Designed for collaborative economy

Polygon Hermez is giving back

Block creators are selected through a burn auction, however rather than burning tokens, 40% of the winning bid is returned as a donation to be reinvested in Ethereum public goods through Gitcoin quadratic funding grants. We call this mechanism Proof-of-Donation.

Permissionless auctions for validators

Anyone can bid in a decentralised auction to create the next batch on Polygon Hermez Network. Each successful validation is rewarded with the collected transaction fees.

HEZ Token

After Hermez Network merged with Polygon, the HEZ token has been indexed to MATIC token. Polygon's native token MATIC will become the utility token of the Polygon Hermez zkRollup.

Holders can exchange HEZ to MATIC here.

Future of payments

Zero-knowledge cryptography

Polygon 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.

Universal scalability with validity proofs

The consensus of status between Ethereum and Polygon Hermez is leveraging on zk-SNARKs validity proofs. Since validity is enforced by the zero-knowledge circuits, the L2 network status and the transactions can be considered as valid instantly once the corresponding block containing the proof is mined in L1.

All the data availability required to reconstruct the full state of Polygon Hermez Network is implemented on Ethereum, and so any permissionless node can be deployed and synchronized from it.
