The Ethereum ecosystem might welcome a wide range of new layer 2 (L2) protocols constructed on Polygon’s newly launched open-source codebase, Chain Improvement Equipment, which harnesses zero-knowledge proof (ZK-proof) expertise to make sure safety and quick finality.
Jordi Baylina, technical lead of Polygon Hermez zkEVM, spoke to Cointelegraph solely in regards to the new toolset, which is publicly out there on a GitHub repository:
“The motivating thought is easy: It needs to be simple and seamless for builders to launch a ZK-powered layer 2 on Ethereum, tailor-made to the necessities of their venture.”
Based on Baylina, a key facet is that Polygon CDK permits computerized entry to liquidity throughout all of Polygon’s chains in addition to the broader Ethereum ecosystem, offering “on-demand scale, with out fragmenting liquidity.”
The Ethereum developer pointed to quite a few 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 setting, varied knowledge availability options, native token and fuel 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 careworn, highlighting Polygon Labs’ perception that zero-knowledge is the way forward for scaling Ethereum. Because 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 millions of chains within the Polygon ecosystem. It’s inefficient for every of those to submit their proofs on to Ethereum. As a substitute, the interop layer will obtain 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 setting.
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 computerized entry to shared liquidity via 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 occasions, compared with week-long delays by fraud proofs that characteristic in optimistic rollup L2 options.
“ZK makes higher bridges but additionally secures chains by rigorous math, with out a want for social-economic parts 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.
