The blockchain can prove that I bought the car and own it now. But that has never been the problem. Trust is still required because I need to trust the seller

The blockchain can prove that I bought the car and own it now. But that has never been the problem.
Trust is still required because I need to trust the seller that the car isn't a lemon and he didn't put explosives into the back seat.
The blockchain solves none of that.
- yenwel 4y agoblockchain could be used to put reputation systems on them.
- bfung 4y agoHow would that work? We have Yelp, Google reviews, Amazon reviews… how would something like that work on a blockchain/ledger and not be gamed just like the review systems we have now?
- Mordisquitos 4y agoAnd how would we avoid this reputation blockchain from being populated by maliciously deceptive information, be it positive reputation promoted by the business through bribed or fake customers, or negative reputation promoted by unethical competitors?
- ben_w 4y agoReinventing existing trust mechanisms but with an extra (computationally expensive) layer of things that can go wrong is the opposite of an improvement.
- konschubert 4y agoI see no reason why a reputation system needs distributed consensus. It needs asymmetric encryption (signatures), but not a blockchain.
