ETH IS ETHEREUM'S MOST IMPORTANT APPLICATION

Summary from the TLDR Crypto newsletter

Gnosis is live with Ethereum's Fast Confirmation Rule (FCR), cutting L1-to-Gnosis deposit times from ~14 minutes to 12-24 seconds, with most consensus clients now shipping FCR behind an opt-in flag. AI agents completed formal verification of the FCR in Lean in 4-5 days, a task that used to take months, and the process caught a subtle fork-choice bug in the spec itself. A Cambridge workshop of 100+ researchers from 70 organizations advanced post-quantum cryptography and fast finality work, with Barnabé presenting a path to finality in tens of seconds in the I* fork after Hegotá, down from the current ~15 minutes. Quick Slots (EIP-8198) joined heze-devnet-2 alongside FOCIL, and Glamsterdam arrives on the Hoodi testnet on October 26.
