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. → Learn about [Linea's architecture](/protocol/architecture) ## 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 Using zk proofs ensures user funds are always available and can be withdrawn instantly and at no cost. → Learn about how proofs fit within [Linea's transaction lifecycle](/protocol/architecture#transaction-lifecycle) ## 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. → Learn about the small differences between building on [Ethereum and Linea](/network/overview/ethereum-differences) ## Fast finality Soft finality within 1s because Linea has short block times and does not reorg confirmed L2 transactions. → Learn about Linea's [finality lifecycle](/network/overview/transaction-finality) ## Predictable pricing Clarity over Linea prices for transactions, how to estimate fees, and how Layer 1 and Layer 2 costs are accounted for. → Learn about Linea's [pricing strategy](/network/overview/predictable-pricing) ## Recoverable state Dedicated plugin to reconstruct Linea's state as it was at the last point in time data was finalized. → Learn about [recovering state](/network/overview/recoverable-state) ## Scale with MetaMask Linea is the best way for application developers to leverage MetaMask's products and distribution. Seamlessly integrate Linea through the MetaMask Developer portal, unlock easy on-ramping, bridging and swaps for your users, and access millions of the most engaged onchain users worldwide.
