Abstract: A system, method, and apparatus for decentralized authentication and sale of a product is provided that, in some embodiments, comprises a distributed ledger, a first computing device associated with at least one real-world product owner, and a second computing device associated with a buyer. The distributed ledger generates and links a digital product identifier to at least one real-world product, wherein the digital product identifier is physically affixed to the at least one real-world product. The first computing device stores at least one owner digital wallet, receive at least one unit of currency, and transfer the digital product identifier. The second computing device stores at least one buyer digital wallet, transfers the at least one unit of currency, and receives the digital product identifier. The distributed ledger also determines one or more spatial parameters and generates and transmits a spatial output responsive to a spatial output request.
