Linea is a fully EVM equivalent zero-knowledge rollup (zk-rollup), designed to scale Ethereum with higher throughput and lowered transaction fees. Linea relies on an innovative, internally-built, lattice-powered prover which utilizes zkSNARK technology. It enables proofs to be generated quickly and yet does not require a trusted setup, which has long been a flaw of zkSNARK technology.
On Linea, transaction fees are expected to be 15X to 20X cheaper than on the Ethereum mainnet. In line with their history in building developer tooling and infrastructure, Linea is designed to be developer friendly, supporting ConsenSys’ MetaMask, Truffle and Infura natively. The chain is also designed to be composable and approachable, meaning that developers do not need to be zkEVM or zk-rollup experts to build on it.
