Protocol upgrade decouples consensus from execution to solve scaling bottlenecks

High-performance blockchains often run into the same architectural limit, where the execution sits directly in the path of consensus. In a conventional synchronous model, validators must first execute the transactions inside that block to confirm the resulting state transitions are valid.

The design keeps the network deterministic, but it also turns computation into a shared bottleneck. Whether they involve richer smart contract logic, cross-system coordination, or heavier state updates, the more complex the transactions are, the more the network’s speed depends on how quickly validators can process them.

The slowest computation on that path can end up constraining the pace of the entire system. Many networks have already spent years improving finality, networking efficiency and block propagation.

Execution has become the next architectural constraint. Rather than only optimizing how quickly validators reach agreement, newer designs are starting to ask whether execution needs to remain inside the consensus loop at all.

Shifting to an asynchronous computation pipeline

CTDG Dev Hub participant MultiversX removes that constraint with Supernova, now live on testnet, by decoupling consensus from execution so the network can agree on blocks before processing their transactions.
