Glamsterdam is set to introduce proposer-builder separation, block-level access lists, and revised gas pricing, though an official mainnet launch date has not yet been determined.
Ethereum contributors have set the network’s upcoming major network upgrade, known as Glamsterdam, to go live on the Sepolia testnet on October 6.
Operators of Sepolia nodes are required to upgrade both their consensus-layer and execution-layer clients ahead of the launch, as stated by the Ethereum Foundation on Monday.
Among the key modifications included in Glamsterdam is enshrined proposer-builder separation. This feature integrates the transition between specialized block creators and validators directly into the protocol of Ethereum, thereby minimizing dependence on external middleware.
Furthermore, Glamsterdam will implement block-level access lists, which document the storage locations and accounts accessed throughout every individual block.
The network upgrade will additionally modify gas pricing mechanisms to more accurately match the expenses associated with generating and retrieving data on Ethereum. The foundation noted that smart contracts depending on hardcoded gas limits or fixed gas stipends could need modifications.
As of now, builders have not established launch timelines for the validator-centric Hoodi testnet or the primary mainnet.
Engineering teams are aiming for 2027 to deploy Hegotá, which is the network upgrade scheduled to come after Glamsterdam.
Ethereum co-founder Vitalik Buterin mentioned on Sunday that Hegotá might serve as the blockchain’s final standard fork before development transitions toward recursive STARKs, quantum-resistant cryptography, streamlined consensus, and automated formal verification.
