Sei has emerged as the first Layer-1 blockchain specifically optimized for decentralized trading, DEXs, and DeFi applications. Launched in August 2023, it achieves unparalleled transaction speeds with zero downtime to date, solidifying its position as a leader in blockchain performance.
Key Performance Metrics
- Block Finalization: 390 milliseconds (fastest in the industry)
- Transactions Per Second (TPS): Consistently over 45 TPS
- Architecture: Integrated blockchain handling execution, settlement, consensus, and data availability in a single network
- Interoperability: Compatible with Cosmos’ IBC protocol, built using Cosmos SDK and Tendermint Core

Twin Turbo Consensus: The Engine Behind Sei’s Speed
Sei challenges the modular vs. monolithic blockchain debate by achieving unmatched speed through its Twin Turbo consensus. This innovation focuses on reducing time to finality—the duration for validators to reach consensus globally.
Core Optimizations:
Optimistic Block Processing:
- Validators process transactions immediately upon receiving a block proposal, caching candidate states.
Intelligent Block Propagation:
- Proposers send compact block proposals (transaction identifiers + block reference) before full blocks.
Result: Sei is ~2,000x faster than Ethereum, with sub-400ms block times and single-slot finality.
Sei V2: Parallelized EVM and Storage Upgrades
In November 2023, Sei V2 introduced parallelized EVM (PEVM), making it the first production-ready blockchain with this capability.
Key Features:
- Backward Compatibility: Ethereum smart contracts deploy seamlessly on Sei without code changes.
- Optimistic Parallelization: Transactions run concurrently, with results reordered linearly post-execution.
- SeiDB: A redesigned storage layer separating State Commitment (SC) and State Store (SS) to enhance performance and reduce node operator hardware demands.
