Glamsterdam enters the final stage, PBS goes live on the blockchain + state cost reconstruction, and the real show begins in the second half of 2026.

CryptoWorld News reports that Ethereum core developers have advanced the Glamsterdam upgrade to the final development stage. A private development network is testing all planned Ethereum Improvement Proposals (EIPs). The upgrade is expected to be launched in the second half of 2026, although the final timing depends on testnet results and client readiness. The main proposals of Glamsterdam include proposer-builder separation (EIP-7732) and block-level access lists (EIP-7928), aiming to improve transparency in block construction and reduce reliance on trust in off-chain relays. Developers said the upgrade will change the costs of operating on Ethereum—likely making higher-level computation cheaper, while state will become more expensive.
