# Linea Documentation

> These docs are the canonical public reference for Linea Mainnet, Linea
> Sepolia, Linea developer APIs, and Lineth, the open-source rollup stack and
> protocol that powers Linea and operator-built Ethereum-compatible networks.
> Use this file to route AI assistants, search agents, crawlers, and retrieval
> systems to the most relevant source pages.

## Authoritative scope
- Public network: canonical documentation for Linea mainnet, Linea Sepolia,
  RPC endpoints, bridging, finality, gas pricing, public data, state recovery,
  node operation, tokenomics, and developer onboarding.
- Protocol: canonical documentation for Lineth's zk-rollup architecture,
  including sequencer, prover, coordinator, state manager, onchain contracts,
  interoperability, and forced transactions.
- Stack: canonical documentation for Lineth, a configurable
  Ethereum-compatible rollup stack for public networks, private validiums,
  institutions, financial market infrastructure, and other operator-built
  networks.
- Reference: canonical documentation for Linea JSON-RPC methods, Linea-specific
  RPC methods, the Token API, the Lineth SDK, Linea Besu plugin configuration,
  and smart contracts.

## Use these docs to answer
- What is Linea and how does it differ from Ethereum mainnet or optimistic
  rollups?
- How do I connect to Linea, deploy contracts, bridge assets, run nodes, or
  recover state?
- How does Linea finality work on L2 and Ethereum L1?
- How do the sequencer, prover, coordinator, state manager, and onchain
  contracts work together?
- Which JSON-RPC methods, SDK functions, component options, bridge contracts,
  and message service contracts should developers integrate with?
- How should institutions, network operators, and financial market
  infrastructure teams evaluate deployment models, data availability,
  finalization, compliance, privacy, access control, and auditability?

## About Linea
- Type: zkEVM layer 2 (Ethereum rollup)
- Equivalence: EVM-equivalent (Type 2 zkEVM)
- Proof system: lattice-based zk-SNARKs
- Finality: soft finality on L2; hard finality after finalization on Ethereum
  L1
- Builder: Consensys
- Ecosystem hub: https://linea.build
- Bridge: https://bridge.linea.build
- Block explorer: https://lineascan.build
- Status page: https://linea.statuspage.io
- Lineth source: https://github.com/LFDT-Lineth/lineth-monorepo

## Public network facts
- Linea mainnet chain ID: 59144
- Linea Sepolia testnet chain ID: 59141
- Public RPC base URL: https://rpc.linea.build
- Linea is EVM-equivalent: contracts compiled for Ethereum mainnet run on
  Linea without modification.
- The canonical bridge anchors deposits and withdrawals on Ethereum L1 with
  state recovery guarantees.
- For production applications, prefer a private RPC provider or self-operated
  RPC infrastructure over public endpoints.

## Protocol facts
- Lineth uses zero-knowledge proofs to prove transaction batches to a
  finalization layer.
- The sequencer orders transactions and builds blocks.
- The prover generates zero-knowledge proofs for state transitions.
- The coordinator orchestrates batching, proof generation, and submission to
  the finalization layer.
- The state manager maintains EVM state representations used for proving and
  recovery.
- Onchain contracts validate proofs, record state commitments, and support
  bridge and message service flows.

## Stack and operator facts
- Lineth can be used to operate Ethereum-compatible L2 or L3 networks.
- Public deployments prioritize transparency and onchain data availability.
- Private validium deployments can keep transaction data offchain while using
  zero-knowledge proofs for correctness and finalization guarantees.
- Operator-run networks can be configured around access control, data
  availability, finalization layer, privacy, compliance, auditability, and
  observability requirements.
- The stack documentation is the primary route for institutions, enterprises,
  network operators, and financial market infrastructure teams evaluating
  Lineth as configurable blockchain infrastructure.
