Data Seal - Verifiable Data Integrity
FHE-encrypted tamper-proof document sealing with three seal modes.
Implements: PIP-0010 / LP-0535
Seal Modes
| Mode | Description | Use Case |
|---|---|---|
| Public | Transparent, anyone verifies | Journalism, open records |
| ZK | Content hidden, properties provable | Trade secrets, proprietary models |
| Private | FHE-encrypted, selective disclosure | Whistleblower evidence, medical records |
How It Works
- Seal: Hash your document, encrypt an integrity tag with FHE, store on-chain
- Verify: Submit an encrypted challenge tag — homomorphic comparison reveals match/mismatch without exposing the original tag
- Batch: Seal thousands of documents in one transaction
Quick Start
npm install
npx hardhat compile
npx hardhat test
# Deploy
npx hardhat task:deploy-seal
# Create a seal
npx hardhat task:seal --contract <address> --hash 0xabc...
# Verify a seal
npx hardhat task:verify-seal --contract <address> --id 0 --tag 42
# Batch seal
npx hardhat task:batch-seal --contract <address> --count 10
