What is proof-of-individuality? Proof-of-individuality, or proof-of-uniqueness, is the work required to prove that a user has exactly one account in a given network. It gets rid of fake accounts because a user can't create more than one profile very easily. Unlike other networks, it also gets rid of paid-for accounts, because accounts become non-transferable, due to the use of biometrics. Anonymous proof-of-individuality means that you can identify a single account as belonging to a unique user, without knowing the user's identity in the real-world. While Project Oblio's distribution may not rely on anonymized biometrics, future iterations are expected to include leading encryption techniques such as functional encryption to enable this. Project Oblio's proof-of-individuality algorithm is a metric. It calculates trust levels as to whether an account belongs to a unique user, not whether a user is definitively unique. A number of financial incentives are in place to make the cost of generating and maintaining a fake account more costly than competing methods of influencing the network.
