Research and development progress

1.1 Suter Stats’ data display has been optimized.

1.2 We did a lot of research to reexamine Suter's payment compliance issue, and discussed how to design an architecture that operates well on BSC, so as to ensure compliance and privacy protection to match your needs.

We have designed three alternative architectures from light to heavy, and we will explore the possibility of cooperation with BSC.

Step 2

2.1

Connect your wallet. Since Suter Shield V3 privacy-protected transaction feature is only available on BNB Chain, please switch your wallet to BNB Chain. You can choose your frequently used wallets to connect.

2.2

Select “Sign Up” to register a Suter account. Since the V3 account is upgraded to a single account that supports all crypto transactions, it is not compatible with the V2 version account.

Step 3

3.1

You can choose a random private key generator provided by Suterusu or enter a private key of your choice.

3.2

Enter your private key into the dialog box and register. After successful registration, a file with your private key will be automatically downloaded and stored locally.

Suterusu will not keep or know your private key file during this process.

Step 4

4.1

Click on “Deposit” to deposit the assets you need to privately transfer.

4.2

The new Suter Shield supports privacy-protected transactions of multiple cryptos from one account. You can select the crypto you want to transfer from the drop-down list. The current page is only a demo; we will add more crypto options when it goes live.

4.3

Select the token amount you would like to deposit to the Suter Shield protocol. Please note that 1 Unit BNB = 0.01BNB in this case due to the difference in minimum counting units.

Step 5

Click “My S-Token”, where you can add all the assets that you have deposited to the Suter Shield protocol.

Step 6

Click “Transfer” to select the crypto, amount, and address for the privacy-protected transaction you want to make.

We support any wallet address or Suter Shield account address you wish to transfer tokens from, but please do not transfer tokens directly to exchange deposit addresses as they do not recognize assets transferred by smart contracts.

Congratulations, you have successfully tested the privacy-protected transaction feature developed by the Suterusu protocol.

Events & News

2.1 During the past two weeks of Suter Shield V3 beta testing, we have received a lot of feedback. We decided to select and share a few reviews to the community in the hope that they may help in your circumstances.

Q1: Recent Operation - I did a single-digit SBNB transfer from one Suter V3 address to another Suter V3 address.

E.g. I transfer 5 SBNB.

It shows up as "Transfer O SBNB" and not "Transfer 5 SBNB".

Is this by design or an error?

A：Please confirm you have actually transferred 5 BNB to the other address successfully. It's very likely that the transfer is not successful or the transferred amount is indeed 0.

Q2: Recent Operation - - it shows date but would be good if it also shows the time stamp.

A: Sure, we will take that into account for our update.

Q3: Sir, even though I am on the BSC network, I received an error that the transaction was not performed because I am on the ETH Network, but I didn't get a screenshot!

A: Please take a screenshot next time so that our engineer could actually confirm this is indeed a problem with our product. We will definitely check it out if this is indeed an issue.

Q4: 1 Unit BNB = 0.01 BNB It is little bit confusing to me also. At first it's looks like you have 86 BNB. But actually you have 0.86 BNB. Is it possible to hide this underlying algorithm from user? Can you just use multiply/divide so that user will only see actual BNB?

A: This is an interesting suggestion. We will definitely take it into account for our next update.

Q5: To which address can I transfer SBNB?

A: Your Suter account.

Q6: Where can I see incoming S-Token transfers?

A: You will be able to check the records of transfer transactions in our updates (coming soon!)

Q7: If I refresh the page while having my wallet connected and logged in - my account disconnected and logged out. So if I do page refresh, I have to connect wallet and do login again. Why?

A: This is indeed not a very desirable feature. We will try to let the users decide when they wish to disconnect the Suter account and log out in our future update.

2.2 With the rapid development of web3 ecosystem, we noticed that most projects have migrated their DAO voting to Snapshot.

In order to implement the idea of decentralized governance, Suterusu is also currently moving Suter Dao to https://snapshot.org/#/suterians.eth, and we are eagerly awaiting proposals from the community. 

2.3 We are fully aware that the community is concerned about the release date of Suterusu's “Space Odyssey” game.

It took our team a lot of effort and energy to plan and produce a complete game. However, considering the complicated market trend and the failure of the economic model that many excellent blockchain gaming projects can not avoid, we are still cautiously exploring and testing the economic model of Space Odyssey again and again.

After several major revisions, coupled with the team's tight resources for development, the current delay has indeed exceeded the expectations of the community and the team itself, but an excess of caution does no harm.

As for the latest development of the game, we will inform you as soon as possible.

Key management has always been one of our major focuses since the safety of users’ asset rests almost entirely on the success of the underlying key management scheme. Suter’s current key management scheme is undoubtedly the most secure and decentralized one compared with our competitor products such as Aztec and Tornado.cash.

We have been constantly working on finding the optimal balance between usability and security of our key management scheme.

Recently, we have designed an even better key management scheme that could potentially improve its usability significantly. We are still working on improving the system design and are about to move forward to the production phase soon. Stay tuned.

As a privacy protection infrastructure for Web 3.0, Suterusu aims to build a modular, dynamic and versatile privacy-protection ecosystem by integrating state-of-the-art cryptographic technology.

In addition to our existing flagship product, Suter Shield, we plan to launch new products to better protect individual privacy in the Web3 world. Our first new product will be dedicated to guaranteeing the fairness of the NFT auction. Built on Suterusu's advanced ZK-Consnark protocol, the new NFT auction scheme will be fair and resistant to various well-known attacks such as front-running. The attackers will not be able to snap the rarest items at the expense of regular users.

