zkPass is a decentralized oracle protocol that converts private data from any HTTPS website into cryptographically verifiable proofs on-chain. It is built on zkTLS, a novel combination of three-party TLS (3P-TLS) and hybrid zero-knowledge cryptography.
The key breakthrough is simple but powerful: users can prove facts derived from web data without OAuth logins, API keys, or trusted intermediaries.
All proofs are generated locally on the user’s device or browser, meaning raw personal data is never uploaded, stored, or shared.
What Can Be Proven with zkPass
zkPass enables selective proof generation across many real-world data domains, including:
Legal identity such as passports or national IDs
Financial records like balances, transactions, or credit scores
Healthcare data including prescriptions or medical history
Social and behavioral proofs from online platforms
Professional and educational credentials
Digital assets, gaming accounts, loyalty points, and RWAs
Only the required attribute is revealed. Everything else stays private.
Why zkPass Matters
Existing verification systems rely on centralized APIs, OAuth permissions, or custodial data providers. These models introduce privacy risks, censorship, and trust assumptions. zkPass introduces a new verification paradigm.
Privacy-Preserving by Design
Sensitive data never leaves the user’s device. Proofs disclose only what is necessary.
Verifiable Integrity
zkTLS extends standard TLS into a three-party model, guaranteeing data provenance and authenticity.
Universal Compatibility
zkPass works with any HTTPS website, no special integrations or licenses required.
Anti-Cheating Guarantees
Template-based verification prevents manipulation of requests or responses, making proofs resistant to fraud.
High-Performance Proofs
Using the VOLE-in-the-Head algorithm, zkPass generates proofs in milliseconds while remaining publicly verifiable.
Trustless Attestations
Decentralized MPC nodes verify integrity before accepting proofs, ensuring zkSBTs and attestations cannot be forged.
Public vs Private Data
Public data is open but lacks personalization. Private data is rich but protected and difficult to verify. zkPass bridges this gap by turning private data into verifiable proofs without revealing the data itself. This enables private information to safely participate in open digital systems.
Use Cases Across Web3 and AI
zkPass proofs can be used in digital identity systems, DeFi lending, DAO governance, compliance workflows, AI agents, DePIN networks, and beyond. Any application that needs trust without exposure can integrate zkPass.
Conclusion
zkPass is redefining how trust works on the internet. By transforming private web data into privacy-preserving, verifiable proofs, it unlocks a future where identity, reputation, and real-world data can interact with blockchains and AI—securely, universally, and without intermediaries.
