Polygon develops open-source prover, permitting Ethereum chains to grow to be ZK layer 2s

Ethereum scaling protocol Polygon has developed a brand new Sort 1 prover permitting ecosystem chains like optimistic rollups to unlock zero-knowledge proof (ZK-proofs) layer-2 performance.

Polygon co-founder Brendan Farmer spoke solely to Cointelegraph after Polygon introduced that its next-generation Polygon zkEVM Sort 1 prover shall be out there as open supply to Ethereum ecosystem members.

Farmer mentioned the event of the expertise, which was constructed with the assistance of Toposware, was a 12 months within the making and unlocks the flexibility to generate ZK-proofs for mainnet Ethereum blocks at a mean price of $0.002 to $0.003 per transaction. The Sort 1 prover is twin licensed beneath MIT and Apache 2.0 and shall be out there on GitHub.

“A Sort 1 prover is sort of the ultimate type of a zkEVM. It permits us to take any current chain, whether or not it’s the Ethereum layer 1, an optimistic rollup or an alternate L1, we will improve that into zkEVM L2 that may join trustlessly to Ethereum and Polygon’s aggregation layer and take part within the Polygon ecosystem,” Farmer defined.

Benchmark knowledge of Polygon’s Sort 1 zkEVM prover and the related prices of proving layer-1 blocks from the Ethereum blockchain.

Farmer added that business members have traditionally advised {that a} layer-1 prover will not be sensible and can be cost-prohibitive. Nevertheless, the group has since managed to supply effectivity and value.

“We’re proving actual mainnet Ethereum blocks at a mean price of two- to three-tenths of a cent per transaction. I believe that that’s orders of magnitude decrease than what folks have been anticipating.”

The event has some attention-grabbing implications for the broader Ethereum ecosystem. Farmer defined that the expertise permits the era of ZK-proofs for any Ethereum Digital Machine (EVM) chain.

The Polygon co-founder added that the expertise serves as a public good for the Ethereum ecosystem by eradicating the necessity for customers and companies to keep up a full node.

“Think about a world by which we really generate proofs for Ethereum L1, and as an alternative of getting to run a full node, you’ll be able to confirm a zero-knowledge proof like in your browser. And so, you’re getting full node safety ensures with out really having to run a node and cope with sort of the effort and headache,” Farmer mentioned.

Polygon’s announcement outlines the framework of zkEVM initially proposed by Ethereum co-founder Vitalik Buterin. These rank from 1 to 4, reflecting the extent of compatibility with Ethereum and its EVM.

A Sort 1 prover is taken into account to have “the very best degree of compatibility with Ethereum,” permitting the era of proofs for EVM chains with modifications or migrations. These proofs protect execution logic like storage construction and hash features.

The expertise may even enable optimistic rollups, well-liked Ethereum L2 protocols that bundle transactions off-chain and submit proofs to mainnet, to faucet into the advantages of the Sort 1 prover. One broadly cited downside of optimistic rollups is a seven-day interval inside which funds are locked up.

“We see a variety of optimistic rollups selecting to make use of this prover and be a part of the Polygon ecosystem as a result of it’s a a lot better person expertise. For those who take a look at the fee that customers pay to make use of third-party bridges to keep away from the seven-day withdrawal delay, it’s an amazing price in combination, like eight figures,” Farmer defined.

“Having the ability to keep away from that and to supply a extra capital-efficient answer for customers is a big benefit.”

When questioned why Polygon opted to make the expertise open supply, Farmer mentioned that making the expertise out there to the broader ecosystem was in step with the “ethos” of Ethereum.

“Our view is that if you wish to take a look at who’s aligned with Ethereum, take a look at what they do, not what they are saying. We predict that this can be a enormous public good, and it’s one thing that must be open supply and must be out there to anybody,” Farmer mentioned.

Cointelegraph additionally spoke to Polygon co-founder Jordi Baylina in December 2023, who outlined the layer 2’s aim of amalgamating its scaling networks and expertise to finish its “Polygon 2.0” cross-chain coordination protocol in 2024.
