This document establishes a DLT agnostic architecture for physical assets using NFTs which includes: An algorithmic data method for generating decentralized identifiers (DIDs) from physical assets with immutable unique identifiers, such as serial numbers. Processes for utilizing off-chain trust anchors, to establish proof of real-world human and machine generated events and information, that tie a real-world asset to its digital representation. A DID method scheme to enable DID Registry interoperability, so the Digital Representation can be stored, resolved, or transferred to any compliant DID Registry. This document is applicable to... Serialized physical assets with unique immutable identifiers, such as serial numbers. The systems, machines, organizations, and natural persons that process them. This document is not applicable to... Fungible assets and non-serialized, non-fungible assets (unique assets without immutable identifiers). Digital assets and identifiable bundles of assets Any specific DID method, blockchain / DLT protocol, or NFT standard.
