Abstract:
The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that manage cryptographically secure exchanges of data using a permissioned distributed ledger. For example, an apparatus obtains parameter values characterizing an exchange of data and transmits the parameter values to a first computing system, which executed instructions included within a distributed ledger. The executed additional instructions cause the first computing system to access rules data recorded onto the distributed ledger and establish a consistency between the parameter values and at least a portion of the accessed rules data. The apparatus receives, from the first computing system, confirmation data indicative of the established consistency, and based on the confirmation data, transmit a request to execute the data exchange in accordance with at least the portion of the parameter values to a second computing system.
