- Polygon has developed an open-source “zkEVM” prover that allows Ethereum chains to adopt zero-knowledge proof-based layer 2 functionality, unlocking new privacy capabilities
- The zkEVM prover enables generating low-cost ZK-proofs for Ethereum blocks, allowing chains to become zkEVM layer 2s that provide node security without running full nodes
- Polygon open sourced the prover to align with Ethereum’s ethos of open collaboration, viewing it as an Ethereum public good that benefits the whole ecosystem
Polygon, an Ethereum scaling solution, has developed an open-source “zkEVM” prover that enables Ethereum Virtual Machine (EVM) chains to adopt zero-knowledge (ZK) proof-powered layer 2 functionality. This technology unlocks new privacy capabilities for Ethereum ecosystem blockchains.
Polygon’s zkEVM Prover Enables Private EVM Chains
The zkEVM prover allows generating ZK-proofs for mainnet Ethereum blocks at an average cost of 0.02-0.03 cents per transaction. Polygon co-founder Brendan Farmer stated this prover disproves claims that layer 1 provers are impractical due to cost.
Farmer explained that the prover upgrades any EVM chain into a zkEVM layer 2 that connects to Ethereum’s layer 1. This allows users to verify proofs instead of running full nodes, providing “full node security guarantees without the hassle.”
Optimistic Rollups Can Adopt zkEVM Prover
A key benefit is that optimistic rollups, which bundle transactions off-chain, can leverage the prover. This eliminates the need for a 7-day withdrawal waiting period, improving capital efficiency.
Polygon Views Prover as an Ethereum Public Good
Polygon opted to open source the prover because it aligns with Ethereum’s ethos of open collaboration. Co-founder Jordi Baylina said amalgamating Polygon’s scaling networks will complete its cross-chain Polygon Zero protocol in 2024.
In summary, Polygon’s zkEVM prover enables private, low-cost layer 2s for Ethereum chains. By open sourcing this technology, Polygon aims to contribute an Ethereum public good benefiting the entire ecosystem.
