World Chain says its latest mainnet upgrade can dramatically increase blockchain throughput without demanding proportionally more powerful validator hardware.
World Chain has rolled out a new verification architecture aimed at one of blockchain scaling’s toughest trade-offs: how to process substantially more activity without making the network increasingly expensive to independently verify.
The Ethereum layer-2 has deployed streamed EIP-7928 block access lists across its mainnet, enabling validators to verify independent transactions in parallel and begin that work before a block has even finished being assembled.
The result could offer a path toward higher-performance blockchains without turning verification into a job reserved for operators with increasingly specialized infrastructure.
World Chain said internal testnet benchmarking reached throughput of up to one gigagas per second on standard cloud infrastructure while validation latency remained effectively stable as throughput increased.
That distinction matters because blockchain performance is not simply a question of how quickly a network can produce blocks. A network also needs independent operators to be able to verify what happened.
If increasing throughput causes verification requirements to rise at the same rate, scaling can ultimately put pressure on decentralization by increasing the hardware needed to participate.
World Chain’s approach is designed to break that relationship.
Using EIP-7928 block access lists, validators can determine which blockchain state each transaction interacts with and identify transactions that can safely be verified simultaneously rather than processing everything sequentially.
World Chain then streams that information every 200 milliseconds through its flashblock architecture. Validators therefore do not need to wait for the completed block before starting verification.
The mainnet deployment is the first production implementation to stream EIP-7928 access lists inside every flashblock, according to World Chain.
It could also provide an important preview for Ethereum. EIP-7928 is planned as part of Ethereum’s future Glamsterdam upgrade, meaning lessons from World Chain’s live implementation could help inform the technology’s broader adoption.
World Chain introduced the capability through a runtime flag rather than a hard fork, reducing the coordination required for client operators to upgrade.
The development is particularly relevant as blockchain networks pursue mainstream use cases where significantly greater transaction capacity may be required. World Chain is being developed around applications including stablecoin finance, international remittances and commerce, where higher throughput can become increasingly important as usage grows.
The bigger achievement, however, may not simply be making the chain faster.
By demonstrating parallel verification on a production network while keeping hardware requirements effectively unchanged, World Chain is testing a model in which blockchain capacity can grow without making independent verification progressively harder.
That could make the rollout as much a decentralization milestone as a performance one.
