GWYNETH — A BASED ROLLUP SYNCHRONOUSLY COMPOSABLE WITH ETHEREUM

Summary from the TLDR Crypto newsletter

Gwyneth is a new based rollup, meaning transactions are sequenced by L1 validators with blocks constructed by L1 builders. It is a synchronously composable “booster rollup,” allowing for seamless access to the L1's state with no fragmentation. Gwyneth was built using Taiko's prover technology and will eventually utilize zkVMs like SP1 and Risc0 for transaction execution.
