World Chain Beats Ethereum to EIP-7928 With First Live Mainnet Deployment

World Chain is putting a technology planned for Ethereum’s future Glamsterdam upgrade into production today, offering an early look at how Ethereum could scale verification.

World Chain has become the first production layer-2 to deploy streamed EIP-7928 block access lists, bringing a key piece of Ethereum’s future scaling roadmap into a live mainnet environment ahead of its planned adoption on Ethereum.

The rollout introduces full block access lists inside every World Chain flashblock, allowing validators to begin verifying transactions in parallel while a block is still being constructed.

That represents a significant shift from the traditional model in which transactions are largely re-executed sequentially during verification. By identifying which parts of blockchain state individual transactions access, EIP-7928 can make it possible for independent transactions to be processed simultaneously.

World Chain has taken the concept a step further by streaming that information incrementally every 200 milliseconds through its flashblock architecture. Instead of waiting for an entire block and its access list to arrive, validators can start working almost immediately.

The significance extends beyond World Chain itself.

EIP-7928 is planned for Ethereum’s future Glamsterdam upgrade, making World Chain’s deployment an early production test of technology expected to play a role in Ethereum’s broader scaling strategy.

World Chain said internal testnet benchmarks showed validation latency remaining effectively stable as throughput increased, with tests reaching as high as one gigagas per second on standard cloud infrastructure.

If those characteristics continue to hold at scale, streamed block access lists could provide blockchain networks with a path to substantially greater throughput without requiring an equivalent increase in validator computing power.

World Chain also deployed the feature using a runtime flag rather than a hard fork, meaning client operators can adopt the upgrade without requiring a coordinated network-wide fork.

For Ethereum’s scaling ecosystem, the launch provides something particularly valuable: real-world data.

Rather than waiting for EIP-7928 to reach Ethereum mainnet, developers can now observe how streamed access lists behave under production conditions on an Ethereum-secured L2 built with the OP Stack.

For World Chain, meanwhile, the deployment positions the network at the front edge of Ethereum execution research as it builds infrastructure intended to support payments, stablecoin finance, international remittances and other high-volume applications.

With EIP-7928 now running in production, World Chain is effectively giving part of Ethereum’s future execution architecture an early mainnet debut.
