There are many new L2s emerging in the web3 ecosystem with the goal of improving Ethereum’s scalability. These L2s use a variety of solutions to create layers on top of Ethereum that are faster, cheaper, and yet still benefit from the base Ethereum blockchain layer to secure transactions. Among this new set of layer two solutions, ZK-rollups (or zero-knowledge rollups) have risen to the top.
In this article, we’ll explore one of those solutions: Linea, launched by ConsenSys. Then, we’ll walk through a tutorial on how to build a dApp on the Linea testnet. Finally, we’ll create our own cryptocurrency on Linea using Solidity, MetaMask, and Truffle.
