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.

Ren allows the free movement of value between all blockchains and transfer of tokens in zero-knowledge. Unlocking new liquidity and resources to power a new wave of value in the open finance movement. With Ren all decentralized applications can run in secret, preserving the privacy of all users and data. (Renproject.io)
Ren is the evolution of the technology that underpins RepublicProtocol, in its most useful and general form. It becomes something much bigger than Republic Protocol and will empower developers to build decentralized and trustless applications, with a distinct focus on financial applications. Using our own newly developed secure multiparty computation protocol, all DeFi applications will have access to interoperable liquidity and run in complete secrecy. (Ren —The Evolution of a Protocol)💡 To dumb it down a bit, Ren is the organization's name, REN is the ERC-20 based token, and RenVM is Ren’s core product.
RenVM is replicated over thousands of machines that work together to power it, contributing their network bandwidth, their computational power, and their storage capacity. These machines are known as Darknodes.Ok so now we know what a Darknode is but what is REN Tokens used for?
Darknodes communicate with other Darknodes around the world to keep RenVM running. Without them, there is no virtual machine upon which Ren can exist. RenVM uses Byzantine Fault Tolerant consensus algorithms and secure multiparty computations so that Darknodes can be operated by anyone without needing to trust them. This is what makes RenVM — and by extension, Ren itself — decentralized, trustless, and private. (Ren Documentation)
The decentralized network of Darknodes is permissionless, but to prevent the forging of a large number of identities a good behavior a bond of 100,000 REN tokens is required in order to register and run a Darknode. This prevents malicious adversaries from running an unbounded number of Darknodes and overwhelming the network with misbehaving Darknodes. (Ren Documentation)As stated, to run a Darknode you'll need 100,000 REN. You can liken this to Proof of Stake (PoS) systems in which you stake a certain currency to encourage honest behavior in block production. The benefits of running a Darknode is you will be paid transaction fees. Initially, the fees were paid in REN tokens but now Darknode operators can be paid other cryptocurrencies such as BTC, ETH, ZEC, and other ERC20 tokens.
The Ren Alliance is a consortium of DeFi companies and/or projects that are helping secure, develop, and utilize RenVM. (Introducing the Ren Alliance)Also, Important to note is Ren has top tier investors in the likes of FGB Capital, Polychain Capital, and Kenetic Capital. But its headlining investor is crypto giant Huobi, which this past July launched its Huobi Cloud platform for OTC desks. Work is being done and a lot of progress is being made.
The blockchain-based networks are being built to offer specific capabilities such as making payments, storing and trading assets and others. However, these capabilities are being offered in isolation where these networks don’t talk to each other and cannot share data. Existing centralized systems have evolved to offer the same capabilities in a more integrated way where these systems are able to run end to end transactions seamlessly making it easier for users.The cryptocurrency space is pretty fragmented at times. There also is a bunch of tribalism. It can be a bit annoying. One coin makes massive efforts over here and another coin is making massive efforts over there. What if we could combine the efforts into one big force of nature? I think we can take over the world. Which, would be, huge.
If blockchain-based networks have to make a strong case for their adoption, they have to be able to work with each other and offer this seamless integration of capabilities to their users.
Strong interoperability would give users a much more useful, user-friendly experience. With this interoperability, users will be able to experience the seamless integration of capabilities being offered by the blockchain-based networks. If we have to hypothesize an example, it would look something like this – User will be able to tokenize the asset (e.g. artwork) over Ethereum based DApp, will be able to transfer the tokenized asset to another address over Cardano, and pay any corresponding transaction fees over the bitcoin network.

tBTC is a trustlessly Bitcoin-backed ERC-20 token.https://github.com/keep-network/tbtc
The goal of the project is to provide a stronger 2-way peg than federated sidechains like Liquid, expanding use cases possible via today’s Bitcoin network, while bringing superior money to other chains.
