Systems and methods are provided for sending a request to register a data offer from a data owner to participate in a distributed ledger, the request including information associated with the data offer and a privacy budget for the data offer, and wherein the information associated with the data offer and the privacy budget is stored in the distributed ledger and the data offer is accessible by third parties to the data owner. The systems and method further providing for receiving a request, associated with a third party computer, to access data associated with the data offer, processing a data request associated with the request to access data, based on determining that there is sufficient privacy budget to allow access to the data associated with the request to access data, to produce result data, anonymizing the result data, and updating the distributed ledger.
