Polygon, a protocol and framework for building and bridging Ethereum-compatible networks, has announced its integration with Mina Protocol, a blockchain firm working on privacy-preserving technology. The integration will bring Mina Protocol’s zero-knowledge proofs (specifically, zkSNARKs, or non-interactive zero-knowledge proofs) to the inter-operable Polygon blockchain, providing privacy-preserving technology to the blockchain’s aggregating and scalable network for a multi-chain Ethereum ecosystem.
