BrightID lets all sorts of applications make sure their users don't have multiple accounts so that everyone has a fair share and a better experience. It solves the unique identity problem through the creation and analysis of a social graph. BrightID works by creating a social identity network that allows people to prove to applications that they aren’t using multiple accounts.

Thus BrightID enables new experimental currencies, voting systems, benefit programs, and all sorts of other projects for which it's essential that no one gets to create multiple accounts. As all users have their own unique BrightID.
