MasterCard to use blockchain

Method and System For Instantaneous Payment Using Recorded Guarantees - this is the name of the patent recently filed by MasterCard. It describes a system similar to blockchain and one of its most attractive aspects — distributed ledger:

“...the payment guarantee data stored in the third data element included in the received transaction message includes at least a blockchain network identifier and (i) a public key or (ii) a destination address, the record of payment guarantee is a blockchain transaction for payment of the transaction amount stored in the second data element included in the received transaction message to (i) the destination address or (ii) a destination address associated with the public key, and the computing system is a node in a blockchain network corresponding to the blockchain network identifier.”

Although the CEO of MasterCard, as one might remember, does not support Bitcoin at all and called it “junk”, this does not mean he can’t implement blockchain in MasterCard payments now.

The USPTO website sometimes can serve as a keyhole through which the cryptocurrency community can peek at the future blockchain-related plans of major corporations.
