Hey PH! π
I built ETN DataProof to solve a real problem β 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 β especially from anyone working on AI datasets or EU AI Act compliance!
