Abstract:
A distributed ledger system (1) comprises: a processor (21); a memory (22); a plurality of participation nodes (ND) that store each ledger (23) in which transactions are recorded, in the memory (22); and a verification node selection device (4) that performs verification node selection whereby a plurality of verification nodes are selected for verifying transactions, from the plurality of participation nodes (ND). For verification node selection, the verification node selection device (4): calculates a score pertaining to at least the transaction processing speed or reliability, for each of the plurality of participation nodes (ND); and determines the plurality of verification nodes from among the plurality of participation nodes (ND), by selecting at least a prescribed number of participation nodes having a high score. Each of the selected plurality of nodes forms a consensus by verifying transactions.
