**What is Linea?**

*   Linea is a fully EVM-compatible Layer-2 (L2) protocol that runs as a ZK-rollup.
    
*   It empowers developers by allowing them to build on top of Ethereum while benefiting from the scalability and security features of ZK-rollups.
    
*   The fact that Linea implements a fully EVM-compatible ZK-rollup is significant because it dramatically enhances developers' abilities to create decentralized applications (dApps) on the Ethereum network.
    

**Key Features of Linea:**

*   Secure zkEVM Ecosystem: Linea delivers unrivaled network security with its cryptographically secure zk infrastructure, comprehensive security partnerships, and security-oriented ecosystem culture.
    
*   Robust Security System: Linea leverages quantum-resistant lattice-based cryptography alongside a recursion-friendly zkSNARK prover, formal verification, and diverse clients.
    
*   Web3 Projects: Linea hosts exciting and innovative web3 projects, making it home to the most secure and cutting-edge developments in the Ethereum ecosystem.
    
*   Bootstrapped by ConsenSys: While committed to decentralization, Linea is bootstrapped by ConsenSys—one of the strongest forces behind Ethereum's development.
    

**Mission and Vision:**

*   Linea's mission is to make the decentralized internet safe and accessible for everyone.
    
*   They encourage web3 education, exploration, and expertise through ecosystem activations.
    
*   Linea aims to be the go-to platform where dApps thrive, revolutionizing various domains such as decentralized finance (DeFi), gaming, social media, and more
    

**How Linea Works:**

*   Linea operates as a ZK-rollup, bundling transactions into batches executed off-chain.
    
*   ZK-rollup operators submit a summary of changes required to represent all transactions in a batch, along with validity proofs.
    
*   The ZK-rollup's state is maintained by a smart contract deployed on the Ethereum network.
    
*   Validity proofs ensure correctness, allowing finalization of transactions on Ethereum without delays.
    
*   Linea compresses transaction data using techniques like representing accounts by index rather than address, reducing fees for users.
