Tracking tangible asset ownership and provenance with blockchain

Blockchain transactions are recorded in a shared and append-only repository that multiple parties verify, validate, and agree-upon. While initially used to keep track of digital assets, blockchains now track the ownership and provenance of tangible assets. An inherent challenge in using blockchain for this task involves keeping the status of a tangible asset in the physical world in sync with its non-fungible token on a blockchain. While several blockchains are already being used in this manner, specific implementation details are fragmented. In response, this study examines four stages of tracking tangible assets using a consortium’s permissioned blockchain, including: design and governance of a blockchain, asset creation, asset transfer, and asset retirement. Based on this analysis, this study proposes a framework of risk considerations and control objectives to evaluate the extent to which a unique blockchain serves as a reliable transaction repository for tracking the ownership and provenance of tangible assets
