Re: Coffee chain
"What exactly would be the benefit of a blockchain in such a system, compared to a traditional centralized tracking system? I'm guessing there's no real benefit, just substantial costs."
More importantly, if the bean is going to end up at Starbucks why would anyone worry about its adventures before it got there - what happens to it after they've got their greasy little paws on it is sufficiently horrific that anything that happened to it before then pales into insignificance - no, since you ask, I don't consume Starbucks' made up coffees, even with a double shot of triple distilled unicorn pee.
