zk-Consent: DNA Protocol’s Privacy-Preserving Consent Architecture for Genomic Data Sharing

As personal genomic data becomes increasingly valuable in research, diagnostics, and digital identity, DNA Protocol introduces a powerful solution to a long-standing challenge: how to share DNA-based consent without compromising privacy.

Enter zk-Consent—a system developed by DNA Protocol that enables users to verify consent using zero-knowledge proofs (zk-proofs). This means participants can prove they have agreed to share their DNA data for a specific use—without ever revealing the data itself.


zk-Consent is a consent verification framework that leverages zero-knowledge cryptography. It allows individuals to provide cryptographic proof that they’ve granted access to their genomic data or identity, while keeping the data confidential.

Key Components:

  • zk-Proof Generation: Creates a cryptographic proof of consent tied to a user’s DNA hash.
  • Verifier Interface: Allows researchers or institutions to confirm the existence and validity of that consent.
  • Immutable Audit Trail: All consent proofs are timestamped and recorded on-chain for full traceability.

🛡️ Privacy by Design

The zk-Consent system is built with strict adherence to privacy-first principles:

  • No raw DNA is revealed
    Only a mathematical proof tied to a DNA hash is shared.
  • Revocable consent
    Users retain the ability to withdraw or update their consent through their on-chain identity key.
  • Tamper-proof history
    Every zk-consent transaction is immutably recorded, creating a transparent, verifiable audit log.

⚙️ How It Works

  1. User anchors their DNA hash via GenomeChain™
    This hash is unique, irreversible, and anchored to the blockchain.
  2. User signs a consent request with zk-Consent module
    This could be for research participation, clinical access, or KYC validation.
  3. A zero-knowledge proof is generated
    It confirms the individual’s consent without disclosing identity or raw genetic data.
  4. Verifier receives proof and verifies on-chain
    If valid, access to relevant services or records is granted.

🔗 Integration in the DNA Protocol Ecosystem

zk-Consent functions as a cross-module privacy layer and is interoperable with:

  • Bio-KYC: Adds cryptographic consent to identity verification workflows
  • GenomeChain™: Anchors consent to immutable genomic ownership
  • Health dApps: Allows on-chain consent for clinical trials or data sharing without exposing sensitive information

🌐 Blockchain Infrastructure

While zk-Consent is blockchain-agnostic, DNA Protocol has designed it for optimized performance on XRP Ledger (XRPL) infrastructure due to its low transaction cost and fast settlement capabilities. This ensures zk-Consent proofs can be processed efficiently and globally.


✅ Current Status

  • zk-Consent is an active component of DNA Protocol’s architecture.
  • No personal data or DNA sequences are stored on-chain.
  • All zk-proofs are user-generated and cryptographically signed.
  • Designed to support privacy regulations such as GDPR and HIPAA compliance models.

Conclusion:
With zk-Consent, DNA Protocol empowers individuals to participate in genomic data ecosystems—securely, privately, and transparently. It’s a cornerstone of a future where digital health and privacy can coexist without compromise.
