Polygon, an Ethereum scaling firm, has released a Chain Development Kit (CDK) to help developers build blockchains powered by zero-knowledge (ZK) proofs. The open-source codebase will allow developers to create customizable layer 2 chains that are interoperable with each other, forming what Polygon is calling the “Value Layer.” “The goal is simple: build the Value Layer of the Internet, a core protocol that makes creating, sending, and receiving value of any kind as seamless and functional as sending or receiving information over the Internet,” said Polygon in a press release.
The CDK is the latest in a series of ZK-powered toolkits released by other layer 2s, such as Matter Labs’ zkSync and Starkware’s Starknet. Polygon has also released a toolkit for developers to create application-specific chains, called “Supernets.”
The CDK is the next evolution of Polygon’s technology roadmap, as it uses ZK proofs and “all existing Supernets can upgrade current architecture to leverage the industry-leading ZK technology of Polygon,” the company said.
