The patent also specifies that the system will not be made limited to retailers. Individuals can also make use of the system to resell products.

Walmart further shed light on the proposed system:
“By one approach, the transfer from one seller to the courier may require signatures from both the sender and the courier using their respective private keys. The new transaction may be broadcasted and verified by the sender, the courier, the buyer, and/or the other nodes on the system before being added to the distributed delivery record blockchain. When the package is transferred from the courier to the buyer, the courier may use the courier’s private key to authorize the transfer of the digital asset representing the physical asset from the courier to the buyer and update the delivery record with the new transaction.”
