Ethos Markets let you trade on someone's reputation. Every Ethos member can create a market, and anyone can buy or sell votes in it.
When people buy trust votes, the trust price goes up. When they buy distrust votes, the trust price goes down. The price reflects how the community values that person's credibility in real time.
If you believe in someone, you can back them by buying trust votes in their market. If others agree and buy too, the price rises — and your position becomes worth more.
Market creators also earn a cut of every buy transaction, so there's an incentive to build your reputation and grow your market.
