Abstract
A proof-of-payment system may receive a payment confirmation including a transaction amount and a merchant identifier. The system may select a record from a registration repository by matching the merchant identifier to the record. The record may have a public key associated with the merchant identifier via a registration process, for example. The system may also generate a proof-of-payment payload comprising an identifier and a payment amount, and encrypt the proof-of-payment payload using the public key. The system may write the encrypted proof-of-payment payload to a blockchain maintained on a first blockchain node.
