#show-card ## Overview [[Linea]] is a [[Layer 2]] (L2) scaling solution for [[Ethereum]], developed by ConsenSys. It aims to provide a developer-friendly, EVM-equivalent environment with significantly lower transaction costs and faster throughput than Ethereum [[Layer 1]]. Linea utilizes zk-[[Rollup]] technology, specifically a type of zkEVM, to achieve its scalability and security goals. - **Problem Solved:** High [[Gas|gas]] fees and limited throughput on Ethereum L1, making it difficult for some applications to scale and for users to transact affordably. - **Value Proposition:** Offers [[EVM]] equivalence (making it easy to migrate existing Ethereum [[DApp|dApps]]), the security benefits of zk-Rollups (cryptographic validity proofs), and backing from ConsenSys, a major Ethereum development company. - **Official Website:** [https://linea.build/](https://linea.build/) - **Status:** Live on mainnet. ## Key Features - **zk-Rollup (zkEVM Type 2):** Bundles transactions off-chain and generates cryptographic proofs (validity proofs, specifically ZK-SNARKs) to attest to their correctness on Ethereum L1. Aims for a high degree of EVM compatibility. - **EVM Equivalence:** Designed to allow developers to deploy existing [[Solidity]] [[Smart contract|smart contracts]] and use familiar Ethereum tooling with minimal changes. - **ConsenSys Ecosystem Integration:** Benefits from ConsenSys's suite of developer tools and infrastructure, including [[MetaMask]], [[Infura]], and Truffle. - **Focus on Developer Experience:** Prioritizes ease of use and seamless migration for Ethereum developers. - **Quantum-Resistant Cryptography:** Linea uses the Vortex ZK-proof system, which employs lattice-based cryptography for its prover, aiming for future-proofing against quantum computing threats. ## Technology - **Blockchain/Platform:** Layer 2 zk-Rollup built on Ethereum. - **Architecture:** Sequencer orders and batches transactions, a prover generates validity proofs for these batches, and these proofs are submitted to Ethereum L1 for verification. - **Core Mechanism:** zkEVM (Zero-Knowledge Ethereum Virtual Machine) that executes smart contracts compatibly with the EVM and uses ZK-SNARKs for proofs. ## Ecosystem & Use Cases - **Target Audience:** Ethereum developers, dApps seeking scalability, [[DeFI|DeFi]] users, [[NFT]] projects. - **How It's Used:** Deployment of a wide range of dApps, including DeFi, NFTs, gaming, and social applications, benefiting from lower fees and faster transactions. ## Getting Started & Resources - **Access:** Users can interact with Linea by adding the Linea Mainnet network to EVM-compatible [[Wallet|wallets]] and using bridges to transfer assets. - **Documentation:** [https://docs.linea.build/](https://docs.linea.build/) - **Community:** Active on Discord, Twitter, and other social channels. - **Bridge:** [https://bridge.linea.build/](https://bridge.linea.build/) ## Related Concepts - Ethereum - EVM - Rollup
