The Ethereum “Glamsterdam” upgrade is about to go live, the largest protocol change since The Merge
Ethereum’s next batch of feature updates, “Glamsterdam,” is scheduled to be deployed on the mainnet, expected to launch in the second half of 2026. This is the largest-scale protocol change for Ethereum since “The Merge.”
Two core upgrades:
EIP-7732: Embedded Proposer-Builder Separation (ePBS)
Separate the responsibilities of block building and block proposing, directly embedding them into the protocol core. The goal is to eliminate reliance on trust in third-party relays, reduce the space for MEV manipulation, and improve network efficiency.
EIP-7928: Block-level Access Lists (BALs)
Introduce a new data structure that allows validators to declare in advance which accounts and contract data a set of transactions will access. This lays the foundation for parallel transaction processing, enabling the network to handle non-interfering transactions at the same time and significantly increase throughput.
Other improvements:
In terms of developer experience, EIP-7708 makes logs for ETH transfers and burning easier to track, EIP-8024 introduces new opcodes, and EIP-7954 raises the maximum contract size to about 32 KiB. For gas fees, EIP-7778 implements a new gas accounting approach with no refunds, EIP-8037 increases the gas cost for creating states, and EIP-7976 and EIP-7981 respectively increase the costs of calldata and access lists.
Three key goals:
Faster processing (parallelization), greater capacity, and preventing database bloat.
Timeline:
Mainnet launch targeted for the second half of 2026. As of June, the upgrade has entered the final development testnet stage.
Glamsterdam aims to rebuild Ethereum L1’s transaction processing from the ground up, paving the way for the next stage of scaling.
