Overview
Linea is a secure, low-cost, and Ethereum-equivalent layer 2 blockchain built to bring the world onchain without compromising on security and decentralization.
Linea has been 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 zero-knowledge (zk) proofs, Linea removes the seven-day lockup period associated with fraud proofs in other layer 2 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 Using zk proofs ensures user funds are always available and can be withdrawn instantly and at no cost.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 layer 2 network fully compatible with the Ethereum Virtual Machine (EVM). This means that any Ethereum-based projects and assets can be seamlessly deployed on and bridged to Linea without any code base changes.
