## What it is
CITA is a high-performance, open-source blockchain kernel written in Rust, designed for enterprise consortium chains. It uses a microservice architecture with pluggable components, supporting native and EVM smart contracts and Ethereum development tooling.

## Use cases
- build a permissioned consortium blockchain for an enterprise
- run a high-throughput blockchain node cluster with horizontal scaling
- deploy smart contracts using Solidity or Rust on a private chain
- customize consensus algorithms or storage backends for a blockchain
- integrate Ethereum tools like Truffle and Remix with a private chain
- take snapshots to back up and quickly resync blockchain data

## When to choose
- you need a permissioned, enterprise-grade consortium blockchain
- you want pluggable consensus and microservice-based node architecture
- you need EVM compatibility with Ethereum developer tooling
- high transaction throughput on multi-core, multi-server setups matters

## When to avoid
- you need a public blockchain with a large existing ecosystem
- you want an actively developed project with recent releases
- you prefer a simple single-binary node over a microservice deployment
- your team is not comfortable operating Rust-based infrastructure

## Facets
- artifact type: framework
- maturity: maintenance