This repo contains the Solidity smart contracts and specification.
tbtc.js provides JS bindings to the tBTC system. The tBTC system is a bonded, multi-federated peg made up of many deposits backed by single-use BTC wallets to enable their value’s corresponding usage on the Ethereum chain, primarily through the minting of a TBTC ERC20 token whose supply is guaranteed to be backed by at least 1 BTC per TBTC in circulation.finally this is the best:
2020-04-01 tBTC incorporates novel design features that carry important implications for users. This piece explains four of these: TDT receipts, multiple lot sizes, Keep's random beacon, and threshold signatures.also this paragraph addresses creating wallets with the created tokens
TBTC Deposit Token (TDT) The TBTC Deposit Token (TDT) is a non-fungible token that is minted when a user requests a deposit. A TDT is a non-fungible ERC-721 token that serves as a counterpart to TBTC. It represents a claim to a deposit's underlying UTXO on the Bitcoin blockchain.
TBTC deposits can be locked or unlocked. A locked deposit can only be redeemed by the deposit owner with the corresponding TDT. Each TDT is unique to the deposit that mints it and carries the exclusive right for up to a 6 month term to redeem the deposit.
Random Beacon for Signer Selectionmy take away from this is that by using side chains that a trustless, not fedeared like liquid bitcoin sidechains sold by blockstream. it uses NFT erc-721 tokens as representation of the bitccoin UTXO from the bitcoin blockchain, store it in a wallet and mint it into tBTC. given this is all smart contracts generating wallets and minting the tBTC, it does away with the need of a centralised party to provide the funds of BTC to create a wrapped erc20 version on ethereum and so should be trustles.
The Keep network requires a trusted source of randomness to select tBTC signers. This takes the form of a BLS Threshold Relay.
When a request comes in to create a signing group, the tBTC system uses a random seed from a secure decentralized random beacon to randomly select signing group members from the eligible pool of signers. These signers coordinate a distributed key generation protocol that results in a public ECDSA key for the group, which is used to produce a wallet address that is then published to the host chain. This completes the signer selection phase.
I talked to James a bit about tBTC in Osaka, so I have a vague idea of how it works, so I might be able to explain it in a somewhat coherent way.
Basically, the magic here is they reimplemented Bitcoin's SPV as an Ethereum smart contract, effectively letting them query the current state of the Bitcoin network, including validity of payments, directly in contract. Using this, they built an auction system where people can at any time claim ETH by paying BTC, or claim BTC by paying ETH. By design the spread is wide, so this isn't actually intended to be a high volume exchange, but what you do get is a pretty good price oracle.
From the price oracle, I think there were doing some Maker style CDPs or something, where people could lock up their BTC on the Bitcoin network to redeem tBTC, and any of the locked BTC could be reclaimed by burning tBTC or something.
Sorry it's not a complete picture of what's going on, but I think that's the general gist of what they're doing.
MintCoin (MINT) is a cryptocurrency. MintCoin has a current supply of 24,947,260,807.982. The last known price of MintCoin is $0.000092 USD and is up 11.42% over the last 24 hours. It is currently trading on 1 active market(s) with $0.091686 traded over the last 24 hours. The Bitminter mining pool will shut down mining activities on 2020-07-01. The website will stay up until 2021-06-01 so you can cash out any crypto currency on your account. It is unfortunate to have to shut down after 9 years of mining. However, to keep going would not be fair to the few miners we have left in the pool. CGMiner is an open source C-based multi-threaded multi-pool ASIC and FPGA and it is among the most used cryptocurrency miners with support and binaries for RPi, OpenWrt routers. Grin is an experimental coin: use at your own risk! Grinmint does not guarantee any return on mining time or hashpower. You are strongly encouraged to move your rewards off the pool as often as possible into a wallet that you control. Instead, the pool takes a percentage of the Bitcoin mined (typically between 1 and 2 percent). BitMinter, CK Pool, and Slush Pool are some popular, successful, and well-established mining pools. Without a mining pool, you would have to mine potentially for years before you'd see any profit.
