Anomaly detection in distributed ledger systems

A network node configured to maintain a distributed ledger in coordination with a plurality of network nodes, the network node comprising:

• a processor configured to execute computer readable instructions including on a non-transitory memory;
• and
• a non-transitory memory including a first copy of the distributed ledger and computer-readable instructions, that when executed by the processor, cause the network node to:
• determine a characteristic value based on information associated with the first copy of the distributed ledger, wherein the plurality of network nodes store respective copies of the distributed ledger and each copy of the distributed ledger stores blocks of transactions that were added to each copy of the distributed ledger based on a consensus determination between the plurality of network nodes;
• determine whether a current transaction to be added to the distributed ledger satisfies the characteristic value;
• generate an anomaly indication indicating whether there is an anomaly based on a function of the current transaction in relation to the characteristic value;
• determine whether to add the current transaction to the distributed ledger based on the anomaly indication;
• and
• transmit the anomaly indication to other network nodes of the plurality of network nodes.
