ProofChain
Verify documents with confidence.
A full-stack platform for issuing verifiable certificates and checking document authenticity using blockchain-backed proofs.
Visual concept illustration. This is a planned MVP, not a deployed client product.
The challenge
Why it matters.
Organizations need a simple way for people to check whether a document is authentic. ProofChain explores cryptographic verification without publishing private documents on a blockchain.
Planned MVP
What the first version will do.
- 01Let approved issuers upload or register a digital certificate.
- 02Generate a cryptographic document fingerprint and anchor its proof on a testnet.
- 03Provide public verification by comparing a submitted document with the registered proof.
- 04Support proof revocation and a transparent verification status, without storing document contents on-chain.
Technical approach
How it's designed to work.
Experience
React and TypeScript issuer and public verification screens.
Application
FastAPI for identity, authorization and SHA-256 document hashing.
Blockchain
Solidity contract on a Polygon testnet for registering and revoking hashes.
Storage
PostgreSQL for off-chain metadata and issuer records.
