San Francisco-based startup Chronicled has completed a technical pilot aimed at demonstrating a new cryptographic method for transferring data and information related to trade items anonymously.
The pilot allowed multiple parties to verify an object’s identity and provenance using its Serialized Global Trade Item Number (SGTIN) without directly interacting with one another.
A Serialized Global Trade Item Number (SGTIN) is a universal identifier that provides a unique identity for physical object anywhere in the world, for all time. It allows for the identification of an item as it moves through multi-stage supply chains, which can often involve multiple custodians and geographic locations.
The pilot applied a cryptographic verification model developed by University researchers at UC Berkeley and MIT called Zero Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) to enable secure and anonymous transfer of possession and/or ownership of SGTINs within multi-party supply chains.
