Overview

Lineth​

Lineth (formerly the Linea Stack) is the collection of protocol components, onchain contracts, and operational capabilities used to deploy and operate networks built on Lineth. Lineth 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.

For how Lineth relates to the public Linea network, see Linea and Lineth.

Why Lineth exists​

Configurable

Lineth 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, Lineth 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.

Lineth lets you run an Ethereum-equivalent network tailored to enterprise requirements, using open source technology, while remaining anchored to the same protocol foundations as Linea Mainnet. The interoperability between Linea and Ethereum allows networks built on Lineth to use Ethereum's digital assets and build within the open and modular DeFi ecosystem.

What Lineth provides​

At a high level, Lineth provides:

  • Low-cost transactions: 10× cheaper than Ethereum L1 costs.

  • Fast transactions: Linea's 1s block times support near-instant soft finality.

  • Trustless Ethereum interoperability: Access Ethereum's deep liquidity via Linea's trustless rollup architecture.

  • An Ethereum-compatible execution environment: Run an Ethereum-equivalent network.

  • Composability: Leverage a trustless bridge to 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​

Lineth serves technical operators and infrastructure teams who:

  • Need to run and operate their own network built on Lineth
  • 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.
