Abstract: Disclosed is a resource management system that maintains records relating to transactions associated with resources, wherein the system is implemented as a distributed ledger arrangement including data processing nodes that are coupled via a data communication network. The records are maintained in corresponding chains, wherein each chain includes a temporally defined sequence of verified entries and each entry defines corresponding transactions. When new entry is to be made to a given chain, information concerning the new entry is communicated to the data processing nodes for verification thereof. The system records the new entry when verified, to its corresponding given chain. The system includes a filter arrangement for limiting communication regarding the new entry to be made only to a subset of the data processing nodes of the system for verifying the new entry.
