About
The problem it solves Problems Solved Individuals and MSMEs often need proof that a document: ✅ Existed at a certain time (timestamp) ✅ Has never been modified (integrity) ✅ Can be verified independently (without intermediaries) Traditional solutions such as conventional notaries: ❌ Expensive ❌ Centralized (dependent on one party) ❌ Administratively complex ❌ Unaffordable for small businesses, freelancers, or students Solution: ProofStamp ProofStamp offers a simple way to stamp your documents on the blockchain: Upload your document (PDF, image, or other file) The cryptographic hash is calculated automatically (Keccak-256) Stamp the hash onto the blockchain with one click Verify anytime by re-uploading the same document 🔑 Key Principle: Blockchain is only used as a trust layer (permanent neutral clock), not as a database. All logic and UX remain off-chain.
