Features

The Linea stack provides features and capabilities that enable various deployment models and use cases. This section highlights just some of the features available in the Linea stack.

The stack is designed to support enterprises with an extensible and configurable ledger solution to suit different operational, regulatory, and performance requirements.

tip

Reach out to support.linea.build for assistance in designing your enterprise deployment. From transaction ordering, to data availability, to block times, Linea's rich extensible architecture supports concise ledger configurations to match your enterprise needs.

Deployment model features​

Using the Linea stack, you can deploy:

  • Public networks, such as Linea Mainnet
  • Private validium networks, with offchain data availability and controlled access
  • Custom L2 or L3 networks

Private validium​

A private validium configuration provides:

  • Offchain data availability: transaction data stored privately
  • RBAC: Role-Based Access Control (RBAC) for RPC and API endpoints
  • Privacy: transaction details not visible on finalization layer
  • Compliance: Selective data disclosure
  • API portal: controlled access to network functionality

See more on private validiums.

Public​

Public deployments provide:

  • Onchain data availability: the Linea Mainnet posts all data via EIP-4844 blobs to Ethereum
  • Full transparency: All transactions visible on finalization layer
  • Open access: No access controls required

Core features​

Zero-knowledge proofs​

The Linea stack uses zero-knowledge proofs to:

  • Verify state transitions without revealing transaction details
  • Provide cryptographic guarantees of correctness
  • Enable efficient finalization on the finalization layer

EVM equivalence​

Full EVM compatibility enables:

  • Deploy existing Ethereum smart contracts without modification
  • Use standard Ethereum tooling and libraries
  • Maintain compatibility with Ethereum ecosystem

Dual-layer architecture​

Separation of consensus and execution provides:

  • Client diversity and network resilience
  • Modular deployment and scaling
  • Operational flexibility

Quorum-Based Byzantine Fault Tolerance consensus​

Quorum-Based Byzantine Fault Tolerance (QBFT) consensus enables:

  • Fault tolerance (3f+1 nodes)
  • Fast finality
  • Decentralized block production (with sufficient validators)
