What is Sei (SEI)?

Sei is a high-performance, general-purpose Layer-1 blockchain designed for digital asset trading and the demands of global finance. Described as the first parallelized Ethereum Virtual Machine (EVM), Sei removes traditional network bottlenecks by pairing parallel execution with full Ethereum compatibility, allowing developers to deploy existing EVM apps and smart contracts seamlessly with low fees and rapid execution.

Sei distinguishes itself by combining the speed advantages of networks like Solana with the established tooling and developer mindshare of Ethereum. Key differentiators outlined in the Sei whitepaper include:

  • First Parallelized EVM: Uses optimistic parallelization across EVM and CosmWasm executions to run transactions concurrently without requiring extra work from developers.
  • Fastest Time to Finality: Its consensus architecture delivers consistent 400ms block times and sub-400ms settlement, providing the fastest finality in the blockchain space.
  • Zero-Friction Migration: Ethereum developers can port applications and infrastructure directly without modifying their code.
  • SeiDB Storage: Features a specialized storage layer optimized for intensive data read and write demands.

According to the Sei whitepaper, Sei promises a low-fee, developer-focused Layer-1 blockchain that delivers 100x performance improvements and transaction throughput orders of magnitude higher than Ethereum while maintaining full EVM compatibility. It also guarantees native interoperability between EVM and CosmWasm execution environments—such as direct access to multi-sig accounts—along with sub-second, 400ms finality powered by its Twin Turbo Consensus.

Sei operates on a Delegated Proof of Stake (PoS) architecture powered by its Twin Turbo Consensus, which achieves sub-400ms finality. For its upcoming Sei Giga upgrade, the network utilizes the Autobahn consensus mechanism, a multi-proposer engine designed to achieve low latency and a 50x throughput improvement over Tendermint while preserving Byzantine Fault Tolerance.

Sei can be bought on the SwissBorg app with just a few clicks. Download the app for Android or iOS and exchange cryptos instantly at the best price.

Sei aims to solve performance and scalability bottlenecks that hinder modern digital asset markets, decentralized finance (DeFi), and high-frequency trading. Traditional blockchains suffer from slow execution, high fees, and delayed finality. Sei addresses these issues by offering parallelized EVM execution, sub-400ms finality, and dedicated infrastructure (such as onchain order books and SeiDB) to handle institutional-grade trading, global payments, tokenized assets, and AI-driven economies without network congestion.

Sei is engineered for extreme scalability and speed. It delivers sub-400ms finality and consistent 400ms block times via its Twin Turbo Consensus and optimistic parallel execution. With the Sei Giga upgrade and the Autobahn consensus engine, the platform is designed to reach execution speeds of up to 200,000 transactions per second (200K TPS), scaling EVM throughput by 50x to comfortably handle massive trading volumes, consumer AI applications, and payment networks simultaneously.

Sei's long-term vision is to establish itself as the onchain standard and core infrastructure for global finance and modern digital economies. Built to serve demanding asset markets, institutions, and builders, Sei aims to push blockchain scalability to web2 performance levels. Through technological developments like Sei Giga, it plans to power high-throughput trading, real-time stablecoin payroll, tokenized real-world assets, and consumer AI platforms simultaneously without bottlenecks.
