This demo shows the status of a digital asset called "Ford Prefect 999", which has a history of ownership changes.
A transfer of ownershiplike this requires the signature of the current owner (and knowing their private key), and the transfer
blocks all the way from the creation block of the asset can be traced and verified.
Inside Xanadu the timeline datamodel holds all the transation history (which is a cryptographically securely signed blockchain)
under a simple "Key" that is the name of the asset (in this case "Ford Prefect 999").
If you need to verify things, then you pull all the data blocks out of Xanadu and simply recompute the SHA256 signatures using
the public keys of owners at any link in the chain.
A potential application can be a medical image data market place for sharing, transaction, exploration for AI in
relation to Xanadu Based CBIR System for automated diseases classification & diagnosis.
