Introducing Polygon’s Type 1 Prover: Unlocking Zero-Knowledge Proof Functionality on Ethereum

Polygon has developed an open-source prover that enables Ethereum chains to become ZK layer 2s.

🌐 Polygon, the popular Ethereum scaling protocol, has unveiled its groundbreaking Type 1 prover, which enables ecosystem chains like optimistic rollups to access zero-knowledge proof (ZK-proofs) layer-2 functionality. 🚀

In an exclusive interview with Blocking.net, Polygon co-founder Brendan Farmer shed light on the development of this technology. Created in collaboration with Toposware, the Type 1 prover has been in the works for a year. It now empowers users to generate ZK-proofs for mainnet Ethereum blocks at an average cost of $0.002 to $0.003 per transaction. The best part? It’s dual licensed under MIT and Apache 2.0 and available on GitHub, ensuring accessibility for all Ethereum ecosystem participants.

Unleashing the Power of ZK-proofs

Before delving into the details, let’s understand what a Type 1 prover really means. Farmer affectionately referred to it as the “final form of a zkEVM.” Put simply, it allows any existing chain (be it Ethereum layer 1, an optimistic rollup, or an alternative L1) to be upgraded to a zkEVM L2, enabling it to seamlessly connect with Ethereum and Polygon’s aggregation layer. This revolutionary development allows the upgraded chain to actively participate within the Polygon ecosystem on a trustless basis. Talk about unleashing the power of ZK-proofs! 💪

What’s fascinating is that the Polygon team managed to defy industry expectations while developing this technology. Previously, skeptics believed that a layer-1 prover would not be practical and would come with exorbitant costs. However, Polygon has crushed those doubts. Farmer proudly proclaimed, “We’re proving real mainnet Ethereum blocks at an average cost of two- to three-tenths of a cent per transaction. I think that that’s orders of magnitude lower than what people were expecting.” It’s a game-changer!

The Ripple Effect on the Ethereum Ecosystem

So, what does this technological marvel mean for the broader Ethereum ecosystem? Farmer explained that the Type 1 prover allows the generation of ZK-proofs for any Ethereum Virtual Machine (EVM) chain. This has massive implications. Not only does it open doors for greater innovation and experimentation, but it also serves as a public good by alleviating the burden of maintaining a full node for users and services.

“Imagine a world in which we actually generate proofs for Ethereum L1, and instead of having to run a full node, you can verify a zero-knowledge proof like in your browser. And so, you’re getting full node security guarantees without actually having to run a node and deal with kind of the hassle and headache,” Farmer enthused. 🌍🔐

Optimistic Rollups Embrace the Type 1 Prover

The benefits of the Type 1 prover extend beyond the Ethereum layer 2 (L2) landscape, particularly to optimistic rollups. For those unaware, optimistic rollups are popular Ethereum L2 protocols that bundle transactions off-chain and submit proofs to the mainnet. However, one drawback of these rollups is the seven-day period during which funds are locked up.

On this front, Farmer shared some exciting news: “We see a lot of optimistic rollups choosing to use this prover and join the Polygon ecosystem because it’s a much better user experience. If you look at the cost that users pay to use third-party bridges to avoid the seven-day withdrawal delay, it’s a tremendous cost in aggregate, like eight figures. Being able to avoid that and to provide a more capital-efficient solution for users is a huge advantage.” Now that’s a game-changer for the world of rollups! 💸

The Ethos of Open Source

But why did Polygon make this technology open source? Farmer believes that transparency and accessibility align with the core ethos of Ethereum. “Our view is that if you want to look at who’s aligned with Ethereum, look at what they do, not what they say. We think that this is a huge public good, and it’s something that should be open source and should be available to anyone,” Farmer said.

Future Outlook and Investment Recommendations

With the unveiling of the Type 1 prover, the future of Ethereum scaling looks brighter than ever. As we witness the continued innovation and maturation of layer 2 solutions, the Ethereum ecosystem and its users stand to benefit immensely. The ability to unlock the power of zero-knowledge proofs while enjoying greater scalability and cost efficiency presents tremendous potential for developers, businesses, and investors alike. Keep an eye on the evolving landscape in the coming months! 🔍💡

Q&A: Addressing Your Concerns
