Raw materials travel through exploitative supply chains, premium goods are forged and and producers remain invisible. How can we stop this disconnection between people and their material items? How can we enable goods to change hands in a way that helps business with fair practices flourish? Project Provenance Ltd was founded with the goal of using technology to enable every physical product to come with it’s provenance. Through a successful Proof of Concept grant, we have integrated blockchain technology along a supply chain to allow interoperability of provenance information. The Development of Prototype grant will enable us to build a full prototype for supply chain traceability on the blockchain. Specifically, we intend to meets the needs of our primary market opportunity: Regulation and voluntary standards compliance in food supply chains. We seek to empower business with a consumer facing proof for the provenance of everything we eat - starting with high value items such as organic food, fish and beverages. The end-to-end prototype will integrate our PoC work with new R&D that will deliver an easy to use toolkit and further key operations, including: Item transformation (e.g. food processing), full verification of claims (e.g. certified organic) and item level data access (e.g. a digital marque). At the core of our system is the Proof-of-Provenance Tag (or “PoPTag”): This is a digital/physical ‘product’ that links a secure digital history to any respective physical item. PoPTags allows information to flow freely with goods without the need for intermediaries or data trustees – the weakness of current alternatives. We employ the unique features of blockchain technology so that control and ownership can fully lie in the hand of users. For the first time, customers all along a chain of custody will have access to authentic data about the journey and attributes of an item.
