Deployment architecture

Use this section to design a Lineth (formerly the Linea Stack) deployment: required components, data availability and finalization choices, finality design, and access control. For mechanism internals, see the Protocol architecture.

Architecture

As an Ethereum-equivalent network, Lineth uses a dual-layer architecture separating consensus from execution. This design enables modular deployment, client diversity, and operational flexibility.

• Learn more about the protocol architecture

Deployment models

Lineth allows operators to tweak the deployment model according to their business case, for example, a network built on Lineth can be operated as:

• Private Validium: Offchain data availability, ideal for regulated financial applications
• Public: Fully public network with onchain data availability

See more on the deployment options.

Data availability and finalization

For details on L2/L3 relationships, smart contract requirements, and how data availability differs by deployment model, see data availability and finalization.

Understanding data availability and finalization is key to good deployment decisions.
