Hey Product Hunt! 👋 I'm Anthony, I built Aluchin solo. The problem: proving a document existed at a specific time and hasn't been tampered with costs $25+ through traditional notarization. Aluchin does it for less than a penny in 5 seconds. Upload any file, we SHA-256 hash it and record the hash on Hedera's public ledger. Your document never touches our servers — we only store the hash. Stack: Node.js, Express, SQLite, Hedera SDK, Stripe. 52 automated tests. Full REST API. Try it free (no signup): https://aluchin.com API docs: https://aluchin.com/docs Would love your feedback — what would make this more useful for you?
