Proof of Personhood

Nachweis der menschlichen Identität.

Inhalt steht zur Übersetzung an. Die englische Version wird angezeigt.

Proof of Personhood aims to solve the 'Sybil attack' problem in decentralized systems. It ensures 'one person, one vote' by using biometric scans (like iris recognition) or social networks of trust (vouching). This is essential for fair airdrops and democratic governance in DAOs.

🧒 Erkläre es wie einem 5-Jährigen

It's like getting a stamp on your hand at a carnival so the staff knows you're a real person and you can't go back and get 10 free ice creams by pretending to be 10 different people.

🤓 Expert Deep Dive

Prominent examples include Worldcoin (Orbs for iris scanning) and Proof of Humanity (video verification and vouching). It creates a unique 'human-ness' score that protocols can use to filter out bot activity.
