I am working on p2p reputation network in Ethereum. https://github.com/kwikiel/p2p-trust-network https://github.com/kwikiel/p2p-trust-network Often it's useful to be able to trust an online identity, i.e. for peer-to-peer lending sites, peer-to-peer home exchange sites, work assignments, etc. Most often the various platforms (like Couchsurfing, Uber, BeWelcome, Loanbase, Localbitcoins etc) will have some built-in support for ratings; user account A can leaving positive feedback for B after A and B has had an interaction on that platform. The ratings never leave the platform. There are usually no ways to see the difference between a conman creating yet another fake account and a newcomer to the platform. It is impossible for an outsider that have been scammed on one platform to leave a negative feedback warning users on another platform about the scammer. What we need is a global network-of-trust system. It should be truly peer-to-peer, it should be based on open standards and open source. Just the risk of getting negative feedback on such a network could be enough deterrent to avoid certain types of scam.
