Patent attributes
A system includes processors and instructions that, when executed by the one or more processors, cause the system to perform operations of receiving a blockchain check request from a first network participant, generating a paper blockchain check including a QR code, issuing the paper blockchain check to the first network participant, obtaining an image of the issued paper blockchain check, determining whether the bank account associated with the first network participant has access to a sufficient amount of funds, associating the designated amount of funds and the identifier of an intended recipient with the QR code, locking funds in the first network participant's bank account, generating, upon the intended recipient being validated with the blockchain, a digital blockchain check based on details associated with the scanned QR code, and disabling the paper blockchain check after the conversion of the paper blockchain check into the digital BC check.
