Hermez Network (HEZ)

What is Hermez Network (HEZ)?

Hermez Network (HEZ) is a decentralized, open-source zk-rollup (zero-knowledge rollup) solution built on top of the Ethereum blockchain. It aims to significantly improve the scalability of Ethereum by bundling numerous transactions into a single, verifiable proof, thereby reducing transaction costs and increasing throughput. Founded on October 15, 2020, and based in Zug, Switzerland, Hermez Network focuses specifically on scaling payments and token transfers, addressing a critical need in the Ethereum ecosystem. The project is developed by idem3, a team dedicated to building innovative decentralized solutions.

Unlike many other scaling solutions, Hermez emphasizes a unique mechanism for selecting block creators, setting it apart from traditional methods. This mechanism, known as proof-of-donation, involves a burn auction where potential block creators bid for the right to produce the next block. A substantial portion (40%) of the winning bid is then redirected to Ethereum public goods through Gitcoin quadratic funding grants. This innovative approach not only secures the network but also actively supports the broader Ethereum ecosystem, aligning the incentives of network participants with the overall health and development of the platform. The zk-rollup technology combined with the proof-of-donation mechanism positions Hermez as a significant player in the layer-2 scaling landscape.

Hermez’s commitment to decentralization and its focus on supporting Ethereum public goods make it an attractive option for users and developers looking for a scalable and ethical solution. By leveraging zero-knowledge proofs, Hermez ensures that transactions are verified without revealing sensitive information, enhancing privacy and security. The network’s architecture is designed to be permissionless and trustless, allowing anyone to participate in the network and contribute to its growth. This focus on community involvement and open-source development further strengthens Hermez’s position as a leading zk-rollup solution on Ethereum.

How Does Hermez Network Work?

Hermez Network operates as a zk-rollup, an off-chain scaling solution that bundles multiple transactions into a single proof before submitting it to the Ethereum mainnet. This approach significantly reduces the burden on the Ethereum blockchain, resulting in faster transaction speeds and lower gas fees. The process begins with users submitting transactions to Hermez’s layer-2 network. These transactions are then aggregated and processed by a sequencer, which is responsible for creating a zk-SNARK (zero-knowledge succinct non-interactive argument of knowledge) proof that verifies the validity of the bundled transactions. This proof is then submitted to the Ethereum mainnet, along with the state changes resulting from the transactions.

The core of Hermez’s functionality lies in its use of zero-knowledge proofs, which allow the network to verify transactions without revealing the underlying data. This is achieved through complex cryptographic algorithms that ensure the integrity of the transactions while maintaining user privacy. The zk-SNARK proof submitted to the Ethereum mainnet is significantly smaller than the combined size of the individual transactions, resulting in substantial savings in gas fees. Moreover, the verifier contract on Ethereum can quickly verify the proof, confirming the validity of the bundled transactions without needing to re-execute them. This process dramatically improves the efficiency and scalability of Ethereum.

A key differentiator for Hermez is its innovative proof-of-donation mechanism. Instead of a traditional Proof-of-Stake or Proof-of-Work consensus, Hermez utilizes a permissionless auction system where different participants (coordinators) bid to be the sequencer for a given period. The highest bidder gets the right to order transactions into a batch and submit the zk-SNARK proof. However, a significant portion (40%) of the winning bid isn’t simply pocketed by the winning coordinator; it’s donated to the Ethereum ecosystem through Gitcoin quadratic funding grants. This mechanism incentivizes coordinators to participate while simultaneously supporting the development of public goods on Ethereum. This unique approach fosters a virtuous cycle, where the success of Hermez directly contributes to the growth and sustainability of the Ethereum ecosystem.

Hermez Key Features and Technology

Hermez Network boasts several key features and technological innovations that set it apart from other layer-2 scaling solutions. At its core is the use of zk-rollups, which provide a highly efficient and secure way to scale Ethereum transactions. The technology ensures that transactions are verified off-chain, reducing the computational burden on the mainnet while maintaining the security guarantees of Ethereum. The use of zk-SNARKs allows for the creation of concise proofs that can be quickly verified on-chain, minimizing gas costs and maximizing throughput.

The Proof-of-Donation consensus mechanism is another defining feature of Hermez. This innovative approach to block creation not only secures the network but also actively supports the Ethereum ecosystem. By donating a substantial portion of the winning bid to Gitcoin quadratic funding grants, Hermez ensures that its success directly contributes to the development of public goods and infrastructure on Ethereum. This mechanism aligns the incentives of network participants with the overall health and growth of the platform, fostering a collaborative and sustainable ecosystem.

Furthermore, Hermez is designed to be fully decentralized and permissionless, allowing anyone to participate in the network. The open-source nature of the project encourages community involvement and collaboration, driving innovation and ensuring the long-term sustainability of the network. The architecture of Hermez is carefully crafted to minimize trust assumptions, ensuring that users retain control over their funds and data. This commitment to decentralization and transparency makes Hermez a compelling option for those seeking a scalable and ethical solution for Ethereum transactions. The network is also designed to be interoperable with other Ethereum-based applications and protocols, allowing for seamless integration and composability within the broader DeFi ecosystem.
