The architectural innovation of Sei Network lies in how to build upon the mature BFT consensus framework. Instead of developing an entirely new consensus mechanism, it starts from the network and execution layers—by optimizing block propagation strategies and introducing an optimistic block processing mechanism, directly compressing the transaction confirmation path.

The real cleverness here is: overlapping execution and voting times. Traditional public chains are linear—completing all transaction executions first, then proceeding with voting consensus. Sei breaks this sequence, allowing the two processes to run in parallel. As a result, confirmation latency is naturally significantly reduced, and throughput is also improved.

What may seem like a simple change is actually a deep optimization of the blockchain's sequential execution bottleneck.
