Proof-of-Personhood demo at Blockchain-Summer-School 2017

Proof-of-personhood is a novel system to attribute exactly one cryptographic token to exactly one physical person. It uses linkable ring signatures to identify yourself as being part of the group. This gives you an anonymity-set the size of the participating group.
