World Chain said it will become the first production layer-2 blockchain to deploy streamed EIP-7928 block access lists, with the feature scheduled to go live on its mainnet on Aug. 17. The company said the rollout is intended to improve transaction throughput without increasing validator hardware requirements.

The network said it will stream full block access lists inside every flashblock, allowing validators to begin verifying transactions while blocks are still being assembled. World Chain said the implementation is designed to address one of the blockchain industry’s key scaling challenges: increasing transaction capacity without compromising decentralization by requiring validators to run more powerful hardware.

According to the company, the rollout represents the first production implementation of streamed EIP-7928 block access lists and is part of Ethereum’s broader scaling roadmap.

Parallel verification targets higher throughput

On most blockchain networks, validators verify blocks by re-executing each transaction sequentially before confirming a block’s validity.

World Chain said full block access lists change that process by recording the blockchain state that each transaction reads and writes, allowing independent transactions to be verified simultaneously across multiple CPU cores.

The company said its implementation extends the EIP-7928 specification by streaming access list data every 200 milliseconds through its flashblock architecture. Instead of waiting for an entire block to be completed, validators can start verifying transactions immediately as the block is being built.

World Chain said the approach reduces validation latency while spreading verification work throughout the block-building process. The network said the technology allows it to target throughput of up to one gigagas per second while keeping validator hardware requirements effectively unchanged.

Deployment avoids hard fork requirement

Unlike Ethereum’s planned implementation of EIP-7928, which is expected to arrive as part of the future Glamsterdam upgrade, World Chain said it is deploying the feature through a runtime flag rather than a hard fork.

The company said this approach allows client operators to upgrade software ahead of the Aug. 17 mainnet rollout without requiring a coordinated network-wide upgrade.

World Chain said internal benchmarking on its 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 needed for independent chain verification.

Focus on scalability and decentralization

World Chain said the rollout is intended to demonstrate a practical way to improve blockchain scalability while preserving accessibility for independent validators, which it described as an important requirement for maintaining decentralized networks.

The layer-2 network is built using the OP Stack, secured by Ethereum, and is part of the Superchain ecosystem. It is integrated with the World protocol and is designed to support applications including stablecoin payments, international remittances, commerce, and other real-world use cases.

The network also incorporates World ID’s proof-of-human technology and can be accessed through compatible wallets, including World App.
