Who would have thought, it's actually real: https://www.ibm.com/blockchain/solutions/food-trust. It seems to be based on Hyperledger Fabric, which apparently does not require proof-of-work. That's amazing, and thanks for mentioning it. This is the first non-disastrous blockchain project in active use that I've ever heard of.
It’s overkill for lettuce sold to Walmart, but I can see why Walmart wants to try it. I am curious to see how we can implement and use blockchain appropriately in the supply and value chain of food. Walmart mandating lettuce blockchain and patterning with IBM is a good start, but honestly at this level, it can also be done with just well managed database systems. But I am all for it! I am excited to see where this will lead.
I also can...intuitively only because I can’t articulate it or prove it.. see this as ‘laying down of the road’ before the town is built. Exciting.
2. There is already a lot of technology in what you eat. Mechanization in factory style farms, cold supply chain, blockchain for lettuce at Walmart..the stock system..the inventory..everything. Not to mention that your food chain is owned by agri fertilizers and pesticide companies..and gmo seed. Bayer owns Monsanto now. The company that used slave labor in nazi concentration camps bought out the company that made agent orange. And that’s who is making your food and medicine.
3. I am also frustrated that farming methods aka hard work meant to feed a lot less people is now expected to feed close to 10 billion by 2050. On less land.
