Embodiments are described for a digital currency hub (DCH) comprising a memory and a processor. The processor is configured to receive a confirmation of a transaction. The confirmation indicates a first amount in a first cryptocurrency (the “transaction amount”) and a second amount in a second cryptocurrency (the “network fee”). The processor is further configured to adjust a first position corresponding to the first cryptocurrency based on the first amount and adjust a second position corresponding to the second cryptocurrency based on the second amount. The adjustments can be pro-rata. The processor is further configured to calculate gains or losses based on the adjustments of the positions. In some embodiments, the DCH enables the ERP system to handle cryptocurrencies according to the rules of various accounting principles in parallel, because the ERP system is not compatible or capable of handling digital transactions with respect to accounting regulations directly.

Data Processing Apparatus for Crypto Currency Market Tracking

Examples predict changes in risk scores in cryptocurrency transactions between potential transacting parties. The system identifies a tentative transaction between the sender and receiver on a cryptocurrency blockchain. The system builds a receiver transaction tree based on cryptocurrency transactions already recorded in the blockchain. The system also similarly builds a sender transaction tree. The system calculates a current risk score of the sender party based on the second transaction tree. The system builds a third transaction tree by adding the first transaction tree into the second transaction tree, thereby simulating the sender party as having transacted with the receiver party. The system then calculates a predicted risk score of the sender party based on the third transaction tree and transmits one or more of the predicted risk score and a change in risk score to the sender party.

A method of using cryptocurrency to transact fiat currency purchases using conventional POS apparatus includes funding by a user of a cryptocurrency account that requires withdrawal transactions to be signed by both the user and a payment platform. Upon purchase initiation, a platform-issued authorization number is entered into a merchant's POS apparatus and transmitted to the platform. Upon verification of sufficient cryptocurrency, the platform transmits payment information to the user, and upon approval thereof by the user, the user transmits a user-signed cryptocurrency transaction to the platform, and the platform remits fiat currency to the merchant. As purchases continue during an aggregation period, each user-signed transaction is sufficient to fund the aggregated purchases. Upon termination of the aggregation period, the most recent user-signed transaction is executed to withdraw cryptocurrency from the user's account. The user can display the authorization number on a mobile device for scanning by the POS apparatus.

A physical cryptocurrency may comprise a physical medium and an attached processor.
