FollowingWorld Chain has launched an upgrade of the EIP-7928 main network, ahead of Ethereum
World Chain has confirmed that it will deploy EIP-7928 on its main network on August 17, 2026, becoming the first production-level Layer-2 network to implement streaming block-level access lists (BAL). This upgrade aims to accelerate block verification and significantly increase network throughput without increasing additional costs for independent verifiers.
What is the EIP-7928 upgrade for World Chain?
EIP-7928 is an Ethereum proposal that introduces block-level access lists that record structured information for each account and storage slot touched during block execution. Typically, the validator must re-execute transactions one by one because subsequent transactions may rely on earlier state changes in the same block, creating a serial bottleneck that limits the size of the block.
BAL eliminates this bottleneck by clarifying status changes in advance. Once the verifier knows what each transaction will read and write, there is no need to guess dependencies through sequential execution-transactions can be verified simultaneously on multiple processor cores. World Chain integrates it into existing flash block systems to stream access list data one piece every 200 milliseconds without waiting for the complete block to be built.
How will upgrades improve World Chain?
The core advantage lies in parallel transaction verification. As the flash blocks arrive, verification is no longer completed gradually by a single verifier, but is spread over the available CPU cores. This is designed to support throughput of up to 1 billion gas per second while keeping the hardware requirements of independent validators unchanged. The result is reduced latency and a verification process that can scale as network activity grows.
Main features:
Main network launch time: August 17, 2026
Upgrade content: EIP-7928
Network: World Chain
Key functions: Streaming block-level access list (BAL)
Flash block interval: every 200 milliseconds
Target throughput: 1 billion gases per second
Activation method: Runtime flags
Hardware requirements: No additional verifier hardware required
Comparison of World Chain and Ethereum Project EIP-7928 deployments
Ethereum plans to introduce EIP-7928 to the main network in future Glamestead upgrades, which requires a coordinated network-wide hard fork. World Chain takes a different path, activating the feature through runtime flags that client operators can adopt, without the need to synchronize upgrade events. This difference allowed World Chain to be the first to go online, making it the first production-level streaming block access list implementation before the Ethereum network itself was deployed.
Timeline:
July 27, 2026: EIP-7928 is launched on the World Chain Sepolia test network
August 6, 2026: World Chain announces mainnetwork deployment on August 17
August 17, 2026: EIP-7928 launches on the World Chain main network
Future: Ethereum is expected to adopt EIP-7928 in Glamestead upgrades
What this means for Ethereum expansion
Expanding blockchain often means requiring verifiers to run larger, more expensive hardware. World Chain's approach attempts to avoid this tradeoff by changing the verification process from serial to parallel, which helps keep independent verifiers competitive and maintains decentralization while improving throughput. Faster block verification also shortens the delay between block construction and confirmation, which is important for both daily users and developers building on the network. Once the main network is upgraded and launched, it is worth noting whether actual throughput and verifier engagement can be maintained outside the test environment-and whether Ethereum's Glamstam implementation will adopt a similar streaming approach.
Conclusion
World Chain will become the first production-grade Layer-2 network to launch streaming block access lists, designed to improve throughput without raising the threshold for independent verifiers. With the mainnet deployment scheduled for August 17, this deployment could become an early verification point of how the broader Ethereum ecosystem can respond to the challenges of expansion in the coming years.
