Polygon has recently open sourced its Chain Development Kit, a tool set that harnesses zero-knowledge proof (ZK-proof) technology to ensure security and fast finality for Ethereum’s ETH ecosystem. Jordi Baylina, technical lead of Polygon Hermez zkEVM, spoke to Cointelegraph about the new tool set, which is publicly available on a Github repository. According to Baylina, the tool set enables developers to launch a ZK-powered Layer 2 on Ethereum, tailored to the requirements of their project. It also provides automatic access to liquidity across all of Polygon’s chains as well as the wider Ethereum ecosystem.Baylina also highlighted the customizability of CDK for different appchains, featuring customizations for rollup or validium mode, zkEVM or another ZK-powered execution environment, various data availability solutions, native token and gas token customization, centralized or decentralized sequencer mode as well as permissioned networks with granular allowlists.The importance of ZK-proof technology is another factor that Baylina stressed, highlighting Polygon Labs’ belief that zero-knowledge is the future of scaling Ethereum. Chains launched with Polygon CDK are automatically connected to a shared ZK bridge and plugged into an “interop layer,” which is a cross-chain communication protocol. This unlocks sub-minute cross-chain transactions and creates the perception of a single chain environment.Baylina also compared CDK to other Ethereum ecosystem programming languages like Zk-proof pioneers StarkWare’s Cairo codebase. He finished by reaffirming the belief in ZK-proofs as the future of Ethereum scalability given its fast finality and withdrawal times, when compared to week-long delay by fraud proofs that feature in Optimistic rollup L2 solutions.
