ARBITRUM'S TIMEBOOST AUCTION

Summary from the TLDR Crypto newsletter

The Arbitrum DAO recently approved a new sequencing policy called Timeboost, which replaces the first-come-first-serve approach with an auction. Every minute, a winner gets a 200ms advantage for including transactions in blocks, allowing them to capture MEV. Potential risks exist, like incentivizing transaction spamming and MEV going to searchers instead of apps, yet the proposal passed with a heavy majority.
