What is Humanity Protocol (H)?

Deep Dive

1. Purpose & Value Proposition

Humanity Protocol tackles Sybil attacks (fake identities) in Web3 by replacing centralized identity models with Self-Sovereign Identity (SSI). Users store encrypted biometric data locally, sharing only cryptographic proofs to verify humanity (Gitbook). This allows apps to confirm users are unique humans without exposing personal data, addressing a critical gap in decentralized ecosystems.

2. Technology & Architecture

The protocol combines palm-vein biometrics with zero-knowledge proofs (ZKPs) on a zkEVM Layer 2 blockchain. Key features:
- Proof-of-Humanity (PoH): Palm scans create unique biometric templates stored off-chain; ZKPs validate humanity without revealing raw data.
- Decentralized Storage: Private data remains user-controlled via encrypted nodes.
- Interoperability: Supports cross-chain credentials through DID/VC standards.

3. Tokenomics & Governance

The H token serves two primary roles:
- Network Access: Pays for identity verification and credential issuance.
- Governance: Token holders vote on protocol upgrades.
Total supply is 10B, with 2.12B circulating as of September 2025. While tokenomics emphasize decentralization, critics note 29% of supply is held by early investors (CoinMarketCap).

Conclusion

Humanity Protocol positions itself as a privacy-first alternative to projects like Worldcoin, prioritizing user ownership and minimal data exposure. Its success hinges on balancing biometric adoption with trust in decentralized systems. Can H become Web3’s universal identity layer, or will regulatory scrutiny around biometrics limit its reach?
