Abstract
A comprehensive system for chain-of-custody for hardware devices and their components. Specifically, as the components, assemblies and the hardware device are manufactured and/or assembled, non-fungible tokens (NFTs) are generated for each component, assembly and the overall hardware device that indicate that the component, assembly or hardware device is in a certified/verified good state (i.e., have not been tampered with). The NFTs are generated using measured authenticity characteristics (e.g., electro-magnetic, heat, weight, dimensions and the like) of a corresponding component, assembly or hardware device as at least a portion of the input to the hash algorithm. The NFTs are subsequently communicated to a distributed trust computing network at which the nodes converge to verify an authenticity and certifiable state of the NFT, and blocks of data are generated within distributed ledgers that store the verified NFT.
