Ownership request is the TDNSYS process’s way of preventing double spending. Anybody in the possession of a TDN Signature may request ownership of the value associated with that TDN. TDNSYS will cancel the TDN and create a new Active TDN for the same value. It should be noted that splitting and consolidating a TDN with another TDN is also a way to obtain TDN ownership.
Sometimes the owner of a TDN may request ownership in order to be sure that the TDN has not been compromised.
