The only way to prevent these attacks is to force somebody to provide something of value to vote in the reputation system. That something of value could be energy (proof of work), time, money, their own reputation, tokens from a fixed wallet (just kicking the can down the road), or many other things.
The "Sybil attack" on reputation-based systems isn't the only one worth worrying about. Another one is incentives - some people may be very strongly driven to harm another person's reputation (see http://www.bloomberg.com/features/2016-benjamin-wey/ http://www.bloomberg.com/features/2016-benjamin-wey/ for example).
- illumin8 11y agoHaving it cost credits or tokens would just mean the wealthy or powerful can trash the reputation of others. Yes, the incentives you talk about are really the reasons why someone would want to trash your reputation. Some people get angered by simply getting cut off in traffic, and imagine a crazy person being able to trash your reputation because they didn't like the way you looked at them...
- nosuchthing 11y agoSurely nothing could go wrong if a voting system requires money or sacrifice of resources.
- nickpsecurity 11y agoYou've just described the American electorate. People get elected largely on the basis of who gets enough money and marketing. Big companies and wealthy individuals outspend most of voting America combined. So, elected officials work for them instead. Overtime, result was a one sided, rigged econkmy benefiting the rich and elites almost exclusively that we call a plutonomy. In other words, what you propose is very dangerous and needs more review/revision to trust.
