Ethereum co-founder Vitalik Buterin is looking for ways to speed up transactions on the Ethereum network using tools that will potentially reduce layer-1 (L1) confirmations from seconds to milliseconds. 🚀 Buterin proposes abandoning Ethereum's current epoch and slot mechanism in favor of a single slot finality (SSF) system, pointing out key problems with such implementations. He stressed that there is potential to further speed up transactions.
