Ethereum Research Daily

shemnon submitted two post-quantum-related EIPs: EIP-7819 allows trailing data after the delegation designator, with a worked example storing ML-DSA public keys there and accepting them with EIP-8141 code, and the new EIP-8355 provides verification precompiles for FIPS 204 ML-DSA at three security levels. donnoh submitted EIP-8357, an EVM verification key registry, and rakita submitted EIP-8358, net gas metering for account changes. EIP-8347 offline state migration to the PBT merged as a Draft. Ethereal news #33 was published.

A post-quantum account path

New EIP: Precompiles for ML-DSA Verification

(shemnon), submitted as EIP-8355, a "just the FIPS" set of precompiles for all parameter sets. Forum, 07:55: three precompiles verify NIST security levels II, III and V (ML-DSA-44, 65 and 87); it overlaps with EIP-8051, the author lists four specific disagreements, and he would rather fold it into 8051 if those are resolved. EIP-8081: propose EIP-8355 for inclusion, submitted.

Gas and native rollups

New EIP: Net Gas Metering for Account Changes

(rakita), submitted as EIP-8358: a value-bearing call pays for each account whose balance changes for the first time in a transaction, later changes to that account cost less, and restoring the original balance earns a refund if the nonce is unchanged. With EIP-8038's `ACCOUNT_WRITE = 9000`, a call pays a 4000 base plus 2500 per clean account changed; the 2300 gas stipend becomes a floor on callee gas. An applied EIP-7702 authorization changes the authority's nonce, so later calls treat that account as changed.
