Hey PH! 👋 I built ETN DataProof to solve a real problem — proving that your data existed at a specific point in time, without uploading it anywhere. The file never leaves your device. Only its SHA-256 hash goes on-chain. For less than $0.0001. Would love to hear your thoughts — especially from anyone working on AI datasets or EU AI Act compliance!
