What is Humanity (H)?

Deep Dive

1. Purpose and Value Proposition

Humanity Protocol addresses a core Web3 problem: proving an online account belongs to a real human without compromising privacy. In an era of AI deepfakes and Sybil attacks, it offers a decentralized identity layer that lets users own and control their digital identity. The goal is to enable trustless applications—from fair token distributions to reputation-based lending—by ensuring participants are unique humans.

2. Technology and Architecture

The network is built as an Ethereum-compatible zkEVM Layer-2, using the Polygon CDK for scalability. Its core innovation is Proof of Trust, a Sybil-resistant mechanism that combines palm-scan biometrics with zero-knowledge proofs (ZKPs). Users scan their palm locally; the device creates an irreversible hash, not storing the raw image. ZKPs allow the chain to verify uniqueness without accessing biometric data. This architecture supports selective disclosure of credentials (e.g., age verification) while preserving privacy.

Conclusion

Humanity Protocol is fundamentally a privacy-preserving infrastructure that turns verified human identity into a portable, secure credential for the decentralized web. How will its Proof of Trust mechanism evolve to meet increasing regulatory and technical demands for digital identity?
