TimeProof - Prove it existed. Permanently.

TimeProof creates permanent blockchain timestamps for your documents, designs, and creative work. Upload a file or paste text we generate a SHA-256 hash and record it on Solana's blockchain in seconds. What makes it different: - Built for legal evidence, not crypto speculation - Designed around Australia's Evidence Act for court admissibility - No subscription pay per timestamp (from $0.50) - Instant verification anyone can confirm your proof existed

Hey Product Hunt I built TimeProof after watching too many freelancers lose disputes they should have won. The pattern is always the same: someone creates work, shares it with a client or collaborator, and months later there's a disagreement about who made what. The freelancer has files on their computer but no way to prove when they were created. Metadata can be edited. Emails can be questioned. Blockchain solves this elegantly write a cryptographic hash to a public ledger, and you have permanent, tamper-proof proof of existence. But most blockchain timestamp services are built for crypto people. I wanted something for normal professionals who just need evidence, not a wallet tutorial. So TimeProof is deliberately simple: - Upload file or paste text - We hash it and write to Solana (fast, cheap, permanent) - You get a PDF certificate citing Australian evidence law No subscriptions. No tokens. Just timestamps. Happy to answer any questions about the tech, the legal framing, or why I chose Solana over Bitcoin. Andrew
