It worked very well and was quite delightful - definitely want to be doing more of these in future. I think people will come to expect this kind of no-friction payment experience and Bitcoin will need to match it, so here are some notes on what's involved. > > 3) Have some kind of decentralised reputation network. I spent some time thinking about this, but it rapidly became very complicated and feels like an entirely separate project that should stand alone from Bitcoin itself. Perhaps rather than try to make a global system, social data could be exchanged (using some fancy privacy preserving protocols?) so if your friends have decided to trust seller X, your phone automatically trusts them too. A reputation network might be an interesting idea, or several different networks with different curators (to prevent complete centralization), like how the US credit score system has three main companies who track your score. Something like a GPG ring of trust, with addresses signing other addresses would work well, if some sort of Stealth address or HD wallet root was the identity gaining the reputation, then address re-use wouldn't have to be mandatory. -------------- next part -------------- An HTML attachment was scrubbed...
