with us and stay tuned!
