EthHub Weekly #110

Curated by Anthony Sassano (@sassal0x) and Eric Conner (@econoar)

🎮 Ready Player Eth2

It was a pretty significant week for eth2 this week as the Prysmatic Labs Topaz testnet went live. This new testnet is running the full mainnet configuration for Phase 0 of eth2. There has been a lot of chatter about what hardware you’ll need to run an eth2 beacon node and validators so I wanted to give a little bit of insight here.

Beacon Nodes are heavyweight nodes (like current eth1 node software) and validators are lightweight. To stake in eth2, you can either spin up your own Beacon Node and point your validators at it or use a third-party one. In either case, you only need one Beacon Node but you will need a separate validator instance for every 32 ETH you plan to stake (remember, validators are lightweight). What this means is that you can run validators on hardware such as Raspberry Pi’s or other mini PC’s but you will need a more beefy system if you want to run your own Beacon Node. Hopefully that explanation provides some clarity!

A fresh new guide was added to EthHub this week that gives a straightforward explanation of ERC20 tokens on Ethereum. Check that out here.

Got ideas for a cool DeFi app but not a developer? Add a comment to this Google doc with your idea and a hacker might just build it at ETHGlobal’s online Hack Money hackathon!

Have a great week everyone!

News of the Week

😬 dForce Loses $25mil in Exploit

dForce, a Multicoin Capital-backed Chinese decentralized finance (DeFi) protocol, has been exploited. 

The total value locked in the dForce ecosystem was down by 100% to $6 over the past 24 hours, per DeFi Pulse data. A day ago, the total value locked in the system was $24.9 million. The Lendf.Me website is no longer accessible.

It is worth noting that in January, Lendf.Me integrated with imBTC, an Ethereum token pegged to BTC. Earlier today, a liquidity pool for imBTC on decentralized exchange Uniswap was exploited, resulting in a loss of around $300,000 worth of tokens. 

The imBTC attack took advantage of the fact that imBTC uses ERC 777 standard, which allows the hacker to continuously call the Uniswap smart contract to withdraw funds before the external balance could be updated. Lendf.Me experienced a similar attack to the imToken one, as transaction records show that the hacker repetitively called Lendf.Me’s withdrawal function to take out imBTC that was supplied to the lending protocol by the hacker in the first place. 

🤔 ‘Black Thursday’ losses spur $28 million class-action lawsuit against Maker Foundation

A proposed class-action lawsuit seeking more than $28 million from the Maker Foundation and several of its affiliates is set to be filed in U.S. federal court, according to documents obtained by The Block.

In a draft complaint, the Maker Foundation – a non-profit organization supporting the development of the MakerDAO decentralized finance (DeFi) protocol – was accused of misrepresenting the protocol’s risks to investors and failing to protect investor interest. 

Specifically, the complaint alleges negligence, intentional misrepresentation and negligent misrepresentation in connection with the claimed losses. The lawsuit does not seem to have been filed in the U.S. District Court for the Northern District of California.

“While misrepresenting to CDP Holders the actual risks they faced, The Maker Foundation neglected its responsibilities to its investors by either fostering or, at the very least, allowing the conditions that led to Black Thursday, all after actively soliciting millions of dollars of investment into its ecosystem,” the complaint states. 

Project Updates

Announcing Gnosis Protocol

Gnosis officially launched their protocol this week which is the result of two years of research and development. Gnosis Protocol is a fully permissionless DEX (decentralized trading protocol) that enables a new mechanism called ring trades to maximize liquidity. Ring trades especially improve liquidity for illiquid or “long tail” tokens such as prediction market outcome tokens, by facilitating trades not normally possible on traditional trading protocols.

You can try it out and trade today on Mesa, the first dapp built on Gnosis Protocol, or directly on smart contract level using this tutorial.

DeFi Market Cap Website Launched

The new website lets you compare various different DeFi assets such as protocol tokens (MKR, ZRX), Compound cTokens, Uniswap pool tokens and much more.
