ProofNote AI turns source documents into structured AI reports, stores source/report files on 0G Storage, and records proof hashes on 0G Chain for tamper-resistant verification.
ProofNote AI is a verifiable AI report generator built on 0G.
The project solves a common problem in AI-generated content: users can quickly generate reports, summaries, contract reviews, or research notes with AI, but it is difficult to prove what source document was used, whether the report was modified later, and when the result was created.
ProofNote AI provides a simple verification workflow:
1. The user uploads a source document.
2. The application generates a structured AI report, including a summary, key points, risk analysis, and conclusion.
3. The original source file and the generated report are uploaded to 0G Storage.
4. The returned source root hash and report root hash are recorded on 0G Chain through the ProofNoteRegistry smart contract.
5. The user can later verify the report through the verification page and the 0G Explorer.
This creates a tamper-resistant proof layer for AI-generated documents. It can be used for AI research reports, contract review summaries, due diligence notes, meeting records, academic notes, DAO proposals, and any document workflow where traceability and verification are important.
The current MVP includes wallet connection, AI report generation, 0G Storage upload, on-chain proof recording, 0G Explorer verification, and a verification page that reads report records from the smart contract.
During this hackathon, we completed the full MVP workflow for ProofNote AI.
Completed features include:
1. Built the frontend application with a clean document upload and report generation flow.
2. Implemented structured AI report generation based on uploaded source documents.
3. Integrated 0G Storage to upload both the source document and the generated AI report.
4. Implemented the ProofNoteRegistry smart contract to record source root hash, report root hash, metadata hash, owner address, and timestamp.
5. Deployed and tested the smart contract on 0G Chain.
6. Added transaction feedback and 0G Explorer links so users can verify on-chain activity.
7. Built a verification page that reads report records from the smart contract.
8. Prepared a demo video, GitHub repository, README documentation, and project submission materials.
The MVP demonstrates an end-to-end verifiable AI report workflow: source document → AI report → 0G Storage → 0G Chain → verification.
