Abstract:
An apparatus maintains a segregated database in a multiple distributed ledger system. The apparatus includes a storage device that stores software instructions for controlling a processor that when executed by the processor configure the processor to: create distributed ledgers, each created distributed ledger being associated with a respective individual profile; maintain a segregated database apart from the distributed ledgers including, for each individual profile, profile balance data; and process a data exchange between exchanging profiles. To process the data exchange, the processor is configured to receive data exchange data regarding parameters of the data exchange; approve the data exchange based on a check of the data exchange data against profile balance data in the database; access the distributed ledgers associated with the exchanging profiles; and cause a distributed ledger data exchange corresponding to the data exchange to be added to the accessed distributed ledgers when the data exchange is approved.
