Abstract
A method is disclosed for distribution of resources to network nodes in a decentralized data network. In at least one embodiment of the method keywords, which are allocated to digital resources, are mapped onto digital bit sequences. These bit sequences are modified, with the subsequent bits after a predetermined bit position, preferably being replaced by random bits. A mapping onto bit sequences is then undertaken with these modified bit sequences, with each network node being responsible for a specific range of values of indices. The resource will then be allocated the index which is produced by the mapping. The mapping in this case can be selected so that a wildcard search according to keywords is guaranteed. The outstanding feature of the method is that the resources are distributed evenly in the decentralized network and at the same time a fast wildcard search according to truncated keywords is made possible.
