Kin is a decentralized cryptocurrency that was created in 2017 by Kik Inc.

Kin was initially launched on the Ethereum blockchain. In 2020, Kin migrated to the Solana blockchain in order to achieve lower transaction fees and greater scalability.

Notably, Kin has zero inflation. The Kin supply is fully distributed and no additional Kin tokens will enter circulation.

In 2020, Kik Inc agreed to a mutual settlement with the United States SEC in which Kin was not required to be registered as a security, making it one of the few cryptocurrencies with such regulatory clarity.

Hifi (formerly Mainframe) is a Lending Protocol that allows anyone to borrow against their crypto. Hifi uses a bond-like instrument, representing an on-chain obligation that settles on a specific future date. Buying and selling the tokenized debt enables fixed-rate, fixed term lending and borrowing — something much needed in decentralized finance today. It is anticipated that a ticker symbol change will occur alongside future iterations on the Hifi Lending Protocol.

Mainframe Token (MFT) is the native utility token that is used for:

Governance votes

Staking to ensure the safety of the protocol

Rewarding contributors to the ecosystem

What can you do with the Hifi Lending Protocol:

Borrow:  Lock collateral in a vault to mint fixed-rate, fixed-term debt tokens.  These debt tokens can be swapped for instant liquidity allowing users to leverage long, yield farm, or pursue other strategic trades without selling their collateral tokens.

Lend:  Buy fixed-rate, fixed-term debt tokens for a discount.  When the term expires they can be redeemed for face value, earning lenders a predictable return on their investment.

Provide Liquidity:  Earn trading fees by providing liquidity between debt tokens and stablecoins on an Automated Market Maker (AMM).

CyberVein's big-data solution is based on the PISR (private, interlink, secure, robust) distributed database, database operations are stored on CyberVein blockchain network which runs on a Proof-of-Contribution (PoC) consensus mechanism. The solution is focusing on enterprise-level "blockchain + big-data" customized services.

CVT is the native utility token that is used for:

Storage payment: The data owner pays the corresponding storage fee based on the file size and bandwidth consumed in such a process.

Computing power payment: Payments from user to owner for usage, and remuneration for software developers is going to be exclusively conducted in CVT.

Data exchange: On CyberVein's federated learning platform, the data acquirer trades the data at a price contracted between the two parties for distributed modeling applications.

CROSS NFT issuance payment: Dapp businesses are obligated to pay for Storage and Data Exchange in light of network resources occupied, and may set up CyberVein token as a means of payment to issue NFT or conduct business in accordance to their desired business model.

CyberVein tools include:

PISR Consortium database, creates better data management: through safe and reliable virtual machine operation and maintenance of user data, data is efficiently aggregated for upstream data, and data traceability and tracking are realized to ensure the reliability of data sources and outputs, and achieve cross-level, cross-departmental data sharing to improve the timeliness, diversity, stock and density of data to realize the commercial value of data, and truly solve the problems in data flow.

DAG storage chain, creates safer data storage, with better efficiency, no block confirmation, low transaction fees, and also eliminates miner, supports asynchronous verification and parallel processing of each node, the more nodes, the faster the speed, the stronger the scalability, which leads to better scalability. The database backup on DAG storage chain provides an extra layer of security for businesses.

Cytrix, allows GPU to be shared. Nodes can contribute part of their GPU to the network, in return for compensation through the Proof of Contribution mechanism. The contributed GPU can aid enterprises or individuals in data modeling with federated learning.

Federated Learning Platform, enables data to be monetized. Federated Learning is a distributed machine learning workflow. The datasets are first trained locally, and the data of all parties is kept locally, without revealing privacy or violating regulations.  Individual terminals return trained models to the server to create a shared model. Effectively protect data privacy and security, solve the problem of information silo, and thus realize the value of data. The platform will also provide algorithms to support data modeling operations by enterprises and individuals.

The Suterusu Protocol is a second-layer private payment infrastructure for smart contract platforms. The Suterusu Protocol uses the original and most advanced ZK-ConSnark algorithm that does not require a trusted setup. The algorithm’s proof size is significantly reduced and the proof generation and verification efficiency are greatly improved compared with similar solutions. Since no trusted setup is required, it is safe and transparent. The technical paper has been accepted by Eurocrypt 2021(https://eurocrypt.iacr.org/2021/acceptedpapers.php, https://eprint.iacr.org/2021/540). The Suterusu Protocol has been deployed on Ethereum, Binance Smart Chain, Heco, SmartBCH (BCH sidechain), Theta, etc. We plan to deploy Suterusu protocol on the following smart contract platforms including Near, Solana, Avalanche, Moonbeam, Plasma, Matic, etc. It is also the first privacy project funded by the official Cypherpunk Guild Fund of Near. We are also applying for the Solana and Polkadot ecosystem grant. The Suterusu Protocol intends to build a private payment infrastructure for any cryptocurrency. The Suterusu project has received investment from well-known institutions such as Dialectic (a fund founded by the former Polychain partner Ryan Zurr), Fundamental Labs, FBG, Continue Capital, DeFi Alliance, and other well-known institutions.
