A whirlwind tour of Defi, paying close attention to protocols that we’re leveraging at Genesis Block.submitted by mickhagen to genesisblockhq [link] [comments]
This is the third post of Crypto-Powered — a new series that examines what it means for Genesis Block to be a digital bank that’s powered by crypto, blockchain, and decentralized protocols.
Last week we explored how building on legacy finance is a fool’s errand. The future of money belongs to those who build with crypto and blockchain at their core. We also started down the crypto rabbit hole, introducing Bitcoin, Ethereum, and DeFi (decentralized finance). That post is required reading if you hope to glean any value from the rest of this series.
97% of all activity on Ethereum in the last quarter has been DeFi-related. The total value sitting inside DeFi protocols is roughly $2B — double what it was a month ago. The explosive growth cannot be ignored. All signs suggest that Ethereum & DeFi are a Match Made in Heaven, and both on their way to finding strong product/market fit.
So in this post, we’re doing a whirlwind tour of DeFi. We look at specific examples and use-cases already in the wild and seeing strong growth. And we pay close attention to protocols that Genesis Block is integrating with. Alright, let’s dive in.
StablecoinsStablecoins are exactly what they sound like: cryptocurrencies that are stable. They are not meant to be volatile (like Bitcoin). These assets attempt to peg their price to some external reference (eg. USD or Gold). A non-volatile crypto asset can be incredibly useful for things like merchant payments, cross-border transfers, or storing wealth — becoming your own bank but without the stress of constant price volatility.
There are major governments and central banks that are experimenting with or soon launching their own stablecoins like China with their digital yuan and the US Federal Reserve with their digital dollar. There are also major corporations working in this area like JP Morgan with their JPM Coin, and of course Facebook with their Libra Project.
Stablecoin activity has grown 800% in the last year, with $290B of transaction volume (funds moving on-chain).The most popular USD-pegged stablecoins include:
tablecoins are playing an increasingly important role in the world of DeFi. In a way, they serve as common pipes & bridges between the various protocols.https://preview.redd.it/v9ki2qro12b51.png?width=700&format=png&auto=webp&s=dbf591b122fc4b3d83b381389145b88e2505b51d
Lending & BorrowingThree of the top five DeFi protocols relate to lending & borrowing. These popular lending protocols look very similar to traditional money markets. Users who want to earn interest/yield can deposit (lend) their funds into a pool of liquidity. Because it behaves similarly to traditional money markets, their funds are not locked, they can withdraw at any time. It’s highly liquid.
Borrowers can tap into this pool of liquidity and take out loans. Interest rates depend on the utilization rate of the pool — how much of the deposits in the pool have already been borrowed. Supply & demand. Thus, interest rates are variable and borrowers can pay their loans back at any time.
So, who decides how much a borrower can take? What’s the process like? Are there credit checks? How is credit-worthiness determined?These protocols are decentralized, borderless, permissionless. The people participating in these markets are from all over the world. There is no simple way to verify identity or check credit history. So none of that happens.
Credit-worthiness is determined simply by how much crypto collateral the borrower puts into the protocol. For example, if a user wants to borrow $5k of USDC, then they’ll need to deposit $10k of BTC or ETH. The exact amount of collateral depends on the rules of the protocol — usually the more liquid the collateral asset, the more borrowing power the user can receive.
The most prominent lending protocols include Compound, Aave, Maker, and Atomic Loans. Recently, Compound has seen meteoric growth with the introduction of their COMP token — a token used to incentivize and reward participants of the protocol. There’s almost $1B in outstanding debt in the Compound protocol. Mainframe is also working on an exciting protocol in this area and the latest iteration of their white paper should be coming out soon.
There is very little economic risk to these protocols because all loans are overcollateralized.I repeat, all loans are overcollateralized. If the value of the collateral depreciates significantly due to price volatility, there are sophisticated liquidation systems to ensure the loan always gets paid back.
