World Chain to launch streamed EIP-7928 block access lists

• World Chain launches streamed EIP-7928 on mainnet Aug. 17.
• New feature enables parallel block verification for validators.
• Upgrade targets higher throughput without more hardware.

World Chain said it will become the first production layer-2 blockchain to deploy streamed EIP-7928 block access lists, introducing the feature on its mainnet from Aug. 17 in a move aimed at improving 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.

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.

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

Parallel verification targets higher throughput

On most blockchain networks, validators verify blocks by re-executing every 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, enabling 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 begin verifying transactions immediately as the block is built.

World Chain said this approach reduces validation latency while distributing 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.

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

The company said 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.

Focus on scalability and decentralization

World Chain said the rollout is intended to demonstrate a practical approach to improving 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 forms 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.
