Suterusu Shield is a trustless and universal layer-2 privacy-protection protocol that provides protection and privacy to transactions. The product operates as a private payment infrastructure for smart contract platforms. Further, the platform aims to develop and implement an on-chain (an activity that takes place on the blockchain) auction scheme that guarantees the fairness of on-chain auctions. The forum also seeks to extend its solutions to protect the payment privacy of non-fungible tokens (NFTs).

According to the whitepaper, web 3.0 has enabled every internet user to become the owner of their content, data, and assets. But, without a privacy protection infrastructure that can safeguard the users’ content, data, or digital assets from unwanted attention, it would not be possible for users to have complete control of their digital life. Hence, Suterusu seeks to play a vital role in protecting users’ privacy. 

While millions of transactions take place over blockchains, users have to expose individual privacy, which can lead to anyone knowing their address reading the user’s entire financial history. Thus, the protocol delinks the sender and receiver addresses, giving complete security to transaction data through advanced cryptography. The layer-1 or layer-2 miners would see only the encrypted data for all the transactions.

The Suter transfer functionality ensures a network of Suter accounts that obfuscates the flow of tokens in the Suter pool. Suter is the native token of the Suterusu Shield platform. In the auction scheme, the ecosystem protects the bidding price while the bidders’ committed tokens are locked for the entire auction period. In addition, the network guarantees no competitive conditions, as all the bidding prices will be encrypted and there are no time zone restrictions, no trust, etc.

The platform has developed an advanced ZK-ConSNARK scheme that provides constant size proof, efficient proof generation, and verification. Further, the forum has built various derivative products, including the Suter privacy mining program, xSuter auction, Suter NFT, and others.

Huang Lin is the platform’s founder.
