How it works

This section introduces how the Linea stack works from an operator's perspective. It surfaces the architecture, deployment models, and component boundaries you need to understand to run a network effectively.

Architecture

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

Deployment models

The Linea stack allows operators to tweak the deployment model according to their business case, for example, Linea 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.
