💨 What’s happening: Sei Research Initiative explored how the network can implement its Giga upgrade to provide faster finality without changing how many validators need to confirm a block.

💨 Why it matters: Most chains that get faster do so by reducing the number of validators needed to approve a block, spread the same security budget across multiple obligations at once, or confirm transactions before they actually are verified. Each approach makes the chain faster on paper, while lowering the cost of reversing transactions in practice.

Sei Giga is designed to make the blockchain faster in a different way: It separates the steps involved in processing a transaction (receiving data, ordering it, and executing it), and optimizes each one independently. This results in sub-400ms confirmation times — without changing how many validators need to agree on a block, or how much it costs an attacker to corrupt them.

💨 The bigger picture: Two trends across the industry illustrate the trade-offs in improving confirmation times.

The first is looser approval rules. Some chains require fewer validators to reach agreement in order to confirm blocks faster. While this approach works, it also enables bad actors to force an attack, since they need a smaller share of the network to cause damage.

The second is shared collateral. Some networks allow the same staked funds to simultaneously back multiple services, like bridges, oracles, or sequencers. If one of those services fails, the fallout can spread. 

Sei Giga seeks to ensure transactions are confirmed faster, but without loosening security, by separating how transaction data is received, ordered, and executed. Instead of bundling each transaction together, which would mean each step has to wait for the previous one to be resolved, data is spread across three validators who can simultaneously propose transactions in their independent lanes. Ordering is then determined by a designated leader, who collects snapshots of the network to then make a single consensus decision. 

Sei’s research arm claims its tests against the network show that speed and security don't necessarily have to trade off against each other.
