Linea is a type 2 Ethereum zero-knowledge virtual machine (zkEVM). zkEVM replicates the Ethereum environment as a roll and allows developers to build on it like on the Ethereum mainnet. Linea allows you to deploy any smart contract, use any tool, and develop as if you were building on Ethereum. For users, this allows for the experience and security guarantees of Ethereum, but at lower transaction costs.

Starting with the Ethereum genesis block, ConsenSys was formed to be the strongest decentralization force on the planet. The ConsenSys team believes that thanks to networks like Ethereum, humanity can achieve more. Their teams will manage the Linea project in the same way as other public goods, aiming for full decentralization and a commitment to open development.

Investments:

The project has raised $725 million in investments from tier-1 funds and giants such as Microsoft, SoftBank, Temasek and others.

Thoughts:

Our take on the ConsenSys zkEVM / Linea project is that it’s an interesting and innovative layer 2 solution for Ethereum that has received significant funding and has just launched its testnet. We believe that you really don’t want to miss testnets like this, and generous rewards may be given to early participants in this project. Overall, we are confident in the potential of ConsenSys zkEVM / Linea and its future success.
