Exploring Tokenized Product Passports for Circular Construction Supply Chains

Abstract: A token is a cryptoeconomic entity on a blockchain that can be used to digitally secure, represent, and trade assets. Existing research does not sufficiently explore the use of tokenization as digital representations of physical construction assets within the context of circular supply chains. Thus, this research explores why tokenization for circular construction may be helpful by employing a mixed methods approach via quantitative and qualitative analysis of expert surveys and a technical review of tokens. The contribution proposes scenarios of tokenization’s potential for blockchain-based product tracking and product passports for AEC.
