This is a slightly enhanced version of scenario 1 where Bob wants to publish the asset onto the Blockchain, but doesn’t want to directly reveal his ownership.
In this situation, Bob first creates a deterministic sub-key from his public key (see “A method and system for verifying ownership of a digital asset using a distributed hash table and a peer-to-peer distributed ledger” for details of this process) to represent the asset. This asset then publishes details about itself onto the Blockchain.
Once again, in this situation, there is no termination date for the asset.
The state machine for this scenario is the same as that for scenario 1.
