Linea
Consensys-built zkEVM offering Ethereum scaling with MetaMask integration
Technology Stack
Introduction to Linea
Linea is a zkEVM Layer 2 built by Consensys, the company behind MetaMask, Infura, and other essential Ethereum infrastructure. This pedigree gives Linea unique advantages: native MetaMask integration, Infura infrastructure, and a team deeply embedded in the Ethereum ecosystem.
Launched in 2023, Linea provides EVM bytecode compatibility with the security benefits of zero-knowledge proofs. The Consensys backing provides resources and distribution advantages that independent zkEVMs cannot match.

Conclusion
Linea benefits from unique positioning as Consensys’s zkEVM, with native MetaMask integration reaching millions of users. This distribution advantage is significant in a crowded L2 market.
The lack of token creates uncertainty but also simplifies the value proposition—users can access zkEVM scaling through familiar MetaMask interface without additional complexity.
For users already in the MetaMask ecosystem and for developers wanting Consensys-quality infrastructure, Linea provides accessible zkEVM scaling. Success depends on token clarity, decentralization progress, and leveraging the Consensys ecosystem effectively.
