Protocol upgrade decouples consensus from execution to solve scaling bottlenecks
CTDG Dev Hub participant’s protocol upgrade decouples consensus from execution, allowing network nodes to reach agreement on blocks before transaction execution completes.
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.
