A daily record of what changed in Ethereum protocol work, research and the ecosystem.

The RESERVOIR opcode became EIP-8455 and opened a Magicians thread that drew 12 posts in a day. The EIP-8450 post-quantum validator key registry now relies only on the BLS signing key for authorization and no longer changes the execution layer. On Magicians, an STVA transaction verification ERC was proposed against Bybit-style multisig UI attacks, and on ethresear an "L1.5" pattern uses native AA and proof aggregation to separate compute from state.
The EF App Enablement team asked app teams that rarely join ACD calls for their input, and a Magicians post summarized interviews with staking and oracle teams about EIPs and the roadmap. ethbeat reviewed 16 privacy protocols for what they actually hide, from whom, and what stays visible. EIP-7906 clarified where storage-kept nonce changes appear, and ChainSecurity invited projects to walk through their call paths at Devcon.
On the day Hoodi was originally due to fork, the discussion moved to impact assessment: nero_eth said people spent the weekend trying to understand how EIP-8037 affects contracts, and Barnabé said his team let agents loose on gas repricings and mechanism changes. EIP-8053 now keeps gas units at the contract boundary and was merged, and CALLSTATUS opened a Magicians thread as EIP-8456. The EF stressed that privacy and security cannot be pursued separately. Falcon-512 verification on Starknet got 50.2% cheaper in a week.
The weekend kept circling EIP-8037's failure-handling problem. A new EIP, CALLSTATUS, proposes a 2-gas instruction that tells a contract directly whether its last call reverted normally or ran out of gas through an exceptional halt somewhere below, with no more inference from `GAS` arithmetic. The EIP-8141 PR charging the legacy share was merged. On ethresear, a team described an OP Stack rollup whose accounts are keccak hash chains, with no signatures inside the L2.
Two days after the ChainSecurity report, a fix took shape. A PR from LukaszRozmej credits state gas refills and rollbacks only to the reservoir, so `gas_left` never increases within a frame, and adds a legacy share so a new storage slot still costs its Osaka price in execution gas; the same mechanism goes into EIP-8141. Another PR proposes a RESERVOIR opcode so contracts can see the reservoir balance. EIP-8425 quantum freeze and account recovery was merged as a draft.
The postponement reached the specs and announcements: the EF and Alex Stokes posted notices for operators, EIP-7773 cleared the Hoodi activation time, and a new EIP-8037 PR writes "spent gas can come back before settlement" into its security considerations. lightclient said publicly that he does not like EIP-8037/8038, since they only let the gas limit rise without solving ever-growing state. Frame transactions now bound cost with a single `max_fee`, and `GASPRICE` returns a lower bound.
ACDE #248 decided to postpone the Glamsterdam activation on Hoodi, planned for October 26, to study EIP-8037's interaction with mainnet contracts; no new date was set. The trigger was ChainSecurity's analysis: the state gas reservoir, immediate refills and repricing can break contract logic that infers an out-of-gas failure from the gas left afterwards, with 13 real-world cases found. The same day, EIP-8453 decoupled consensus published its first draft, and EIP-8141 fixed a billing hole that let relayers pad signatures.
