@worldnetwork says it will become the first production Layer 2 to stream EIP-7928 block access lists, going live on mainnet on August 17. The network will stream full block access lists inside every flashblock, allowing validators to begin verifying transactions while blocks are still being assembled. That inverts the usual approach, where nodes must replay everything sequentially after a block is complete.
Block-Level Access Lists (BALs) function like a map for the network, detailing which parts of the database will be accessed before the work begins. The execution layer stores the full Block Access List, including every account change that the transactions will touch, along with the final results of those changes.Because they give instant visibility into which transactions do not overlap, BALs allow nodes to perform parallel disk reads, fetching information for many transactions simultaneously.
Unlike Ethereum's planned implementation of EIP-7928, which is expected to arrive as part of the Glamsterdam upgrade, World Chain is deploying the feature through a runtime flag rather than a hard fork. This approach allows client operators to upgrade software ahead of the August 17 mainnet rollout without requiring a coordinated network-wide upgrade.
Internal benchmarking on World Chain test networks showed validation latency remained effectively stable even as throughput increased substantially, reaching up to one gigagas per second using standard cloud infrastructure. According to the results, higher transaction throughput can be achieved without a corresponding increase in the computing resources required for independent chain verification.
The implementation is designed to address one of the blockchain industry's key scaling challenges: boosting transaction capacity without compromising decentralization by forcing validators to use increasingly powerful hardware.
For @ethereum, EIP-7928 is central to its own roadmap. Glamsterdam is Ethereum's next major network upgrade after Fusaka, combining the Gloas consensus layer fork and the Amsterdam execution layer fork. It is headlined by two changes: enshrined proposer-builder separation (EIP-7732), which moves block building into the protocol, and Block-Level Access Lists (EIP-7928), which enable parallel transaction execution.Glamsterdam is Ethereum's next hard fork after Fusaka, targeting activation at the end of August 2026.
World Chain's early rollout gives the broader Ethereum ecosystem a live production data point on EIP-7928 ahead of that hard fork, potentially informing how the feature performs under real network conditions.
