# Learn About Sei

> Discover Sei Network's architecture, performance features, and ecosystem, with detailed resources on consensus, tokenomics, governance, and development frameworks.

**Performance-Optimized Ethereum Compatibility**

Sei's EVM implementation addresses traditional performance constraints through three key subsystems that work together to deliver unparalleled speed while maintaining full compatibility with the Ethereum ecosystem.

## Sei Giga: the next-generation architecture

**Designed to be the first Multi-Proposer EVM Layer 1**

Sei Giga will be the next generation of the Sei protocol following the Giga Upgrade. It will arrive as in-place upgrades to the live network. Every validator will propose concurrently, consensus will finalize only the transaction order, and execution will run asynchronously. On an internal devnet this architecture sustained more than 5 gigagas per second (200,000+ TPS) with ordering finality under 250 ms.

<CardGroup cols={3}>
  <Card horizontal title="Autobahn Consensus" icon="bolt">
    Multi-Proposer BFT: per-validator lanes, 1.5 round trips, sub-250 ms ordering finality.
  </Card>

  <Card horizontal title="Async Execution" icon="clock">
    Consensus will fix ordering; execution and state attestation will follow off the critical path.
  </Card>

  <Card horizontal title="Parallel Execution" icon="shuffle">
    Block-STM-style optimistic concurrency across all CPU cores.
