Karle Fellowship Final Report: Development of a Chemical Blockchain with Biased Detection of Matched Taggants
Abstract
While cryptoledgers, the central novelty of blockchain technology, offer the possibility of decentralized, remotely recorded, and trustworthy enforcement and tracking systems, pure digital instantiations fail to fully address the physicality of many applications as well as the need for embedded information in the physical good itself. A possible approach when applying cryptoledgers to physical items has been to include a taggant with the item and to use this presumably uncounterfeitable tag as a physical reference for a digital cryptoledger. Such a scheme requires truthful, competent reporting to the cryptoledger across multiple transactions and presents few opportunities and no physical markings or verifications that the integrity of the tagged item is being maintained across all transaction levels. This report proposes and explores theoretical methodology for supporting chemo-physical solutions to this problem, specifically, technology from a diverse array of sources that might be adapted and used to create a cryptoledger scheme capable of operating independently of standard computational and networked protocols via chemo-physical technology, but nonetheless capable of supporting some digital component to enable faster communication and two-factor authentication forgovernment logistics hygiene and regulatory enforcement.
