What Is Humanity Protocol?
(Source: Humanityprot)
Humanity Protocol (H) is a zkEVM Layer 2 blockchain built on Polygon CDK, designed to tackle the longstanding challenge of distinguishing humans from machines in the Web3 ecosystem. Its primary goal is to deliver verifiable, composable, and Sybil-resistant Proof-of-Humanity (PoH) for decentralized applications, all while safeguarding user privacy.
By modularizing identity verification, Humanity Protocol empowers developers to easily confirm that users are genuine and unique individuals across DeFi, DAO, airdrop, voting, and compliance scenarios, while ensuring users retain full control over their personal data.
Dual-Layer Biometrics: Balancing Usability and Security
Humanity Protocol features a dual-layer biometric architecture, striking a balance between accessibility and fraud prevention.
- The first layer uses mobile palm print scanning. Users can complete initial verification directly on their smartphones, providing a fast, scalable process that lowers the participation threshold for global users.
- The second layer utilizes infrared palm vein scanning. By capturing the unique subcutaneous vein patterns, the system offers robust anti-counterfeiting protection that is nearly impossible to replicate, making it ideal for verifying humanity in high-value or high-risk environments.
This layered approach enables Humanity Protocol to support both mass adoption and high-security use cases.
Zero-Knowledge Proofs
During identity verification, Humanity Protocol leverages Zero-Knowledge Proofs (ZKP) as its core privacy safeguard. All biometric data is stored on-chain exclusively as encrypted proofs, never as raw images or reversible information.
Users can prove to applications that they are real and unique individuals without disclosing any specific biometric traits or personal details. Even if system data is compromised, sensitive information cannot be reconstructed or misused. This approach ensures identity verification truly aligns with Web3’s fundamental principles of privacy and trustlessness.
Self-Sovereign Identity and Verifiable Credentials
Humanity Protocol adopts a Self-Sovereign Identity (SSI) framework, granting users complete control over their identity. Users decide which information to share, when, and with whom, and can revoke access at any time. The protocol issues multiple types of Verifiable Credentials, such as Proof-of-Humanity, age verification, KYC/AML compliance status, educational background, and professional qualifications. These credentials are interoperable across platforms, making identity a truly portable and composable Web3-native asset.
Decentralized Verification Network
Humanity Protocol’s verification process is maintained by a decentralized network of identity verifiers and zkProofers, ensuring no single party controls the system. This architecture enables secure support for diverse applications, including Sybil-resistant airdrops, private DAO voting, real-time on-chain identity verification, and privacy-conscious regulatory compliance, all while maintaining transparency and resistance to censorship.
H Token: The Core of Network Security and Governance
H is Humanity Protocol’s native ERC-20 token, serving as the backbone for both economic activity and governance. zkProofers and identity verifiers must stake H tokens to guarantee honest verification and network security. H also covers protocol network fees and grants holders governance rights over key decisions, including upgrades, parameter changes, and fund allocation.

Conclusion
Humanity Protocol combines zkEVM, dual-layer biometrics, zero-knowledge proofs, and self-sovereign identity into a privacy-first human verification infrastructure. It not only solves the problem of bots and Sybil attacks in Web3, but also redefines how identity is verified and used in a decentralized world. As AI and automated accounts proliferate, proving your humanity while protecting privacy becomes the foundation for next-generation Web3 applications. Humanity Protocol aims to set the standard in this evolving space.
