Ethereum Sellers Go Quiet as the Glamsterdam Countdown Begins

Glamsterdam bundles Ethereum's Amsterdam execution-layer and Gloas consensus-layer changes, promising a gas limit raised to 200 million along with enshrined proposer-builder separation and block-level access lists. The higher gas limit had already run cleanly on the Sepolia testnet, which is why Hoodi was picked as the next public rehearsal before a mainnet date. EIP-8037, the gas-accounting rule now under review, sits at the center of why that rehearsal stalled four days before launch.

Node operators were told to keep running client software without the scheduled fork rather than prepare for an Oct. 26 cutover, leaving validator teams without a near-term deadline to plan around. ChainSecurity flagged 13 real-world contracts that could behave differently under the new gas rules and is now coordinating private disclosure with the affected projects before any public detail follows. The 200 million gas limit increase that was bundled with the fork is frozen too, so the capacity gain developers and rollups were expecting is on hold indefinitely.

The concern ChainSecurity raised is not cosmetic: on deployed contracts nobody can alter, some failure paths that currently run out of gas and revert could start succeeding instead under the new accounting. That is the core bind in upgrading a chain whose main selling point is that code, once live, cannot be changed by anyone, including its own developers. Scaling Ethereum keeps requiring protocol-level changes that brush against contracts frozen in place since deployment, and this episode shows how thin that margin can be.

Ethereum.org has confirmed only that the postponement stands and that no replacement activation date has been set, so the next concrete marker is whatever new Hoodi schedule developers publish once the EIP-8037 review and ChainSecurity's disclosure process conclude. Until a fresh epoch and UTC timestamp replace the cancelled Oct. 26, 17:42:48 slot, there is no mainnet date to anchor expectations, and any resumption will signal whether the gas-accounting fix satisfies the contracts flagged as at risk.
