Abstract

A method for generating a cryptographic promissory note for posting to a blockchain includes: receiving an authorization request for a payment transaction, the authorization request being a transaction message formatted based on one or more standards that includes a plurality of data elements including a first data element configured to store a blockchain address and a second data element configured to store a transaction amount; generating a promissory note including the transaction amount; digitally signing the generated promissory note with a private key; encrypting the signed promissory note with a symmetric key; wrapping the symmetric key with a public key corresponding to the private key and a public key associated with an acquirer involved in the payment transaction; and electronically transmitting a blockchain transaction to a blockchain network that includes the encrypted promissory note, each symmetric key, and the blockchain address.
