Proof of Personhood Meaning

Proof of Personhood is a Consensus and Identity Mechanism designed to Prove that a blockchain address is Owned by a Unique Human Being rather than a Bot or an AI. This is one of the Hardest Problems in computer science, known as Sybil Resistance. In a One-Token-One-Vote system, a Whale has all the power.

In a One-Person-One-Vote system, you need Proof of Personhood to prevent one person from creating a Million Wallets.There are several Technical Approaches to this. Worldcoin uses Biometrics (scanning your Iris with a device called the Orb) to create a Unique Digital ID.

BrightID uses Social Verification (having people you know Vouch for you). Idena uses Synchronized Turing Tests (solving puzzles at the same time as everyone else in the world).

Each method has Trade-offs between Privacy, Convenience, and Security.Proof of Personhood is essential for Universal Basic Income (UBI) and Quadratic Voting. If you want to give a Monthly Payment to Every Human, you must be able to Identify every human without Double-paying someone who has Multiple Accounts.

In Quadratic Voting, the Number of People who vote for an idea is more important than the Number of Tokens they have, which Levels the Playing Field and makes the system More Democratic.The Controversy around Proof of Personhood is Privacy and Surveillance. Many people are Uncomfortable with the idea of a Global Biometric Database (like Worldcoin).

They fear it could be used by Governments to Track and Control citizens. The Holy Grail of this technology is Private Proof of Personhood, where you can Prove you are Human using Zero-Knowledge Proofs without ever Revealing your Name, Face, or Location.
