Claim 0:
1. An apparatus, comprising:
a memory storing instructions;
a communications interface; and
at least one processor coupled to the communications interface and the memory, the at least one processor being configured to execute the instructions to:
receive, from a first computing system via the communications interface, a first request 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 first request comprising first temporal data associated with the first requested modification;
determine a first request time associated with the first request based on the first temporal data, approve the first requested modification to the local replica based on a notarization criterion maintained within an element of a distributed ledger and based on the first request time, and perform operations that record notarization data characterizing the approved modification within an additional element of the distributed ledger; and
transmit the notarization data to the first computing system via the communications interface, the notarization data causing an application program executed by the first computing system to modify the local replica in accordance with the notarization data.
