Summary
Ethereum developers have scheduled the Glamsterdam upgrade to activate on the Sepolia testnet on October 6. The upgrade introduces proposer-builder separation, block-level access lists, and new gas pricing mechanisms. The mainnet activation date for Glamsterdam has not yet been set.
Why it matters
According to the Ethereum Foundation, Glamsterdam’s changes aim to reduce reliance on outside middleware by moving proposer-builder separation into the protocol, and adjust gas pricing to better reflect actual costs. The upgrade may require contract modifications due to changes in gas stipend and limits. The source does not elaborate further on market or policy impacts.
Key context
Glamsterdam follows prior Ethereum upgrades and introduces protocol-level improvements. It will be tested on Sepolia and later on Hoodi, another validator-focused testnet, with no mainnet date determined. The following planned upgrade, Hegotá, is targeted for 2027 and is expected to be the last traditional fork before Ethereum shifts toward advanced technologies like recursive STARKs and quantum-safe cryptography, as noted by co-founder Vitalik Buterin.
Key numbers and entities
The upgrade is scheduled for October 6 on Sepolia. Ethereum Foundation is the overseeing organization. Ethereum co-founder Vitalik Buterin commented on future upgrade plans. Testnets mentioned are Sepolia and Hoodi. The next planned upgrade is Hegotá in 2027.
What remains unclear
The exact timeline for Glamsterdam’s rollout on Hoodi testnet and Ethereum mainnet remains unset. Specific impacts on Ethereum users or the broader market are not detailed. Details on how existing contracts will be adapted are not provided.
