Proof of Humanity is a system that combines a web of trust, a reverse Turing test, and dispute resolution to create a fraud-proof roster of humans.

UBI is the first application built on the Proof of Humanity registry, and it is an anti-Sybil attack tool designed by Kleros.

UBI tokens will flow directly to an Ethereum address as soon as it is verified as human in the Proof of Humanity registry and begin the accumulation process, establishing a fair and ongoing distribution model. It provides universal liquidity, acts as a brake on financial coercion of public decision-making, and is tradable in all public markets.

The ability to develop a reliable self-sovereign identity verification process enabled by Proof of Humanity lays the foundation stone for building a universal basic income (UBI) mechanism that can benefit everyone on the planet.