InvestmentsBuying, selling, and trading crypto assets is certainly one form of investing (though not for the faint of heart). But there are now DeFi protocols to facilitate making and managing traditional-style investments.
Through DeFi, you can invest in Gold. You can invest in stocks like Amazon and Apple. You can short Tesla. You can access the S&P 500. This is done through crypto-based synthetics — which gives users exposure to assets without needing to hold or own the underlying asset. This is all possible with protocols like UMA, Synthetix, or Market protocol.
Maybe your style of investing is more passive. With PoolTogether , you can participate in a no-loss lottery.
Maybe you’re an advanced trader and want to trade options or futures. You can do that with DeFi protocols like Convexity, Futureswap, and dYdX. Maybe you live on the wild side and trade on margin or leverage, you can do that with protocols like Fulcrum, Nuo, and DDEX. Or maybe you’re a degenerate gambler and want to bet against Trump in the upcoming election, you can do that on Augur.
And there are plenty of DeFi protocols to help with crypto investing. You could use Set Protocol if you need automated trading strategies. You could use Melonport if you’re an asset manager. You could use Balancer to automatically rebalance your portfolio.
With as little as $1, people all over the world can have access to the same investment opportunities and tools that used to be reserved for only the wealthy, or those lucky enough to be born in the right country.
You can start to imagine how services like Etrade, TD Ameritrade, Schwab, and even Robinhood could be massively disrupted by a crypto-native company that builds with these types of protocols at their foundation.https://preview.redd.it/agco8msx12b51.png?width=700&format=png&auto=webp&s=3bbb595f9ecc84758d276dbf82bc5ddd9e329ff8
InsuranceAs mentioned in our previous post, there are near-infinite applications one can build on Ethereum. As a result, sometimes the code doesn’t work as expected. Bugs get through, it breaks. We’re still early in our industry. The tools, frameworks, and best practices are all still being established. Things can go wrong.
Sometimes the application just gets in a weird or bad state where funds can’t be recovered — like with what happened with Parity where $280M got frozen (yes, I lost some money in that). Sometimes, there are hackers who discover a vulnerability in the code and maliciously steal funds — like how dForce lost $25M a few months ago, or how The DAO lost $50M a few years ago. And sometimes the system works as designed, but the economic model behind it is flawed, so a clever user takes advantage of the system— like what recently happened with Balancer where they lost $500k.
There are a lot of risks when interacting with smart contracts and decentralized applications — especially for ones that haven’t stood the test of time. This is why insurance is such an important development in DeFi.
Insurance will be an essential component in helping this technology reach the masses.Two protocols that are leading the way on DeFi insurance are Nexus Mutual and Opyn. Though they are both still just getting started, many people are already using them. And we’re excited to start working with them at Genesis Block.
Exchanges & LiquidityDecentralized Exchanges (DEX) were one of the first and most developed categories in DeFi. A DEX allows a user to easily exchange one crypto asset for another crypto asset — but without needing to sign up for an account, verify identity, etc. It’s all via decentralized protocols.
Within the first 5 months of 2020, the top 7 DEX already achieved the 2019 trading volume. That was $2.5B. DeFi is fueling a lot of this growth.
There are many different flavors of DEX. Some of the early ones included 0x, IDEX, and EtherDelta — all of which had a traditional order book model where buyers are matched with sellers.
Another flavor is the pooled liquidity approach where the price is determined algorithmically based on how much liquidity there is and how much the user wants to buy. This is known as an AMM (Automated Market Maker) — Uniswap and Bancor were early leaders here. Though lately, Balancer has seen incredible growth due mostly to their strong incentives for participation — similar to Compound.
There are some DEXs that are more specialized — for example, Curve and mStable focus mostly only stablecoins. Because of the proliferation of these decentralized exchanges, there are now aggregators that combine and connect the liquidity of many sources. Those include Kyber, Totle, 1Inch, and Dex.ag.
