World Chain has announced the launch of full block access lists, becoming the first production Layer-2 blockchain network to stream EIP-7928 block access lists within every flashblock.
The feature is scheduled to go live on World Chain Mainnet on Aug. 17 and is designed to improve transaction throughput without increasing hardware requirements for validators.
According to the company, as blockchain networks process more transactions, validators typically require greater computing power to verify blocks.
World Chain said its implementation allows validators to verify blocks in parallel while they are still being built, with the goal of increasing throughput to as much as one gigagas per second while keeping validator hardware requirements largely unchanged.
Traditionally, validators must verify every transaction in a block one after another before confirming the block.
According to World Chain, full block access lists record the blockchain state that each transaction reads and writes, allowing independent transactions to be verified in parallel across multiple CPU cores.
World Chain said it extends the EIP-7928 specification by streaming access list data every 200 milliseconds through its flashblock architecture.
This allows validators to begin verifying transactions while a block is still being assembled, rather than waiting for the completed block, reducing validation time and distributing the verification workload throughout the block-building process.
According to the company, the feature will be introduced through a runtime flag instead of a hard fork, unlike Ethereum’s planned implementation of EIP-7928 as part of the proposed Glamsterdam upgrade.
This allows client operators to upgrade before the Aug. 17 mainnet rollout without requiring a coordinated network-wide upgrade.
According to World Chain, internal testing on its test networks showed that validation latency remained largely stable as throughput increased, reaching up to one gigagas per second using standard cloud infrastructure.
The company said the results indicate that blockchain networks can increase transaction throughput without a corresponding increase in computing resources for validators.
World Chain said the rollout marks the first production implementation of streamed EIP-7928 block access lists and contributes to Ethereum’s broader scaling efforts.
According to the company, the implementation is intended to improve network throughput while helping maintain accessibility for independent validators.
