Abstract: A non-fungible blockchain token (NFT) transferable from wallet to wallet on a blockchain represents ownership of a physical diamond custodied in a secure vault. The NFT can be sold and resold to investors wishing to use the diamond as a store of value. The NFT owner, who may only be known by a blockchain wallet address, can communicate with the custodian, the issuer, auditors, and more by writing signal messages into the blockchain NFT. A diamond custody controller unit at the custodian includes a trusted program module to handle private cryptographic key functions and to output retrieval and shipping instructions when a signal message indicates the NFT owner instructs the custodian to move the diamond to a new custodian. The NFT owner can also write signal messages into the NFT to instruct other parties, such as auditors, to perform services relating to the diamond.

Abstract: A communication system facilitates the replication of display objects from first providers into displays provided, upon request from subscribers, by second providers. The first providers may specify which second providers or classes of second providers may incorporate the replicated display objects, and which portions thereof the second providers may customize. The second providers may select which available replicates they will display, and may customize them as specified permissible by the first providers. Changes made to the objects become available immediately to subscribers.
