Understanding the zkPass Infrastructure: Utilizing the zkPass Extension

zkPass is a groundbreaking oracle protocol that enables private internet data to be verified and proven on-chain without compromising user privacy. Built on advanced cryptographic foundations—specifically 3P-TLS and Hybrid ZK technologies—zkPass offers a unique way for individuals to prove data authenticity from any HTTPS website without relying on OAuth APIs or exposing sensitive details.

Its value lies in allowing users to validate information like legal identities, bank records, health data, and professional history through zero-knowledge proof (ZKP) computations—all performed locally and securely. The zkPass protocol supports applications across AI, DePIN, decentralized ID (DID), and financial services.

Key Takeaways

• zkPass enables users to prove private data verifiably and privately on-chain using browser-based ZKPs.
  
   
• Its three-party TLS model ensures data authenticity without compromising source or content.
  
   
• The protocol is compatible with any HTTPS website—no OAuth, API keys, or licenses required.

What is zkPass

zkPass acts as a privacy-first data oracle. It allows anyone to prove access to specific types of internet data—like government records or transaction history—without revealing the actual content. Its infrastructure is rooted in zkTLS, a customized implementation of the TLS standard that allows for zero-knowledge data proofing. These ZKPs are generated directly in the browser using memory-efficient cryptographic primitives, allowing fast, verifiable proofs at scale.

Why zkPass Stands Out

1. Privacy-preserving

Users can demonstrate ownership or qualifications without ever uploading or exposing their raw data.

2. Verifiability

With its reimagined three-party TLS (3P-TLS), zkPass confirms the source and integrity of private data, preventing tampering.

3. Broad Compatibility

It works with any website using HTTPS—no cooperation or API access from the site is required.

4. Decentralized Verification

By leveraging MPC nodes to verify data before generating proofs, zkPass ensures the integrity of on-chain attestations.

5. Anti-Cheating Mechanisms

Built-in safeguards confirm that data matches expected formats and sources, thwarting attempts to fake credentials or input.

6. Lightweight and Fast

Thanks to VOLE-based IZK (Interactive Zero-Knowledge), zkPass achieves millisecond-level proof generation directly in the browser.

Public Data vs Private Data

Public Data

Public data is widely accessible and shared openly by institutions such as governments. Examples include weather statistics, census data, or legislative records. While it may be rich in insight, this type of data is scrubbed of personal identifiers and typically used to promote transparency, research, or policy analysis.

Private Data

This includes any information that can directly or indirectly identify a person or confidential business information. Examples range from health records and banking credentials to social media activity or company IP. Private data is legally protected and must be handled with strict compliance protocols. The central principle behind zkPass is to enable use of this data in verifiable ways—without revealing its contents.

Private Data Types zkPass Can Prove

• Legal Identity: National IDs, passports, and licenses
  
   
• Financial Records: Account history, credit scores, and transactions
  
   
• Healthcare Information: Diagnoses, medical records, genetic data
  
   
• Social Interactions: Social media engagement, messaging patterns
  
   
• Professional Records: Work history, certifications, performance evaluations
  
   
• Education: Degrees, diplomas, and certified skills

FAQs

1. Is zkPass safe to use with sensitive data?

Yes. zkPass never uploads or stores your private data. All zero-knowledge proof computations are done locally on your device.

2. Can I use zkPass with any website?

zkPass is compatible with all HTTPS websites, making it highly accessible without the need for API integrations or special permissions.

3. What kind of applications can benefit from zkPass?

zkPass can be used in decentralized identity systems, DeFi lending, AI data verification, and any application requiring verifiable credentials with strong privacy guarantees.