These decentralized exchanges are becoming more and more connected to DeFi because they provide an opportunity for yield and earning interest.Users can earn passive income by supplying liquidity to these markets. It usually comes in the form of sharing transaction fee revenue (Uniswap) or token rewards (Balancer).
PaymentsAs it relates to making payments, much of the world is still stuck on plastic cards. We’re grateful to partner with Visa and launch the Genesis Block debit card… but we still don’t believe that's the future of payments. We see that as an important bridge between the past (legacy finance) and the future (crypto).
Our first post in this series shared more on why legacy finance is broken. We talked about the countless unnecessary middle-men on every card swipe (merchant, acquiring bank, processor, card network, issuing bank). We talked about the slow settlement times.
The future of payments will be much better. Yes, it’ll be from a mobile phone and the user experience will be similar to ApplePay (NFC) or WePay (QR Code).
But more importantly, the underlying assets being moved/exchanged will all be crypto — digital, permissionless, and open source.Someone making a payment at the grocery store check-out line will be able to open up Genesis Block, use contactless tech or scan a QR code, and instantly pay for their goods. All using crypto. Likely a stablecoin. Settlement will be instant. All the middlemen getting their pound of flesh will be disintermediated. The merchant can make more and the user can spend less. Blockchain FTW!
Now let’s talk about a few projects working in this area. The xDai Burner Wallet experience was incredible at the ETHDenver event a few years ago, but that speed came at the expense of full decentralization (can it be censored or shut down?). Of course, Facebook’s Libra wants to become the new standard for global payments, but many are afraid to give Facebook that much control (newsflash: it isn’t very decentralized).
Bitcoin is decentralized… but it’s slow and volatile. There are strong projects like Lightning Network (Zap example) that are still trying to make it happen. Projects like Connext and OmiseGo are trying to help bring payments to Ethereum. The Flexa project is leveraging the gift card rails, which is a nice hack to leverage existing pipes. And if ETH 2.0 is as fast as they say it will be, then the future of payments could just be a stablecoin like DAI (a token on Ethereum).
In a way, being able to spend crypto on daily expenses is the holy grail of use-cases. It’s still early. It hasn’t yet been solved. But once we achieve this, then we can ultimately and finally say goodbye to the legacy banking & finance world. Employees can be paid in crypto. Employees can spend in crypto. It changes everything.
Legacy finance is hanging on by a thread, and it’s this use-case that they are still clinging to. Once solved, DeFi domination will be complete.https://preview.redd.it/svft1ce422b51.png?width=700&format=png&auto=webp&s=9a6afc9e9339a3fec29ee2ae743c07c3042ea4ce
Impact on Genesis BlockAt Genesis Block, we’re excited to leverage these protocols and take this incredible technology to the world. Many of these protocols are already deeply integrated with our product. In fact, many are essential. The masses won’t know (or care about) what Tether, USDC, or DAI is. They think in dollars, euros, pounds and pesos. So while the user sees their local currency in the app, the underlying technology is all leveraging stablecoins. It’s all on “crypto rails.”
When users deposit assets into their Genesis Block account, they expect to earn interest. They expect that money to grow. We leverage many of these low-risk lending/exchange DeFi protocols. We lend into decentralized money markets like Compound — where all loans are overcollateralized. Or we supply liquidity to AMM exchanges like Balancer. This allows us to earn interest and generate yield for our depositors. We’re the experts so our users don’t need to be.
We haven’t yet integrated with any of the insurance or investment protocols — but we certainly plan on it. Our infrastructure is built with blockchain technology at the heart and our system is extensible — we’re ready to add assets and protocols when we feel they are ready, safe, secure, and stable. Many of these protocols are still in the experimental phase. It’s still early.
At Genesis Block we’re excited to continue to be at the frontlines of this incredible, innovative, technological revolution called DeFi.---
None of these powerful DeFi protocols will be replacing Robinhood, SoFi, or Venmo anytime soon. They never will. They aren’t meant to! We’ve discussed this before, these are low-level protocols that need killer applications, like Genesis Block.
