A first chain of custody verifiable claim is received by a second entity from a first entity. The first chain of custody verifiable claim is signed by the first entity and specifies that an object was in the custody of the first entity. A distributed ledger is accessed to verify the first chain of custody verifiable claim. A second chain of custody verifiable claim is generated that embeds the first chain of custody verifiable claim and is signed by the second entity. The second chain of custody verifiable claim is recorded on the distributed ledger. The second chain of custody verifiable claim is provided to a third entity. The second chain of custody verifiable claim is configured to specify to the third entity that the object was in the custody of the second entity.
