Why isn't a basic version of proof of work a reasonable approximation of that for the time being? Ex. to provide a review you must also provide a value that when postpended to your review gives a hash containing some properties that scales with the number of reviews. This doesn't solve decentralized reputation at all but does prevent review bombing.
- SamPatt 9y agoIf the buyer leaves a review after making a purchase, that's effectively a small proof of work in and of itself, and you can only leave one review per purchase. We haven't seen review bombing attempted yet, but if someone were willing to pay a bunch of fees then I suppose it is possible to do.
- IncRnd 9y agoIn book publishing an author can purchase copies of their own books in order to increase purchases by others. This effect is actually common in many industries, even in mobile apps :)

- jcoffland 9y agoSo OpenBazaar's no worse than preexisting systems in this respect.
- hnarn 9y agoIt's also borderline an unsolvable problem, because how do you identify "legitimate" customers in an anonymous de-centralized system, when it's even too complicated to achieve in a centralized system?
- heavenlyblue 9y agoAssign a cost of creating a single anonymous identity: you've got to send xx amount of bitcoin to an unspendable address.
- jononor 9y agoThat is somewhat analogous to proof of stake, I guess?

- tylersmith 9y agoThere is a dichotomy in real cost/benefit ratio for PoW systems as spam control between real users and attackers. Attackers have more to gain from accepting the PoW penalty than users do. There is no difficulty of PoW that would both deter attackers with a financial motive and be reasonable for average users.
- zaarn 9y ago>gives a hash containing some properties that scales with the number of reviews That woudl IMO mean that once you have 10k reviews you can scam some customers without worry.
- nosuchthing 9y agoWhat? A spammer could easly bypass that with capital/hardware.
- dmichulke 9y agoAnybody can do anything with enough capital and hardware :-) The question is always just "Will the cost of fraud exceed the benefits of fraud" and if that is true, no one in his right mind will do it.
