Market Heatmap
DAS timestamp — your files' fingerprint on the XRP Ledger
Your browser calculates the file's SHA-256 fingerprint, and it goes into a public XRP Ledger transaction. Later anyone can check that exactly this file existed by a certain time at the latest. The file never leaves your device.
- Sound Proof — for songs: master, lyrics, stems · $9 one-time · Pro $29/year
- Estate Proof — for property files: offer, listing, condition photo · $1 per file
- Verification: free, for anyone
A timestamp shows when a file existed. It is not a copyright registration or a notarial act.
