Why Choose This Project?

Traditional notarization processes are manual, time-consuming, and prone to forgery or disputes. This blockchain-based document notarization and timestamping app enables secure, verifiable, and tamper-proof document validation. By storing hashes of documents on blockchain, it provides proof of existence, integrity, and timestamping, eliminating the need for intermediaries.

Working Flow

User Connects Wallet / Logs In
→ Login as User or Admin via MetaMask
Document Upload & Hashing
→ User uploads document
→ System generates a unique cryptographic hash
Timestamping on Blockchain
→ Hash stored immutably on blockchain with timestamp via smart contract
Document Verification
→ Anyone with the document can hash it and compare with blockchain record
→ Confirms integrity and timestamp of submission
Dashboard Updates
→ Users and admins monitor uploaded documents, verification results, and timestamps
Audit & Transparency
→ All notarized documents and verification records are tamper-proof and auditable on blockchain
