According to BlockBeats, Polygon Labs has released a software tool called Chain Development Kit (CDK) that allows developers to develop a layer 2 chain for Ethereum supported by zero-knowledge proofs. Layer 2 blockchains deployed using its CDK will be able to connect to a shared ZK bridge to achieve interoperability. The code base of CDK will be open source.

The tool will be available as part of the Polygon 2.0 roadmap, which is set to launch next year and is designed to provide a framework for developing layer 2 blockchains that can run on the Ethereum network.
