Overview
The Linea stack
The Linea stack is the collection of protocol components, onchain contracts, and operational capabilities used to deploy and operate Linea networks. The Linea stack provides a shared, extensible foundation that enables operators to run their own Layer 2 or Layer 3 networks while inheriting Linea’s zero-knowledge security guarantees, Ethereum compatibility, and composability with the broader Ethereum DeFi ecosystem.
Why the Linea stack exists
The Linea stack supports operators who need more control than a layer 1 network can offer, without sacrificing interoperability, security guarantees, or alignment with the EVM protocols. Whether you are deploying a private network for regulated environments, you favor selective data availability, or are operating a fully public network, the Linea stack gives you the components and operational model to do so.
As blockchain adoption grows, many organizations encounter a common set of constraints:
- Layer 1 transactions can be expensive and slow
- Public networks do not offer sufficient privacy or control
- Bespoke infrastructure is costly to build and difficult to maintain
- Regulatory, governance, and operational requirements are hard to enforce on open systems
- Interoperability between private systems and public blockchains remains fragmented.
The Linea stack lets you run an EVM-equivalent network tailored to enterprise requirements, using open source technology, while remaining anchored to the same protocol foundations as Linea Mainnet.
What the Linea stack provides
At a high level, the Linea stack provides:
-
Low-cost transactions: 10× cheaper than Ethereum L1 costs.
-
Fast transactions: Linea's 2s block times supports near-instant soft finality.
-
Trustless Ethereum interoperability: Access Ethereum's deep liquidity via Linea's trustless rollup architecture.
-
An EVM-compatible execution environment: Run an EVM-equivalent network.
-
Composability: Leverage a trustless bridge for with Ethereum to interact with digital assets and compose with the largest open, modular DeFi ecosystem.
-
Flexible deployment models: Deploy rollup networks with customizations to suit your privacy, compliance, and availability requirements.
-
Privacy and data availability controls: Keep transaction data private as required, while still benefiting from trust-minimized finalization.
-
Operational clarity and control: Clearly defined components, responsibilities, and failure boundaries so operators can reason about risk, uptime, and compliance.
-
Interoperability by design: Enable controlled interaction with other networks and public blockchains through standardized bridge components.
Who the stack is for
The Linea stack serves technical operators and infrastructure teams who:
- Need to run and operate their own Linea network
- Require privacy, governance, or regulatory controls not available on public networks
- Want production-capable infrastructure rather than experimental prototypes
- Are responsible for deployment, monitoring, maintenance, and incident response.
It assumes familiarity with distributed systems and blockchain infrastructure, but does not require deep protocol expertise.
