I don't think "proof of work" works here because upvoting/downvoting content needs to be cheap... how do you make it expensive for a dedicated malicious force but cheap for legitimate ratings? Proof-of-work as a sort of "sign-on" to enable propagating a new "account"? That is, you need to have 1 Ghz-hour of wasted computation in order to introduce a new cryptographic hash into the network as a sort of "payment to create an account"? Again, a dedicated spammer could have a machine farming accounts 24/7 while this "payment" to create an account would be frustratingly expensive to a new user.
- darkmighty 12y agoThe user wouldn't have to pay anything to create an account, just to vote. Sure, spammers can farm large amounts of reputation through botnets, but that's really expensive: you're putting a cost on it. The returns are already not so high for disseminating this kind of spam. Having no reputation wouldn't mean you can't do anything -- just that what you do is less trusted and has lower priority.
