Glamsterdam will bring proposer-builder separation, block-level access lists and new gas pricing, while its mainnet date remains unset. Ethereum developers have scheduled the network’s next major upgrade, Glamsterdam, to activate on the Sepolia testnet on Oct. 6. Sepolia node operators must update both their execution-layer and consensus-layer clients before the activation, the Ethereum Foundation said Monday. One of Glamsterdam’s changes is enshrined proposer-builder separation. It will move the handoff between specialized block builders and validators into Ethereum’s protocol, reducing reliance on outside middleware. Read more

The rollout marks the second phase of Ethereum’s three-step roadmap, testing higher gas limits and the new PeerDAS data-sampling system. Ethereum’s Fusaka upgrade has been activated on the Sepolia testnet, marking the next major step in the network’s ongoing push to improve scalability and performance. The upgrade marks the second phase of a three-step rollout under Ethereum’s Fusaka roadmap, following the Holesky testnet activation on Oct. 1. The Sepolia deployment focuses on stress testing the network’s new data-availability system and higher block gas limit before developers push the code to the final Hoodi testnet later this month. Fusaka’s rollout is introducing a suite of performance and consensus improvements. The full upgrade aims to increase Ethereum’s block gas limit to 60 million, allowing blocks to process more transactions and complex smart-contract activity while testing whether nodes can maintain stability at higher capacity.
