The Ethereum ecosystem might welcome quite a lot 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 guarantee safety and quick finality.
Jordi Baylina, co-founder and technical lead for Polygon, spoke to Cointelegraph solely concerning the new toolset, which is publicly out there on a GitHub repository:
“The motivating concept is straightforward: 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 challenge.”
In accordance 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, with out fragmenting liquidity.”
The Ethereum developer pointed to plenty of totally different initiatives constructing CDK-powered chains throughout quite a lot of use instances, 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 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. 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 instantly to Ethereum. As an alternative, the interop layer will obtain proofs from chains and submit a single ZK-proof that proves the state of all Polygon chains.”
Baylina mentioned 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 automated entry to shared liquidity by means of a ZK bridge and interop layer of an L2 ecosystem secured by working ZK-proofs.
He completed by reaffirming the assumption in ZK-proofs as the way forward for Ethereum scalability given its quick finality and withdrawal instances, in comparison with week-long delays by fraud proofs that function in optimistic rollup L2 options.
“ZK makes higher bridges but additionally secures chains by rigorous math, and not using 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 good contract blockchain.
