Introduced here are computer programs and associated computer-implemented techniques for purchasing, selling, and/or transferring cryptocurrency to be disbursed as a reward for using a specialized payment card. The technology allows cardholders to receive cryptocurrency for completing transactions with specialized payment cards without requiring the card-issuing financial institution directly issue the cryptocurrency.

The usage of money has been always abused for financial crime. The invention of cryptocurrency on Blockchain did not change that since the ownership essentially remained anonymous. The present invention deals with the programmatic parameterization of cryptocurrency Smart Contracts to include the binding between the user's cryptocurrency transaction and user's Identity, thus creating “permissioned” crypto-token transfer. Such binding has advantageous properties as being resilient to any form of financial crime, preventing cryptocurrency theft, and precluding “bad actors” from using this cryptocurrency. The system for Identity-Bound Cryptocurrency Transfer (IBCT) will include IBCT Blockchain Smart Contract, IBCT Blockchain Oracle Smart Contract, and off-chain Identification-as-a-Service for the IBCT owner using dedicated CryptoWallet for executing IBCT Smart Contract. The Financial crime-preventive usage of cryptocurrency is achieved through user-opted, while pseudonymous, binding of the user's Blockchain public address with the user's identity. This Financial crime-preventive usage of cryptocurrency is facilitated via a specialized crypto wallet.

Systems and methods for facilitating a transaction between a first entity and a second entity using a digital currency are described. In some aspects, a computing node participates in a private distributed ledger for a financial institution and stores one or more transaction blocks representing transactions in a digital currency. The digital currency is issued by the financial institution and is fixed with respect to a fiat currency. The computing node is configured to receive a transaction for transferring an amount of digital currency from a first entity to a second entity, generate a new transaction block representing the transaction, transmit the new transaction block to other computing nodes participating in the private distributed ledger, receive an indication of validity of the new transaction block, and insert the new transaction block into the private distributed ledger.

A non-transitory computer readable storage medium has instructions executed by a processor to maintain a digital wallet with digital identities. Each digital identity has identity attributes different than identity attributes associated with a real individual utilizing the digital identity, an associated attribute for compartmentalized network activity, a digital identity key pair, and a designated block chain. Interactions between the digital identities of the digital wallet and a digital identity services platform are supported.

The present invention relates to a driving method of a block chain-based health data management system. When personal health data such as health examination or prescription data and the like is uploaded, a genome portal: stores the personal health data as metadata together with genetic information; provides the personal health data so that a demand agency requiring the personal health data can use Zerocoin to purchase or read the personal health data through the genome portal; provides rewards in the form of mileage to individuals who share the data in the genome portal; ranks the individuals by the number of times the individuals have shared the data; automatically presents various personalized health solutions in the portal through AI according to the shared data; provides a rapidly growing personal genome prediction/diagnosis service through a portal system by using a blockchain-based MS decentralized identity (DID) in order to enhance the security of the email addresses and IDs of users; and ascribes value to personal health big data, such as genome data, medical diagnosis information, or social data, and so as to reduce the costs of personal genetic testing and diagnosis.

The Computationally Efficient Transfer Processing, Auditing, and Search Apparatuses, Methods and Systems (“SOCOACT”) transforms smart contract request, crypto currency deposit request, crypto collateral deposit request, crypto currency transfer request, crypto collateral transfer request inputs via SOCOACT components into transaction confirmation outputs. Also, SOCOACT transforms transaction record inputs via SOCOACT components into matrix and list tuple outputs for computationally efficient auditing. A blockchain transaction data auditing apparatus comprises a blockchain recordation component, a matrix Conversion component, and a bloom filter component. The blockchain recordation component receives a plurality of transaction records for each of a plurality of transactions, each transaction record comprising a source address, a destination address, a transaction amount and a timestamp of a transaction; the source address comprising a source wallet address corresponding to a source digital wallet, and the destination address comprising a destination wallet address corresponding to a destination virtual currency wallet; verifies that the transaction amount is available in the source virtual currency wallet; and when the transaction amount is available, cryptographically records the transaction in a blockchain comprising a plurality of hashes of transaction records. The Bloom Filter component receives the source address and the destination address, hashes the source address using a Bloom Filter to generate a source wallet address, and hashes the destination address using the Bloom Filter to generate a destination wallet address. The Matrix Conversion component adds the source wallet address as a first row and a column entry to a stored distance matrix representing the plurality of transactions, adds the destination wallet address as a second row and column entry to the stored distance matrix representing the plurality of transactions, adds the transaction amount and the timestamp as an entry to the row corresponding to the source wallet address and the column corresponding to the destination wallet address; and generate a list representation of the matrix, where each entry in the list comprises a tuple having the source wallet address, the destination wallet address, the transaction amount and the timestamp.

The present disclosure generally relates to the field of digital currency, more particularly, cryptocurrency and secure payment systems using Public-key cryptography. The new cryptocurrency system utilizes digitally locked coins that can be owned and exchanged anonymously without the need for any owner account. Coin owners exchange coins by sending the digital keys of the coins, and recipients use the received digital keys to change the digital locks of the received coins. The digitally locked coins are tracked in a public book that is maintained centrally or distributively by one or more bookkeepers. The new cryptocurrency system is efficient and provides fast, anonymous, and secure transactions.
