PrivChain

Secure, verifiable, and decentralized credentials on the blockchain. Empowering issuers and holders with Zero-Knowledge Proof (ZKP) privacy principles.

Why PrivChain?

Built for the future of digital identity. Verification without compromise.

Tamper-Proof

Credentials are anchored on-chain with cryptographic proofs. Impossible to forge or alter once issued.

Zero-Knowledge Privacy

Prove eligibility (e.g., Age 18+) without revealing personal data. Mathematical truth, absolute privacy.

Decentralized Storage

Credential files are stored on IPFS, ensuring redundancy, availability, and censorship resistance.

Streamlined Workflow

01

Issuer Connects

Authorized organizations connect their wallet to the PrivChain admin panel.

02

Credential Issuance

The issuer uploads a certificate, fills in metadata, and signs the transaction.

03

ZKP Generation

Holder generates a proof locally to verify claims without sharing sensitive details.

04

Holder Verifies

The recipient receives the credential instantly in their dashboard, verifiable by anyone with the link.

Verified Credential

Issued on Ethereum (Localhost)

Traditional vs. ZK Verification

Traditional Identity

  • Reveals full ID document & birthdate
  • Data stored on vulnerable central servers
  • High risk of identity theft & leakage

PrivChain ZK Proofs

  • Reveals ONLY validity (e.g. 18+)
  • Data stays on your device (Client-Side)
  • Mathematically proven privacy & security
