human.tech Joins the Predicate Ecosystem to Accelerate Zero Knowledge Identity Verification

Mar 5, 2025

Most identity verification systems today are intrusive; they require users to share personal data such as government-issued IDs, biometrics, or other sensitive information. In traditional finance, centralized databases store and control this data, exposing users to surveillance, data leaks, and censorship. Many crypto applications follow the same flawed approach, relying on centralized intermediaries to verify identity. However, this approach undermines the anonymity that blockchain technology natively provides. For blockchain-based systems to truly scale, they need identity solutions that do not compromise privacy.

Bringing Privacy-Preserving Identity Onchain

Developers on Predicate can now integrate Human Passport and Human ID, enabling privacy-first access controls directly into smart contracts. Human Passport (previously Gitcoin Passport) is an attestation framework that verifies personhood and reputation without revealing personal data. Human ID is a zero knowledge identity system that allows users to prove facts about their identity without exposing sensitive information.

By incorporating these identity systems into Predicate’s policy framework, developers can enforce transaction rules without relying on IP addresses, government IDs, or centralized KYC providers.

This unlocks new use cases:

  • Sybil-resistant DAOs: Prevent governance attacks without invasive KYC.

  • Fair airdrops: Distribute tokens based on verified uniqueness, not bot armies.

  • Private DeFi access: Restrict interactions based on reputation or compliance, while maintaining user anonymity.

Privacy as a Core Tenet of Decentralized Systems

As the ecosystem continues to expand, privacy remains essential to blockchain technology's promise of pseudonymity. Furthermore, the current reliance on centralized entities for verification and data storage introduces significant risks to decentralized applications.

Predicate's integration with human.tech represents a crucial step towards implementing decentralized, private, and trustless identity verification. As a result, users can maintain full control of their data when interacting with onchain applications.

About Predicate

Predicate is a network for simplifying transaction prerequisites. Through Predicate, users, developers, and communities define rules for on-chain interactions, integrating expressive pre-transaction logic into decentralized applications. These rules, like legos, can be stacked to form policies, which are enforced by the Predicate Network. For more information, visit: predicate.io.
