Supermarkets like Walmart, Coles, to ultimately uphold blockchain systems
BLOCKCHAIN is an interesting technology, and financial services use cases aside, the technology is finally beginning to make a dent in the way logistics companies, retailers, and even manufacturers operate.
In the food industry, the technology is being seen as a way to track and trace the origin of food — from farm to fork as many like to say.
The idea is for farmers to tag the fruits, vegetables, and meat they produce and then commit that information to a blockchain platform that helps stakeholders transparently deliver that product to the end-consumer.
Tech Wire Asia recently wrote about Beefledger, a blockchain platform that is helping Australian beef producers deliver authentic meat to consumers in China, and allowing them to battle fake meat suppliers that diminish consumer confidence.
PwC Agribusiness Leader Craig Heraghty, however, recently told Australian media that blockchain systems are great in theory but there’s no guarantee that the system will deliver. Things might still go wrong along the way.
“The weakest link in the chain is not blockchain or any technology, the weakest link is the piece of sticky tape that puts the label on the package.
“You have to think like a fraudster and see where you can copy a label or a QR code.”
While Heraghty doesn’t really specify any particular blockchain solution as a problem, he does believe that “the illusion of traceability [provided by blockchain-powered systems] is a worrying trend”.
The solution? Truth be told, experts believe that ultimately, it will be the responsibility of supermarket chains to uphold and defend their blockchain system.
Nothing can prevent dishonest shopkeepers from tampering with labels and QR codes, but when supermarkets build and deploy such systems, it is their duty to make sure that the entire chain is foolproof.
Supermarkets — such as Walmart and Coles — who are already experimenting with the technology are sure to find a way to guarantee the trust that their blockchain system is intended to provide, gaining an edge on competitors in the market.
