Abstract: An apparatus, system, and method are disclosed for data recording and retrieval on one or more blockchains using an operational token. One apparatus includes a processor and a memory storing code executable by the processor, wherein the processor receives a first request that contains input data and tag data. The processor stores the input data to a shared ledger of a first blockchain based on the tag data and generates an operation token corresponding to the first request. Here, the operation token associated the input data with a user and an operation identified corresponding to the stored input data. Additionally, the processor transmits the operation token to a user.
