Method and system for blockchain transaction confirmation for small merchants

Abstract

A method for facilitating payment transactions for offline merchants through a third party service provider includes: receiving, by processing server, a confirmation message for a payment transaction from a computing device including a merchant identifier, consumer identifier, and transaction amount; generating, by the processing server, a notification message including the merchant identifier, consumer identifier, and transaction amount; encrypting, by the processing server, the notification message using a public key of a first cryptographic key pair; transmitting, by the processing server, the encrypted notification message to the computing device; receiving, by an encryption device, the encrypted notification message from the computing device; decrypting, by the encryption device, the encrypted notification message using a private key of the first cryptographic key pair; and displaying, by a display interfaced with the encryption device, a confirmation message including the consumer identifier included in the decrypted notification message.
