Claim 14:
15. A computer-implemented method, comprising:
receiving, using at least one processor, a request from a first computing system to modify a local replica of reference data, the local replica being maintained at the first computing system, the reference data being maintained at a second computing system, and the request comprising temporal data associated with the requested modification;
using the at least one processor, determining a request time associated with the request based on the temporal data, approving the requested modification to the local replica of the reference data based on a notarization criterion maintained within an element of a distributed ledger and based on the request time, and perform operations that record notarization data characterizing the approved modification within an additional element of the distributed ledger; and
transmitting, using the at least one processor, the notarization data to the first computing system, the notarization data causing an application program executed by the first computing system to modify the local replica in accordance with the notarization data.
