Abstract
Techniques are described for managing ownership and transfers of physical objects using information stored on a distributed ledger such as a blockchain. A distributed ledger may securely store object data describing the current owner(s) of an object, the previous owner(s) of the object, the history of transfers of the object, and/or other information regarding the object. Use of a distributed ledger may provide an immutable, readily auditable record of the current ownership and ownership history of the object. Each user participating in the system may be assigned a unique identifier to be used for conducting transactions on the distributed ledger network. A user may also be provided with a digital security token such as a cryptographic key that is useable to authenticate the user and enable access to the object data stored on the distributed ledger(s).
