Claim 22:
23. A transaction creation system for providing a further timestamp transaction, the transaction creation system comprising:
an interface, the interface configured to
receive a hash of a dataset, and
provide the further timestamp transaction; and

a computation unit, the computation unit configured to
determine a time by querying a time server,
determine a further verification time based on the time, the further verification time being determined such that the further timestamp transaction can be inserted into a number of data blocks of a distributed ledger and the number of data blocks can be created before a current time is later in time than the further verification time, and the further verification time being later than the time, and
determine the further timestamp transaction, the further timestamp transaction including at least the hash of the dataset and the further verification time.