So now that we’ve gone a little deeper down the rabbit hole and we’ve done this whirlwind tour of DeFi, the natural next question is: why?
Why does any of it matter?Most of these financial services that DeFi offers already exist in the real world. So why does it need to be on a blockchain? Why does it need to be decentralized? What new value is unlocked? Next post, we answer these important questions.

It’s a balmy 80 degrees on a mid-December day in Singapore, and something is puzzling Allen Day, a 41-year-old data scientist. Using the tools he has developed at Google, he can see a mysterious concerted usage of artificial intelligence on the blockchain for Ethereum. Ether is the world’s third-largest cryptocurrency (after bitcoin and XRP), and it still sports a market cap of some $11 billion despite losing 83% of its value in 2018. Peering into its blockchain—the distributed database of transactions underpinning the cryptocurrency—Day detects a “whole bunch” of “autonomous agents” moving funds around “in an automated fashion.” While he doesn’t yet know who has created the AI, he suspects they could be the agents of cryptocurrency exchanges trading among themselves in order to artificially inflate ether’s price.submitted by dForceProtocol to u/dForceProtocol [link] [comments]
“It’s not really just single agents doing things on their own,” Day says from Google’s Asia-Pacific headquarters. “They’re forming with other agents to have some larger group effect.”
Day’s official title is senior developer advocate for Google Cloud, but he describes his role as “customer zero” for the company’s cloud computing efforts. As such it’s his job to anticipate demand before a product even exists, and he thinks making the blockchain more accessible is the next big thing. Just as Google enabled (and ultimately profited) from making the internet more usable 20 years ago, its next billions may come from shining a bright light on blockchains. If Day is successful, the world will know whether blockchain’s real usage is living up to its hype.
Danish researcher Thomas Silkjaer is using Google's BigQuery to map publicly available information about XRP cryptocurrency addresses. The craters represent some of cryptocurrency's largest exchanges.
Last year Day and a small team of open-source developers quietly began loading data for the entire Bitcoin and Ethereum blockchains into Google’s big-data analytics platform, BigQuery. Then, with the help of lead developer Evgeny Medvedev, he created a suite of sophisticated software to search the data.
In spite of a total lack of publicity, word of the project spread quickly among crypto-minded coders. In the past year, more than 500 projects were created using the new tools, trying to do everything from predicting the price of bitcoin to analyzing wealth disparity among ether holders.
When it comes to cloud computing, Google is far behind Amazon and Microsoft. Last year Google pocketed an estimated $3 billion in revenue from cloud services. Amazon and Microsoft, meanwhile, generated about $27 billion and $10 billion, respectively.
Day is hoping that his project, known as Blockchain ETL (extract, transform, load), will help even the playing field. But even here Google is trying to catch up. Amazon entered blockchain in a big way in 2018 with a suite of tools for building and managing distributed ledgers. Microsoft got into the space in 2015, when it released tools for Ethereum’s blockchain. It now hosts a range of services as part of its Azure Blockchain Workbench. But while Amazon and Microsoft are focusing on making it easier to build blockchain apps, Day is focusing on exposing how blockchains are actually being used, and by whom.
“In the future, moving more economic activity on chain won’t just require a consensus level of trust,” says Day, referring to the core validating mechanism of blockchain technology. “It will require having some trust in knowing about who it is you’re actually interacting with.” In other words, if blockchain is to go mainstream, some of its beloved anonymity features will have to be abandoned.
A native of Placer County, California, Day got his first computer at the age of 5 and a few years later started writing simple programs. A fascination with volcanoes and dinosaurs turned his interest to life sciences, and he ultimately graduated from the University of Oregon with a dual degree in biology and Mandarin in 2000. From there he headed to UCLA to pursue a doctorate in human genetics and helped build a computer program to browse the genome.
