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.

- Learn more about the protocol architecture
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.
