Quick Take

  • The Proof of Personhood Passport (PoPP) is a “transportable proof of identity for the Web3 space” that aims to increase Sybil resistance and protect quadratic algorithms used for voting and funding
  • We review the three proof-of-personhood protocols that currently carry the most weight in determining one’s PoPP personhood score: Proof of Humanity, BrightID, and Idena
  • The PoPP holds potential for a variety of use cases such as enabling decentralized universal basic income (UBI) schemes; supporting the maturation of DAO governance systems that require verifiable credentials; and enabling Sybil-resistant airdrops, yield farming, and NFT distributions
