Prove you made it first.

Upload a file. Get an immutable, timestamped proof on the blockchain.
The file never leaves your device. Only the hash goes on-chain.

The Problem

AI-generated content is getting indistinguishable from the real thing. Deepfakes, synthetic writing, AI art — anyone can produce anything and claim they made it first. There's no reliable way to prove when a piece of original work existed.

Origynl fixes this. SHA-256 hash your file, record it on Polygon, and the blockchain timestamp becomes your evidence. It's not DRM. It's a notary.

How It Works

Certify Upload an image or PDF. Origynl computes a SHA-256 hash and writes it to the OrigynlLedger smart contract on Polygon. The file stays on your device.

Verify Drop in any document to check if it's been certified. If the hash exists on-chain, you get the timestamp and transaction record.

Capture Take a live photo with embedded GPS, timestamp, and device metadata. Creates a "witness proof" tied to a blockchain-anchored hash.

Watermark Certified images receive a visible watermark and embedded metadata proving certification status.

Try It

Live at origynl.vercel.app — certify a file in under 30 seconds.

Or run locally:

git clone https://github.com/foolish-bandit/Origynl.git
cd Origynl
npm install
npm run dev

Blockchain writes require Vercel serverless functions. Local dev renders the UI but on-chain transactions need deployment. See setup below.

Use Cases

• Artists & photographers — timestamp your original work before publishing
• Journalists — create verifiable witness proofs with embedded location/time
• Researchers — prove when a dataset, paper, or finding was produced
• Legal — establish prior art or document existence at a specific time
• Developers — certify code snapshots, audit trails, or build artifacts
• Anyone — prove "I had this file at this time" with cryptographic certainty

Tech Stack

Layer	Tech
Frontend	React 19, TypeScript, Tailwind CSS
Build	Vite 6

Smart Contract

Deployed on Polygon Amoy at 0x894C...9d41

The contract is simple by design: store a SHA-256 hash, record the sender and timestamp, emit an event. Immutable once written. See BLOCKCHAIN_INTEGRATION.md for contract architecture.

Deploy

Prerequisites

• Node.js v18+
• A Polygon wallet with testnet POL (faucet)

Vercel (recommended)

1. Fork this repo
2. Import into Vercel
3. Add environment variables:
   • PRIVATE_KEY — your Polygon wallet private key
   • CONTRACT_ADDRESS — 0x894C98bf09B4e9e4FEd3612803920b7d82C59d41
4. Deploy

Local Development

git clone https://github.com/foolish-bandit/Origynl.git
cd Origynl
npm install
cp .env.example .env.local
# Edit .env.local with your PRIVATE_KEY and CONTRACT_ADDRESS
npm run dev

---

Roadmap

• Polygon mainnet deployment
• Batch certification via Merkle tree (V2 contract)
• WalletConnect self-custody mode (sign with your own wallet)
• C2PA Content Credentials for captured images
• PAdES-signed certificate PDFs
• OpenTimestamps dual anchor (Bitcoin + Polygon)
• Perceptual hash + steganographic watermark
• Public shareable /proof/:id verification page
• IPFS pinning for certified file backup
• PWA / offline capture with queued certification
• Mobile-native capture (Capacitor)

Explicit non-goal: Origynl does not and will not use AI for authenticity scoring. Provenance is established cryptographically, not inferred.
