## What Is Public Mint (MINT)?

Public Mint’s primary goal is to bridge the gap between crypto and [fiat](https://coinmarketcap.com/alexandria/glossary/fiat) currencies. It offers a fully collateralized, regulated and FDIC-insured platform for synthetic fiat currencies.

Public Mint also offers a fiat-native blockchain, APIs and an embeddable web widget. It allows developers to build fiat-enabled applications that accept credit cards, ACH, wire transfers and more. Public Mint launched in 2020.


### Who Are the Founders of Public Mint?

The founders of Public Mint are Halsey Minor, founder of CNET and Uphold and co-founder at Salesforce, and Jorge Pereira, former CTO at Uphold and current CTO at Public Mint. The company’s CEO is Paulo Rodrigues, former Head of a Swift bureau and CEO at a blockchain R&D center


#### What Makes Public Mint Unique?

Public Mint allows users to transact with tokens pegged to fiat currencies. The platform offers a fiat-native blockchain where users can deposit fiat currencies to tokenize them for later use on the Public Mint network. It combines the price stability of fiat currencies and blockchain’s 24/7 accessibility, global reach and efficiency.

The Public Mint blockchain connects two distinct off-chain and on-chain domains. Users can operate each of the domains with different scopes, requirements and limitations. 

At the network level, Public Mint combines a traditional client-server model with an Ethereum-compatible blockchain. The system connects with custodial partners and KYC providers to ensure compliance with beneficial regulations. The platform makes sure that the minting and burning of on-chain tokenized fiat assets corresponds to the respective changes in funds held in the custodial layer.

The Public Mint ecosystem consists of three layers. The multi-custodial layer is represented by Custodial Partners — licensed financial institutions that hold custody over fiat funds at a 1:1 ratio to the tokenized assets.

The blockchain layer, based on Hyperledger Besu, is an enterprise-grade Ethereum ([ETH](https://coinmarketcap.com/currencies/ethereum/)) client.  However, the Public Mint platform is independent of Ethereum, as it controls its own transactional logic and the deployment and maintenance of blockchain infrastructure.

The Smart Services layer comprises the smart contracts that add functionality on top of the blockchain foundation. Public Mint handles state changes similarly to the Ethereum Virtual Machine ([EVM](https://coinmarketcap.com/alexandria/glossary/ethereum-virtual-machine-evm)). Smart contracts can be written in any Ethereum-compatible language.

Public Mint also has a liquidity rewards program, allowing liquidity providers to earn MINT tokens.

KardiaChain is a blockchain platform that aims to be fully interoperable and "non-invasive," meaning that blockchains can connect to the network without needing to make technical modifications to their own protocols. KardiaChain uses a dual-node structure to facilitate the connection between its own ledger and other blockchains, sharding for scalability and smart contracts for developers.

The platform relies on a native token, KAI, which is used for staking, transaction fees, participating in services and deploying smart contracts.

KardiaChain was first announced in October 2018, and its mainnet went live in December 2020.

xDai is a cryptocurrency that is pegged to the US dollar. The xDai chain is a stable payment blockchain that is designed for fast and inexpensive transactions. STAKE is secured by proof-of-stake consensus. xDai was founded on Oct. 1, 2018.

STAKE is a multi-chain staking token that is designed to secure the payment layer. Staking allows validators and delegators to provide transaction consensus and receive staking incentives for block production. It is only required for consensus providers, not everyday on-chain transactions.

xDai was created by the POA Network, an open-source public side-chain of Ethereum founded in April 2017. It offers a framework for smart contracts which provides developers with an easy and effective way to code on Ethereum, while also leveraging the POA Network capabilities.

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.
