World Chain plans on becoming the first production Layer 2 blockchain to stream full EIP-7928 Block Access Lists inside every flashblock, with the feature rolling out on mainnet on Aug. 17, according to an announcement on Wednesday.
The upgrade enables validators to verify blocks in parallel while they are still being built, targeting throughput of up to one gigagas per second without requiring more powerful hardware.
(A gigagas is a performance metric representing the processing of one billion gas units.) “Traditionally, validators must re-execute every transaction in a block sequentially before confirming its validity,” the statement reads. “Full block access lists instead provide a record of the blockchain state each transaction reads and writes, allowing independent transactions to be verified simultaneously across multiple CPU cores rather than one at a time.” EIP-7928 is an Ethereum Improvement Proposal to add Block-Level Access Lists (aka BALs ) that serve as an enforced, block-level record of all accounts and storage slots accessed during a block’s execution, along with post-execution state differences.
In the end, this will lead to faster block validation.
Proposed in March 2025, BALs will be included as a headliner update for Ethereum’s Glamsterdam hardfork, planned for the second half of the year.
