Ethereum layer-2 scaling protocol Polygon (MATIC) is finishing up efficiency testing of zero-knowledge rollup (zk rollups) know-how forward of full integration with its mainnet.

The event of the know-how, known as Polygon zkEVM (Ethereum Digital Machine), has been ongoing for over three years by the Polygon Hermez staff. The staff has already confirmed that zero-knowledge proofs are attainable on Ethereum, by producing over 12,000 zk-proofs in a major model of the zkEVM testnet.

David Schwartz, undertaking lead of Polygon zkEVM and PolygonID, unpacked the event of the performance in correspondence with Cointelegraph. Layer-2 platforms have continued to evolve and enhance performance which has performed a key position in driving Ethereum’s scalability.

As he defined, zero-knowledge rollups have elevated the pace at which layer-2 platforms can obtain finality whereas guaranteeing safe validation of transactions with zero-knowledge know-how. In blockchain phrases, finality is the purpose at which a block of transactions is taken into account to have been completely and irreversibly added to the blockchain:

“Lastly, now we have zkEVMs, reminiscent of Polygon zkEVM, that provide all of the above along with the equivalence to Ethereum Digital Machine with its superior strategies of zk-STARKs and zk-SNARKs.”

In keeping with Schwartz, Polygon zkEVM contains the primary full supply code obtainable EVM-equivalent zkProver, which passes all Ethereum vector assessments at over 99%. He described the completion of validity proofs for typical consumer transactions as “probably the most difficult and rewarding effort” since his staff started creating its native zkEVM.

Two years in the past, the Polygon staff estimated that creating zk rollups with EVM compatibility would take as much as ten years. Given the strides made, the staff describes zkEVM as the top recreation, combining advances with layer 2 scalability and quick finality. This presents a myriad of advantages to customers when including higher throughput and decrease charges.

Cointelegraph additionally queried the distinction between Polygon zkEVM and fellow Ethereum layer-2 scaling community StarkNet’s proprietary ZK-SNARK and ZK-STARK know-how. As beforehand reported, ZK-STARKS (Zero-Information Scalable Clear Argument of Information) primarily will increase scalability by batching hundreds of transactions with a single proof to verify validity on chain.

Schwartz mentioned the principle distinction between the initiatives is that zkEVM focuses on natively scaling the Ethereum ecosystem as a substitute of different zk-rollups simply scaling transactions and enhancing efficiency in a distinct VM format.

Polygon’s method purports to satisfy the classification of a kind 2 zkEVM described by Ethereum co-founder Vitalik Buterin in August 2022. As per Buterin’s abstract, kind 2 zkEVMs intention to be absolutely suitable with current purposes, however make minor modifications to Ethereum for simpler improvement and quicker proof technology. Schwartz added:

“In distinction, StarkNet is positioned as a Sort 4, introducing a brand new high-level language and requiring transpilers to translate solidity code into their language.”

On the similar time, Schwartz welcomed the chance to have extra benchmarks and supply code obtainable from different initiatives in an effort to be taught from completely different approaches. Exercise on Ethereum layer-2 options continues to develop, with blockchain data showing that transaction quantity Arbitrum and Optimism overshadowed transactions on the Ethereum mainnet going into 2023.
