# Solution Overview

Ryoshi is built using the Polygon CDK. Polygon Chain Development Kit (CDK) is a modular, open source software toolkit for blockchain developers which supports the installation and configuration of a variety of chain architectures. Polygon CDK empowers developers to launch new L2 chains running the Polygon zkEVM technology on Ethereum or, in the future, transition existing Layer 1 chains into ZK-EVM L2s.

Ryoshi is a decentralized Ethereum Layer 2 network that offers a secure and user-friendly blockchain experience to all, using advanced cryptographic zero-knowledge proofs to provide validity and near-instant finality to off-chain transaction computations.
