Ethereum Client Prysm Ships 200M Gas Limit Fix Hours Before Glamsterdam Test
By Unchained
AI summary of the source article
Offchain Labs released version 7.2.1 of the Prysm Ethereum consensus client just hours before the Glamsterdam upgrade activates on the Sepolia testnet. The update automatically sets validators' gas limit default to 200 million, replacing the previous 60 million default in version 7.2.0 that required manual configuration. Glamsterdam packages the Gloas consensus and Amsterdam execution changes, featuring enshrined proposer-builder separation (ePBS) and parallel transaction processing via block-level access lists. Meanwhile, fellow consensus client Teku still defaulted to 60 million. Activation dates for Hoodi and the Ethereum mainnet have yet to be decided.
Why it matters
A higher gas limit permits more transactions per block on Ethereum testnets, testing validator machine load ahead of potential mainnet implementations.
Key facts
- Prysm version 7.2.1 defaults validators to a 200 million gas limit upon the Glamsterdam fork on Sepolia.
