What is Suterusu (Suter)?

Suterusu is a project built upon the state-of-the-art cryptographic technologies zk-Consnark. Suterusu project CTO Dr. Huang Lin partners with cryptographers from Centre national de la recherche scientifique and Karlsruhe Institute of Technology co-authored a paper on a new efficient range proof scheme with transparent setup (accepted by a top Cryptography conference Eurocrypt 2021), which serves as the foundation of Suterusu protocol. Suterusu protocol can provide privacy protection for the users’ transaction data without comprising efficiency.

To date, Suterusu network has 47 node operators and over 158k mining participates, collectively over 80% staking rate. With 3,000 Suter token reward per 60s, the network generated over 2bn suter token rewards since launch which bring the total circulating supply to 3.7bn suter token. Private round investor’s token have been fully unlocked since Jan 2021, and the foundation’s token will be unlocked by the end of 2022.

What is Suter Shield?

Suter Shield is a decentralized, layer-2 solution for transaction and data-protection built on Ethereum, while also can be integrated with other layer-1 projects supporting smart contracts such as Binance Smart Chain, Heco etc.

It applies public key homomorphic encryption to protect the transactional amount and conceals the identities of the sender and receiver of a transaction among other system users through invoking zero-knowledge proof. In other words, Suterusu protocol not only provides anonymity for the involved parties and but also transactional confidentiality.

Suter Shield allows the sender of a transaction to arbitrarily select the target receiver of a confidential transaction without the need of sharing any secret with the receiver beforehand. Therefore, it is not only much more user-friendly, but it also provides a foundation to adapt to more sophisticated privacy-preserving DeFi functionalities such as DEX, insurance, loan, etc.

In addition, compared with other similar solution, Suter Shield not only facilitates the anonymous and confidential transactions of ETH and ERC-20 tokens, but it is also a much more modularized and universal privacy-protection solution for any smart-contract platforms, which is why we can easily transform our solutions to other platforms such as BSC or HECO. Furthermore, the Suter VM not only provides anonymous payment functionality for smart contract platforms but also anonymous BTC cross-chain functionality that will bring more liquidity to the Suter ecosystem.

Suterusu’s vision to provide privacy-protection for the users of all digital assets, therefore, Suterusu takes regulation compliance to its heart at the beginning of the system design. We apply blacklist and recursive blacklisting to ensure our system is regulation compliant. Any Suter transfer operation is required to compare the sender accounts of a transaction to the blacklist accounts. A transaction that involves any blacklist account will be rejected. This will guarantee the Suterusu ecosystem will effectively eradicate any misbehavior that is against the financial regulation, such as money launder.

Suter token is native governance and utility token. It’s a fixed-supply ERC-20 token that is used for the purpose of community growth and rewards for the users participating in the Suter DAO voting.
