Ethereum Scaling Solutions

Scalable payments, with Zero-Knowledge Rollups.

Hermez is an open-source zk-Rollup optimised for secure, low-cost and usable token transfers on the wings of Ethereum.

Ethereum Scalability and ZK-Rollups

Hermez zk-rollup is a layer 2 construction on top of Ethereum that solves its scalability through mass transfer processing rolled into a single transaction. The "zero-knowledge proof" (ZK) technology is used to present and publicly record the validity and correctness of the rolled transfers processed on the Ethereum blockchain. By storing just the proof and the compressed data of a batch of transfers, the efficiency and the throughput of the network is multiplied.
