Sei's latest Giga upgrade pushes finality below 250ms, and also incorporates a privacy layer and anti-MEV, much to the delight of performance enthusiasts.

Wu learned that Sei Labs has released the Giga Whitepaper V2, adding new privacy and fairness designs, reducing the finality target of Giga's Autobahn consensus protocol from 400 milliseconds to under 250 milliseconds, while maintaining a throughput of over 200k transactions / 5 Gigagas per second. The new whitepaper introduces the Sedna private transaction layer and a deterministic transaction ordering mechanism to provide pre-execution privacy, MEV resistance, and censorship resistance. Sei Labs stated that the Giga upgrade is progressing, and subsequent development includes a complete transaction fee mechanism, Autobahn consensus upgrade, and new tokenomics for the SEI token.
