Polygon’s transition to zero-knowledge

December 14, 2021, 9:41AM EST • 9 min read Quick Take Polygon recently announced the acquisition of MIR protocol, a zk-SNARK rollup Polygon also recently launched Polygon Miden, the first open-sourced STARK-based rollup framework Polygon has previously started exploring the ZK-rollup space, with its acquisition of Hermez Network and partnership with EY for Polygon Nightfall Polygon’s PoS chain has seen increased adoption but this success may not translate directly for their suite of ZK solutions by the time they are …

Polygon acquires ZK-rollups startup Mir Protocol for $400 million

Polygon (formerly Matic Network) has made yet another acquisition in the ZK-rollups space, buying Mir Protocol for $400 million. Mir is an Ethereum scaling startup that utilizes zero-knowledge proof (ZK-proof) technology. A ZK-proof is a cryptographic tool that can be used to create ZK-rollups. ZK-rollups enable transactions to be processed but don’t require all transaction data to be posted on Ethereum. This helps to reduce the block space used on Ethereum — enabling it to scale — and reduces gas …
