The Gasper Proof-of-Stake that Ethereum will soon implement is a complex but very powerful system. It features very strong single-block confirmations, economic finality, very predictable rewards, and support for a very high validator count. Developing a system with these properties is difficult and has taken years of research, failed experiments, and a huge amount of effort. This article discusses Ethereum's choice to develop a complex Proof-of-Stake when a simpler version would have sufficed and considers what would have happened if the network had chosen a different path.

This Twitter thread links to a three-part series on Curve Finance and the Curve wars. The first part is on understanding Curve, a DeFi application that provides a specialized trading market.

Hackers have stolen $600 million worth of ETH from the Ronin network. Ronin is an Ethereum side-chain that is secured by nine validators. Only five validators are required to perform a 50% attack on the network. The hackers accessed a system that operates four of the nodes and then found an exploit to access another node. The ETH was sent to FTX. Ronin is working with government agencies and FTX to recover the funds. Screenshots of the transactions are available in the thread.

This Twitter thread discusses the Curve Wars and provides some tips on how to profit off them. The DeFi world revolves around liquidity and incentives. Protocols incentivize liquidity providers with rewards to attract more liquidity. Curve is a decentralized exchange with low trading fees, low slippage, composability, and token rewards. CRV token holders can earn rewards by locking in their tokens. Stakers are able to vote on which pools rewards are allocated to. This has resulted in protocols looking to control as much of the staked tokens as possible.
