If someone says that the transaction speed of L1 is irrelevant, they might just be creating a vase.

The reason Sei Network is getting attention lies here - it comes into play when your application needs real high-speed response.

How is it done? Sub-second finality is fundamental, meaning transactions can be finally confirmed in less than a second. But that's not enough. Sei employs a parallelized EVM architecture, allowing multiple transactions to be processed simultaneously instead of queuing. Even more impressive, it directly embeds the order book engine into the chain layer, making trade matching extremely efficient.

In other words, this is not just a simple speed accumulation, but a full-chain optimization from consensus to execution to settlement. For high-frequency trading, on-chain DEX, or any application that requires responsiveness, this architectural design is not just a minor upgrade, but a paradigm shift.
