[Taiko](https://taiko.xyz/) — decentralized Ethereum-equivalent ZK-EVM and general-purpose ZK-Rollup. Its purpose is to allow developers and users of dApps developed for Ethereum L1 to be used on Taiko without any changes. As a result, dApps can be easily deployed to L2, inheriting Ethereum’s security while incurring lower transaction fees than on L1.

Taiko scales Ethereum in a manner that emulates Ethereum as closely as possible — both technically and non-technically. More specifically, Taiko is an Ethereum-equivalent ZK-Rollup, scaling Ethereum by supporting all EVM opcodes in a layer-2 architecture that is decentralized, permissionless, and secure.

Taiko has been committed to building in the open, and our GitHub has reflected this for some time with everything being open source. In that vein, this public testnet is as open as the Taiko team can make it. It is open to all developers to deploy contracts on, all users to test out, and all willing participants to run an L2 node and propose blocks.
