Blockchain based bank checking network with paper checking enhancements

A system comprising:

• one or more processors;
• and
• one or more memory devices storing instructions that, when executed by the one or more processors, cause the system to perform operations of:
• receiving a BC check request from a first network participant, the BC check request indicating at least:
• and a bank account associated with the first network participant;
• generating a paper BC check including a unique QR code, a blank field wherein the first network participant may write-in a designated amount of funds, and a blank field wherein the first network participant may write-in an identifier of an intended recipient of the designated amount of funds;
• wherein the QR code is associated with one or more of:
• a check number, a link to a downloadable digital wallet application, an identifier associated with the first network participant, an address associated with the first network participant, a wallet ID associated with the first network participant, a bank account detail associated with the first network participant;
• wherein a bank account detail includes one or more of:
• an account number, an international bank account number, a swift code, and a routing number;
• issuing the paper BC check to the first network participant;
• obtaining, after the first network participant writes in the designated amount of funds and the identifier of an intended recipient, an image of the issued paper BC check, wherein the identifier of the intended recipient is associated with one or more of a wallet ID, an address, an account number, an international bank account number, a swift code, and a routing number;
• determining whether the bank account associated with the first network participant has access to a sufficient amount of funds to ensure the intended recipient's ability to redeem the paper BC check;
• causing, in response to determining that the sufficient amount of funds exists, the designated amount of funds and the identifier of the intended recipient to become associated with the QR code;
• locking, upon associating the designated amount of funds with the QR code of the paper BC check, an amount of funds in the first network participant's bank account, the amount of funds locked being based upon the designated amount of funds;
• wherein locking imposes usability restrictions on one or more of digital currency and fiat currency in the first network participant's bank account corresponding to the amount of funds;
• notifying the first network participant that the paper BC check is transferrable to the intended network participant;
• notifying a blockchain that that the paper BC check has been one or more of generated, written, and issued, and optionally notifying the blockchain of one or more of the designated amount of funds and the identifier of the intended recipient;
• scanning, by a device associated with the intended recipient and after the first network participant has presented the intended recipient with the paper BC check, the QR code from the paper BC check;
• obtaining details associated with QR code based on the scanning of the paper BC check;
• generating, upon the intended recipient being validated with the blockchain, a digital BC check based on the details associated with the scanned QR code;
• disabling the paper BC check after the conversion of the paper BC check into the digital BC check.
