A server receives loyalty points disbursement (LPD) parameters including at least an initial earn rate, a loyalty points budget, and a disbursement period. The server receives an LPD request corresponding to a transaction performed by a user. The server updates the initial earn rate based on at least one of real-time transaction data, predictive transaction data, real-time market disbursement data, and predictive market disbursement data. The server disburses a first set of loyalty points, from the loyalty points budget, to the user based on at least the updated earn rate and a transaction amount of the first transaction.

Abstract: A method for minimizing inter-bank settlement through incremental updates stored via blockchains includes storing three blockchains: a balance blockchain updated periodically that includes an available balance for a plurality of blockchain wallets, a credit blockchain that includes credits made to a blockchain wallet, and a debit blockchain that includes payments made from the blockchain wallet. Holds are placed on related transaction accounts to enable the blockchain wallets to utilize payments made thereto without the need for a transaction account, where the holds are only updated when necessary based on periodic updates to the balance blockchain, thus minimizing settlements performed by the issuing institutions, thus reducing inter-bank settlements and enabling payees to receive payments from a transaction account without their own.
