## What it is
Sei Chain is the Go implementation of the Sei Layer 1 blockchain, a delegated proof-of-stake network featuring a parallelized EVM and CosmWasm execution. It includes optimizations like Twin Turbo consensus, optimistic parallelization, and SeiDB for high-throughput, low-latency transaction processing.

## Use cases
- run a Sei blockchain node or validator
- deploy EVM smart contracts on a high-performance L1
- build dApps needing fast finality and parallel transaction execution
- serve EVM JSON-RPC endpoints for Ethereum tooling
- operate a testnet validator on Atlantic-2

## When to choose
- you need EVM compatibility with parallel execution and sub-second finality
- you want to run validator or full-node infrastructure for Sei
- you're building high-throughput DeFi or trading applications

## When to avoid
- you need a simple smart contract deployment without running node infrastructure
- you require IBC support, which was removed in v6.7
- you need a managed blockchain service rather than self-operated nodes

## Facets
- artifact type: application
