The Ethereum ecosystem might welcome a wide range of new layer 2 (L2) protocols constructed on Polygon’s newly launched open-source codebase, Chain Development Kit, which harnesses zero-knowledge proof (ZK-proof) expertise to guarantee safety and quick finality.
Jordi Baylina, co-founder and technical lead for Polygon, spoke to Cointelegraph completely concerning the new toolset, which is publicly out there on a GitHub repository:
“The motivating idea is simple: It should be easy and seamless for developers to launch a ZK-powered layer 2 on Ethereum, tailored to the requirements of their project.”
According to Baylina, a key side is that Polygon CDK permits automated entry to liquidity throughout all of Polygon’s chains in addition to the broader Ethereum ecosystem, offering “on-demand scale, without fragmenting liquidity.”
The Ethereum developer pointed to a variety of totally different initiatives constructing CDK-powered chains throughout a wide range of use circumstances, together with payment-specific L2s, decentralized finance, gaming, social-specific platforms, and creator or nonfungible token platforms.

Baylina additionally highlighted the customizability of CDK for various appchains, that includes customizations for rollup or validium mode, zkEVM or one other ZK-powered execution atmosphere, varied information availability options, native token and gasoline token customization, centralized or decentralized sequencer mode in addition to permissioned networks with granular allowlists.
The significance of ZK-proof expertise is one other issue Baylina harassed, highlighting Polygon Labs’ perception that zero-knowledge is the way forward for scaling Ethereum. As the Hermez zkEVM lead explains, chains launched with Polygon CDK are mechanically linked to a shared ZK bridge and plugged into an “interop layer,” which is a cross-chain communication protocol.
“Suppose there are thousands of chains in the Polygon ecosystem. It’s inefficient for each of these to submit their proofs directly to Ethereum. Instead, the interop layer will receive proofs from chains and submit a single ZK-proof that proves the state of all Polygon chains.”
Baylina stated the expertise unlocks sub-minute cross-chain transactions and creates the notion of a single-chain atmosphere.
Cointelegraph additionally requested about the important thing variations between CDK and different Ethereum ecosystem programming languages like ZK-proof pioneer StarkWare’s Cairo codebase.
Baylina defined that the structure unlocked by Polygon CDK is totally different in that it permits automated entry to shared liquidity by way of a ZK bridge and interop layer of an L2 ecosystem secured by working ZK-proofs.
He completed by reaffirming the idea in ZK-proofs as the way forward for Ethereum scalability given its quick finality and withdrawal instances, when put next with week-long delays by fraud proofs that characteristic in optimistic rollup L2 options.
“ZK makes better bridges but also secures chains by rigorous math, without a need for social-economic components required by fraud proofs.”
Cointelegraph beforehand explored the Ethereum layer-2 ecosystem, unpacking the fundamentals of Ethereum rollups and the totally different approaches to scaling the sensible contract blockchain.
