Blockchain use cases for food traceability and control
what
study to identify potential benefits from using blockchain technology for food traceability and control
when
2017
who
Axfoundation
SKL Kommentus (part of The Swedish Association of Local Authorities and Regions)
Sustainable Public Procurement - a collaboration between the Swedish county councils and regions
Martin & Servera (Sweden’s largest food service company)
Kairos Future
purpose
Identify the current state of food traceability and control
Identify technologies and projects that can be valuable in designing blockchain solutions
Identify blockchain technologies and projects that can be applied within food traceability and control
Show examples of how the current processes can be improved using blockchain technology.
Write a report and communicate the results to public authorities, the retail and food industry to stimulate interest and knowledge of the potential with the blockchain technology

challenges
establishing reliable provenance
preventing fraud and counterfeiting
effects on public health and the environment
reduce financial costs of unnecessary recalls of food products
traceability and control
possible without blockcahin
benefits with the blockchain
the data cannot be manipulated
the level of privacy to enforce can be decided by the participants in the system
the supply chain can secure traceability and control without all participants disclosing all their customers and suppliers to a central party
creates trust in low cost IT solutions
you can use email, word, mobile phones etc. and still be sure data is accurate (e.g. allows rural farmers and independent truck drivers to integrate with the system)
blockchain - identified areas of use
conditions at the production facility
problem
conditions at the product sites are difficult to verify
labor conditions
environmental conditions
quality control in production
solution
use blockchain to make it difficult to falsify or misrepresent conditions in production
store a digital representation of the conditions (such as a photo or a digital file) at the production facility or in a mobile app
publish a verification of the same files, a digital fingerprint in the form of a hash in the blockchain
time and location can not be manipulated as it is recorded in the blockchain
an inspector can verify that the digital representation of the condition corresponds to the actual conditions at the facility and that the outcome /production corresponds to the one reported to the blockchain
tracking of food volumes in the supply chain
problem
bulk commodities often bought on a spot market are difficult or impossible to track
solution
with blockchain it is possible to track the total volumes bought and sold for each participant in the supply chain
benefits of using blockchain technology
no central party needs to be trusted in getting all the data on transactions and actors
still let volumes be transparent for everyone in the chain
examples
with the blockchain the volumes of organic soybeans sold cannot be higher than the volume of organic soybeans bought for any party in the supply chain
with blockchain it’s not possible to buy ordinary rice and mix it with a small portion of basmati rice and sell the entire volume at the higher basmati rice price since the tracked amount of basmati rice going in to the chain cannot be higher than the volume going out
tracking of food items in the supply chain
put a unique identifier such as a barcode, QR code, or a RfID transmitter to package of food or any item
Compared with existing technologies, the blockchain can easily regulate who gets access to the information and identities behind each product
Integration between regular transaction data and more complex data such as sensor data of temperature and humidity can be directly connected to the product
cost and speed of implementation can probably benefit from an integration with existing product IDs such as the ones provided by GS1
