"Blockchain is just a digital ledger, a digitized record of whatever data is added by its members, with no ability to verify the accuracy of the underlying data itself."
"Because the truth of that data isn’t actually evaluated, there’s no aspect of blockchain technology that can make sure that the cage-free egg is really cage-free or that the lettuce is actually free from contamination."
"Rather than chasing a paper trail for days, they can get to the source of a tainted head of lettuce within seconds."

^That's a sales pitch. Reality: any farm or packinghouse worth their salt can already find their product w/in 2hrs. If it takes longer than that, something's up.
Omg Walmart is really out here selling "it takes days to trace stuff!" as the norm, instead of what it really is- a bright burning signal that there's something deeply pathological about their supply chain.

"It’s not clear why blockchain is the best tech for transforming the food industry, & it may not be. It may just be that it’s getting attention right now, particularly as tech experts look for ways to transfer their experience & make their mark in the burgeoning agritech sector."
Translation: blockchain does nothing to improve food safety. It DOES do a lot to promote blockchain bros' careers.

(And also makes retailers with janky supply chains look like they're fixing it.)

The end. That's literally it. In conclusion, fuck blockchain.
