Anti-Sybil Protocol using virtual Pseudonym Parties
The Proof-of-Individuality (POI) protocol is an anti-sybil protocol based on Bryan Ford’s pseudonym parties (2008)
Global meet-up events happen simultaneously across the world, continuously throughout the year. The proof is based on the fact that you cannot be in two places at once.
Bryan Ford wrote that the tension between anonymity and accountability may not be fundamental, but merely an indication that our current mechanisms to provide them are too primitive. He also wrote that pseudonym parties appear to be the only proposed solution that can address both strong accountability and privacy at the same time.
The Proof-of-Individuality (POI) project takes Bryan Ford’s vision into the digital space, and lets people meet up using video hangouts. The proof is based on the fact that you can’t be in joint attention with more than one hangout at a time, without anyone noticing it.
An interesting future for the protocol would be to use Mirosoft’s new holoportation technology for the hangouts.
Once verified, you receive an anonymous token that is valid for one month.
You have to get a new token the next month, and your new token will not be traceable to your previous token, making the tokens very anonymous.
POIs are indexed on the block-chain and searchable, and you could build more complex IDs on top of it. A POI in itself is anonymous and controlled by the owner who has the corresponding private key. You can link your POIs together, at the cost of decreased anonymity.
This is a draft of the full POI system
