A system and method for payment notification using blockchain. The system and method relate to real-time monitoring and updating of a list of accounts that have not satisfied a minimum payment amount due. The real-time monitoring and updating of the list occurs through the use of a blockchain monitoring payment information by a user to the account. The blockchain is continually updated every time a payment is made. A notification system receives each update and is aware, in real-time, whether a user has satisfied a minimum payment amount due and thus whether an account is current or in need of a collections notification.
