is performing performance testing of zero-knowledge rollup (zk-Rollups) technology prior to full integration with its main network.
The Polygon zkEVM (Ethereum Virtual Machine) technology has been developed by the Polygon Hermez team for more than three years. The team has already confirmed that zero-knowledge proofs are possible on Ethereum by generating over 12,000 zk-proofs in the primary version of the zkEVM testnet
David Schwartz, project lead for Polygon zkEVM and PolygonID, unpacked the development of the functionality in correspondence with Cointelegraph. The Layer-2 platform is constantly evolving and improving functionality to play a major role in promoting the scalability of Ethereum.
As he explained, the zero-knowledge rollup has increased the momentum that Layer 2 platforms can achieve finality by ensuring secure verification of transactions with zero-knowledge technology In the context of blockchain, finality is the point at which a of transactions The pieces are considered to be permanently and irreversibly connected For the blockchain:
“Finally we have zkEVMs, such as Polygon zkEVM, which provide all of the above in addition to equivalence to Ethereum virtual machines with advanced methods of zk-STARKs and zk-SNARKs.”
According to Schwartz, Polygon zkEVM includes the first complete source code EVM-equivalent zkProver available, which passes over 99% of all Ethereum vector tests. He described completing validity proofs of traditional user transactions as “an extremely challenging and rewarding endeavor” as his team began developing its core zkEVM

Two years ago, the Polygon team estimated that zk-Rollups with EVM compatibility would take up to ten years to develop. Given the progress made, the team describes zkEVM as the endgame, combining level-2 scalability with rapid advancement. This provides a myriad of benefits to users by adding greater throughput and lower fees.
Cointelegraph also questioned the difference between Polygon zkEVM and fellow Ethereum Layer-2 scaling network StarkNet’s proprietary ZK-SNARK and ZK-STARK technology as reported earlier, the zero-knowledge scalable transparent logic of knowledge , or zk-SNARKS, primarily increases transaction scalability with a proof to confirm the validity of thousands in chain batching

Schwartz said the main difference between the projects is that zkEVM focuses on scaling the Ethereum ecosystem natively rather than other zk-rollups by simply scaling transactions and extending performance to a different VM format.
The polygon approach aims to meet the classification of Type 2 zkEVM described by Ethereum co-founder Vitalik Buterin in August 2022. According to Buterin’s summary, Type 2 zkEVMs aim to be fully compatible with existing applications, but easier The development is to make small modifications to Ethereum and rapid proof generation. Schwartz continued.
“In contrast, StarkNet is positioned as Type 4, where a new high-level language is introduced and the transpiler needs to translate the solidity code into its own language.”
At the same time, Schwartz welcomes the chance to learn from different perspectives and has more benchmarks and source code available from other projects. As Ethereum Layer-2 solution activity continues to grow, blockchain data shows that transaction volume arbitrum and optimism have overshadowed transactions heading into 2023 on the Ethereum mainnet.
