47### Reputation Authority
48Handles a public list of accounts that have been verified, in order to give some kind of trusted certification to an user's account.
49Can be runned by a collective, so for example, a group of people that work together in a project, can run a Reputation Authority, that will 'validate' trusted user's accounts.
