Abstract
A system for offline transaction processing has a payment terminal capturing payment credentials and a payment amount as a transaction data set. A first blockchain server has a first copy of a transaction ledger to which the transaction data set is committed as a ledger entry in response to a validation against one or more rules stored in an offline database. A second blockchain server has a second copy of the transaction ledger, and is in sporadic communication with the first blockchain server over a temporary data transfer link. The transaction data set previously committed to the first copy of the transaction ledger is propagated to the second copy of the transaction ledger over the temporary data transfer link. A payment gateway retrieves the transaction data set in the second copy of the transaction ledger and translates the same to a settlement request transmitted to the remote payment processor.
