Would it be possible to implement a decentralized darknet market, that works on reputation similar to how ethlance uses smart contracts, and eth for payment.
Furthermore if someone created such a market with a 0.1% fee would it be used, or would people create a clone with 0% fees?
I think people like having escrow.
I'm sure if someone built the site it'd get used, but 0.1% is a shockingly low fee. If you had the same kind of volume on is as hansa gets, it would pay less than minimum wage.
