One interesting use case I’ve heard about (for blockchain) is supply chain verification / provenance. Does anyone with more knowledge or experience have insights on this one?
- joosters 6y agoIt doesn't help here any more than existing solutions. How exactly is a distributed collection of blockchain miners meant to validate (e.g.) a sensor that is being used to show that a shipment of chilled meat was always at 3'c or cooler? Answer: they can't. The only part of a blockchain that helps verification/provenance is its append-only nature, and that feature is widely available with much simpler mechanisms.
- FabHK 6y agoYes. If you trust someone not to manipulate the sensor (or whatever you use to go from physical world to digital), then you might as well trust them not to manipulate the Excel sheet collecting all the data.
