1. A method performed by one or more computing systems of a network of network nodes for preserving privacy of obligations during a network scan, the method comprising:
under control of an initiator network node,
generating a scan identifier based on an initiator identifier of the initiator network node and a timestamp;
signing an initiate scan request using a first private key of a first public/private key pair;
selecting a nominated network node from the network of network nodes; and
sending to the nominated network node the initiate scan request that includes the scan identifier; and
under control of the nominated network node,
receiving the initiate scan request;
signing the initiate scan request using a second private key of a second private/public key pair; and
initiating a scan request by sending to a receiving network node the initiate scan request that is signed using the first private key and the second private key.
