Claim 11:
12. A method for providing a further timestamp transaction, comprising:
receiving a hash of a dataset via an interface;
determining, via a computation unit, a time by querying a time server;
determining, via the computation unit, 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;
determining the further timestamp transaction via the computation unit, the further timestamp transaction including at least the hash of the dataset and the further verification time; and
providing the further timestamp transaction via the interface.
