Framework for representing physical assets using tokens

Апстракт

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.
