Linea Mainnet
Linea Mainnet is the public, permissionless zkEVMzkEVM A virtual machine that executes smart contracts and proves the correctness of execution using zero-knowledge proofs. zkEVMs recreate aspects of Ethereum's design, which provides an "Ethereum-like" experience for developers and users. L2Layer 2 (L2) A separate blockchain that increases transaction speed and throughput, while deriving its security from Ethereum. L2s rely on Ethereum for data availability by posting their transaction data onto Ethereum. network built on LinethLineth (Formerly the Linea Stack) The open-source ZK-rollup stack, codebase, and technical protocol that's the foundation of Linea Mainnet. Operators can deploy this stack to launch their own Ethereum-compatible L2 or L3 networks.. Linea processes Ethereum-compatible transactions, generates ZK proofsZero-knowledge proof A cryptographic method that allows an individual to prove that a statement is true without conveying any additional information. This is useful for scaling blockchain networks through rollups, because it reduces the amount of information you have to provide to lower layers., and finalizes state to Ethereum.
Get started building on Linea:
Deploy a smart contract to Linea
Launch your first contract using your preferred tooling.
Bridge tokens to Linea
Move ETH and other tokens between Ethereum and Linea.
Run a node
Sync and operate a Linea node with your preferred client.
Recover state from the public network
Reconstruct Linea's state independently of the operator.
For protocol mechanics, see how the Lineth protocol works.
Linea is incubated within Consensys. Our mission is to empower developers to build the next generation of decentralized applications and onboard the next billion users to web3.
Security for all
Built as a layer above Ethereum, Linea inherits the robust security and decentralization of the Ethereum network while significantly increasing throughput and reducing transaction fees to negligible amounts.

Advanced zero-knowledge proof technology
By leveraging ZK proofs, Linea removes the seven-day lockup period associated with fraud proofsFraud proof In optimistic rollups, the evidence a verifier provides to question the validity of a batch of transactions. Depending on how they're executed, these proofs analyze a section of transactions and attempt to confirm their validity. in other L2 solutions built according to the optimistic rollup model. Using ZK proofs ensures user funds are always available and can be withdrawn instantly and at no cost.

True Ethereum equivalence
Linea supports all the features that Ethereum supports. It's the only zero-knowledge L2 network fully compatible with the EVMEthereum Virtual Machine (EVM) A stack-based virtual machine that executes bytecode. In Ethereum, the execution model specifies how the system state is altered given a series of bytecode instructions and a small tuple of environmental data. This is specified through a formal model of a virtual state machine.. This means that any Ethereum-based projects and assets can be seamlessly deployed on and bridged to Linea without any code base changes.

Fast finality
Soft finalitySoft finality The point at which a block is confirmed and committed on the L2 itself, before its state is committed on the finalization layer. On Linea Mainnet, soft finality is reached in about 1 second. within 1s because Linea has short block times and does not reorg confirmed L2 transactions.
