Mechanism

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.

Powerful and trustless

Ethereum-level security guaranteed by zk-SNARKs
High throughput of 2000 TPS
Non-custodial architecture
Full ownership and control of assets (censorship resistant)
Data availability on Ethereum mainnet

The only decentralized zk-rollup

Fully open source and community-driven
Seamless integration with Hermez REST API
Permissionless network of coordinators
Decentralised auction model with validation reward token
Strategy towards governance minimisation

Token transfers simplified

Simple web and mobile app wallet
Low-cost token transfer
Atomic swaps
Fees payable in a single currency
Fast capital-efficient exit (withdrawal) in a few minutes

ARCHITECTURE

Layer 2 scalability solution

Computational integrity and on-chain data availability are guaranteed by zero-knowledge proof technology while preserving the public blockchain properties of Ethereum.
