Sei Overview
Sei is a Layer 1 blockchain optimized for trading, leveraging Cosmos SDK interoperability. It outperforms competitors by:
- Specialized Infrastructure: Tailored for DEXes, NFT marketplaces, and gaming.
- Native Features: Built-in order-matching engine, Twin-Turbo consensus, and anti-MEV protections.
Twin-Turbo Consensus
Sei enhances Tendermint’s PoS mechanism with:
- Intelligent Block Propagation: Validators reconstruct blocks from transaction hashes, reducing bandwidth.
- Optimistic Block Processing: Concurrent consensus steps cut block times to <400 ms.
- Validator Incentives: Top 39 validators earn fees and staking rewards, with SEI token delegation options.
Parallel Execution
Sei processes transactions in parallel via:
- Directed Acyclic Graph (DAG): Manages transaction order without conflicts.
- Order-Matching Engine: Executes independent orders simultaneously, boosting throughput.
Order Matching Engine
Sei’s chain-level engine supports:
- Central Limit Order Books (CLOBs): Mimics traditional exchange functionality.
- AMM Integration: Compatible with DEX liquidity pools.
Key Innovations:
- Transaction Bundling: Reduces gas costs for multi-market trades.
- Frequent Batch Auctions: Mitigates MEV by executing orders at uniform prices.
Sei V2 Upgrade
Launching H1 2024, Sei V2 introduces:
- Parallelized EVM: Backwards-compatible Ethereum smart contracts.
- Optimistic Parallelization: Auto-detects conflicts for efficient execution.
- SeiDB: Cuts state storage by 60% and improves sync times by 12x.
- Interoperability: EVM and CosmWasm smart contracts interact seamlessly.