Project statistics

Abstract. Web 3.0 enables individual internet users to become the owner of their content, data, and assets. However, without a privacy- protection infrastructure that can protect the users’ content, data, or digital assets from unwanted attention, it would be impossible for the users to have full control of their digital life.

Suterusu will play a central role in protecting the users’ privacy in the world of Web 3.0. Our current product Suter Shield, as a private payment infrastructure for smart contract platforms, has achieved tremendous success in terms of both user accounts and processed transaction volume.

This white paper will show how we will build on Suterusu’s existing work to establish a fully-fledged privacy-protection infrastructure that is accessible to every single Web 3.0 user.

1 Introduction

We live in a swiftly changing world. The emerging thesis of the internet economy that could potentially change every aspect of human life is Web 3.0, in which each internet user will have full ownership of their content, data, and assets. Suterusu, previously a leading private payment infrastructure for smart contract platforms, will become a privacy-protection infrastructure for Web 3.0 in this new age. Our leading product Suter Shield has attracted over 15 thousand users and processed over 200 million USD worth of transactions as of today, which will continue to protect the users’ transaction privacy.

We will continue improving the performance of ZK-ConSNARK technology, and adopt aggregated proof to reduce the transaction cost. Based on our existing zero-knowledge proof technology, we will design and implement an on-chain auction scheme that guarantees the fairness of on-chain auction and thus bring Web 3.0 experience to every internet user.

Non-fungible token (NFT) has detonated the explosion of gamefi summer of this year. It has been recognized by the Messari report as a foundation for Web 3.0, and could potentially become a universal building block for metaverse, decentralized identity, and decentralized social networks.

We will extend Suter Shield to protect the payment privacy of non-fungible tokens. This not only means Suterusu will provide privacy protection service for the essential building block of Web 3.0, but is also a testament to Suterusu’s resolve to become the dominant player in the Web 3.0 world.

2 Cost-efficient Suter Shield

Suter Shield has achieved great success, with over 15 thousand users and 200 million USD worth of transactions processed. It has also demonstrated its flexibility and composability since its launch. We have developed various derivative products based on Suter Shield such as the Suter privacy mining program, xSuter auction, Suter NFT, etc. Despite our novel ZK-ConSNARK technology, there remains room for us to further improve the performance of Suter Shield. Our next step will be adopting an aggregate zero-knowledge proof to reduce the proof size and thus related gas cost. The gas saving rate could range from 5x to 100x depending on the level of aggregation. Suter Shield will be a product that is affordable to every single Web 3.0 user.

3 Fair on-chain auction

The story of blockchain is that it requires no trusted third party and hence guarantees the transparency and fairness of online transactions. But hold your horses, due to the transparent nature of the blockchain-based solutions, the price manipulation, and front-running by a technically sophisticated bidder [1]is indeed a lot easier than in the traditional setting. As a matter of fact, it has been indicated in a well-known report from Paradigm [1], the ability to prevent front-running attacks and guarantee the fairness of the auction is considered one of the most important feature of a fair NFT auction.

Suterusu project will build a fair auction scheme based on Suter Shield and public-key encryption. The bidding price will be protected by encryption and the bidders’ committed tokens will be locked during the entire auction period. The contract will automatically enable the exchange of auctioned goods such as NFT and the unlocked committed token of the auction winner. It will guarantee the following properties:

1). No competitive conditions: Since all the bidding prices will be encrypted and kept secret from the other bidders, the competitive conditions mentioned in [1] will be eliminated. It would be meaningless now for the buyers to race to get their bidding offer to be mined before their competitors since they don’t even know their competitors bidding price. This would significantly improve the fairness of the auction, and hence provide a better price discovery mechanism for the auctioned goods.

2). Not restricted by time zone: Since before the end of the auction, all the bidding price is encrypted and no bidders have any advantage over their competitors regardless of their bidding orders, one could join the auction at any time before the auction ends as they wish. We could set the length of the auction to be more than 24 hours so that any interested bidders from all time zones can join the auction at their most convenient time.

3). Resistance to Sybil attacks: As the bidders are required to commit a certain amount of Suter tokens before joining the auction, this alone will protect the auction against the Sybil attacks due to the economic and computational cost of registering and depositing operation.

1. No trust: our underlying encryption scheme be decentralized and the zero- knowledge proof scheme is trustless.

4 Anonymous vault for non-fungible token (NFT) The existing Suter Shield scheme aims to sever the connection between the layer- 1 addresses that deposit tokens to the Suter network and those that withdraw from the Suter network. The Suter transfer functionality further guarantees a network of Suter accounts obfuscates the flow of tokens in the Suter pool. We also apply a homomorphic encryption scheme to hide the transactional amount.

Since by definition, each non-fungible token is unique. Therefore, it is impossible to sever the link of incoming and outgoing layer-1 addresses holding the NFT. However, once an NFT is deposited into the Suter contract, we can apply the Suter transfer contract to anonymize the holders of non-fungible tokens. This essentially will create an anonymous vault for NFT. Our anonymous vault scheme will guarantee the holder anonymity of the NFT before it is withdrawn from our network, and thus create a dark period of NFT’s lifetime.

5 Conclusion This white paper summarizes how Suterusu intends to become essential privacy- protection infrastructure for Web 3.0. We explain the three main products that we intend to deliver in the next few months: 1. cost-efficient Suter Shield, 2. fair on-chain auction, and 3. anonymous vault for non-fungible tokens.
