Valid concerns, but outside of crypto space, imho. Blockchain can ensure you that product was not "swapped" along the way, it can't police the company that created a product. It proves to you that your Rolex was actually built by people who own rolex private key, but it tells you nothing about how honest those people are. For that we need to rely on old school social reputation system.
hmm that is true, I guess this doesn't change the existing "trust" system we have today, just makes sure that from when It leaves that place and gets to me it didn't change at all.... I guess I feel a little better about it ... for now :) Thanks for pointing that out.
