Blockchain has long been touted as having transformational potential. Yet, the commercial adoption has been slow. As with any cutting-edge technology, commercial adoption usually requires some tipping point. For adoption of blockchain-based supply chain, the tipping point may just have occurred.
According to a recent article, starting in September 2019, Walmart and its Sam’s Club division will require suppliers of fresh, leafy greens to implement real-time, end-to-end traceability of products back to the farm using a digital ledger. They plan similar mandates for other fresh fruit and vegetable providers within the next year. This will apparently require more than 100 companies to use this blockchain-solution.
The use of blockchain to increase the efficiency and reduce costs in various supply chains has long been recognized. The applicability to the food supply chain has some additional advantages. The advantages include:
- the ability to track products to their original source (traceability)
- remove middlemen and reduce manual steps (efficiency)
- improve food safety by tracking and recording temperature of transport and preventing substitutions or tampering (safety)
- more quickly address contamination or other health issues (health)
- more efficiently order food based on user demand and supply chain availability to avoid waste or shortages (inventory management)
Additionally, blockchain-based supply chains can help comply with various legal requirements. For example, the Food Safety Modernization Act (FSMA) was implemented to transform the nation’s food safety system by shifting the focus from responding to foodborne illness to preventing it. FSMA requires various steps including supply chain risk management procedures and traceability, foreign supplier verification, ensuring and documenting appropriate temperature controls during shipment, and much more. Blockchain-based supply chain technology is ideal for managing these tasks.
The innovations in this space are rapidly increasing. Competition among startups, major food retailers and IT behemoths is also increasing. As often is the case when this market dynamic exists, we are seeing an increase in the number of patents being filed in this space. The following are a few examples of supply chain related patents relevant to the food industry.
|System and methods to ensure asset and supply chain integrity||PCT/US16/46446|
|Food-logistics supply-chain model||CN 201310335802|
|Method and apparatus for managing and providing provenance of product using blockchain||US20170262862|
|Method for tracing food products||EP1489537|
|Method for monitoring origin of a liquid food, fruit juice or vegetable juice preparation||US20120066098|
|Tamper evident point of containment, inventory and accountability system and method||WO2012019201|
As this competition heats up, it is likely that patent filings will continue to increase.
