## What it is
Linera is a decentralized Layer-1 blockchain protocol implemented in Rust, designed for highly scalable, low-latency Web3 applications using a microchain architecture. This repository contains the full protocol implementation including cryptography, execution, chain logic, storage, and RPC layers.

## Use cases
- build a scalable web3 application with low-latency transactions
- develop and deploy smart contracts in Rust compiled to WebAssembly
- run a Linera validator or node
- explore a parallel-execution blockchain protocol
- implement cross-chain messaging between microchains

## When to choose
- you need high-throughput, low-latency blockchain infrastructure
- you want to write smart contracts in Rust targeting WASM
- you're building Web3 apps that benefit from per-user microchains

## When to avoid
- you need a mature, widely audited blockchain with a large ecosystem
- you want EVM/Solidity compatibility
- you need a simple token or DeFi stack with existing tooling

## Facets
- artifact type: application
- maturity: active
- function: blockchain, cryptography, wasm, rpc, database, sdk
- domain: blockchain, microservices, web-development
- platform: rust, wasm
- tags: web3, smart-contracts, layer-1, microchains, low-latency, scalability, cryptocurrency, linux, macos, docker
