World Chain becomes first L2 to stream EIP-7928 block access lists in flashblocks
🌍 World Chain goes first
World Chain is launching a technical first for Layer 2 networks.
The network will stream EIP-7928 block access lists inside every flashblock - a feature currently live on Sepolia testnet and scheduled for mainnet deployment on August 17.
This makes World Chain the first production L2 to implement this streaming capability.
What this means:
- Block access lists help optimize transaction execution
- Streaming them in real-time within flashblocks could improve network efficiency
- Part of the broader OP Stack ecosystem's technical evolution
The deployment follows the Superchain's recent Isthmus hardfork, which brought Pectra upgrades to multiple OP Stack chains including Base, OP Mainnet, and Unichain.
OP Stack ecosystem weekly recap: @world_chain_ will be the first production L2 streaming EIP-7928 block access lists inside every flashblock. Live on Sepolia now, mainnet Aug 17.
Full block access lists are coming to World Chain Mainnet on August 17. This deep dive covers the protocol design, execution model, benchmarks, and why streamed access lists matter for scaling. x.com/i/article/2084…