It was at UCLA where Day began relying on distributed computing, a concept that is core to blockchains, which store their data on a large network of individual computers. In the early 2000s Day needed to analyze the massive amounts of data that make up the human genome. To solve this problem he hooked many small computers together, vastly increasing their power.
“Distributed-systems technology has been in my tool kit for a while,” Day says. “I could see there were interesting characteristics of blockchains that could run a global supercomputer.”
Hired in 2016 to work in the health and bioinformatics areas of Google, Day segued to blockchains, the hottest distributed-computing effort on the planet. But the talents he had honed—sequencing genomes for infectious diseases in real time and using AI to increase rice yields—were not easily applied to decoding blockchain.
Before Day and Medvedev released their tools, just searching a blockchain required specialized software called “block explorers,” which let users hunt only for specific transactions, each labeled with a unique tangle of 26-plus alphanumeric characters. Google’s Blockchain ETL, by contrast, lets users make more generalized searches of entire ecosystems of transactions.
To demonstrate how customers could use Blockchain ETL to make improvements to the crypto economy, Day has used his tools to examine the so-called hard fork, or an irrevocable split in a blockchain database, that created a new cryptocurrency—bitcoin cash—from bitcoin in the summer of 2017.

This particular split was the result of a Hatfield and McCoy “war” within the bitcoin community between a group who wanted to leave bitcoin as it was and another who wanted to develop a currency that, like cash, was cheaper and faster to use for small payments. Using Google’s BigQuery, Day discovered that bitcoin cash, rather than increasing so-called micro-transactions, as the defecting developers claimed, was actually being hoarded among big holders of bitcoin cash. “I’m very interested to quantify what’s happening so that we can see where the legitimate use cases are for blockchain,” Day says. “Then we can move to the next use case and develop out what these technologies are really appropriate for.”
Day’s work is inspiring others. Tomasz Kolinko is a Warsaw-based programmer and the creator of a service that analyzes smart contracts, a feature of certain blockchains that is designed to transparently enforce contractual obligations like collateralized loans but with less reliance on third parties, like lawyers. Kolinko was frustrated with his blockchain queries.
In December, Kolinko met Day at a hackathon in Singapore. Within a month of the meeting, Kolinko was using Google’s tools to search for a smart contract feature called a “selfdestruct,” designed to limit a contract’s life span. Using his own software in conjunction with Day’s, Kolinko took 23 seconds to search 1.2 million smart contracts—something that would have taken hours before. The result: Almost 700 of them had left open a selfdestruct feature that would let anyone instantly kill the smart contract, whether that person was authorized or not. “In the past you couldn’t just easily check all the contracts that were using it,” Kolinko says. “This tool is both the most scary and most inspiring I’ve ever built.”
Day is now expanding beyond bitcoin and ethereum. Litecoin, zcash, dash, bitcoin cash, ethereum classic and dogecoin are being added to BigQuery. Independent developers are loading their own crypto data sets on Google. Last August, a Dutch developer named Wietse Wind uploaded the entire 400 gigabytes of transaction data from Ripple’s XRP blockchain, another popular cryptocurrency, into BigQuery. Wind’s data, which he updates every 15 minutes, prompted a Danish designer named Thomas Silkjaer to create a heat map of crypto flows. The resulting colorful orb reveals at a glance more than a million crypto wallets, including big exchanges like Binance and London’s crypto debit card startup Wirex, which are neck deep in XRP transactions.
“Google has been a bit of a sleeping giant in blockchain,” says BlockApps CEO Kieren James-Lubin, who is partnering with Google to sell enterprise blockchain apps. In addition to Day’s work, Google has filed numerous patents related to the blockchain, including one in 2018 to use a “lattice” of interoperating blockchains to increase security, a big deal in a world where untold millions of crypto have been stolen by hackers. The company is also pushing its developers to build apps on the Ethereum blockchain, and Google’s venture arm, GV, has made a number of significant investments in crypto startups.
The giant, it seems, is waking up.
