  • Hash on your device. Only the hash is sent.
  • Pending until a real Bitcoin height.
  • A receipt proves those bytes existed by that height. It does not prove the contents are true.
  • Anyone can check at /verify with no account.
  • For a composed object, keep the object file; without it the parts cannot be displayed.
The parts list is not uploaded.

The phone hashes it. You get a receipt. A height means these exact bytes existed by that block.

One file: the line you type, the file name, any place, the thread and Open after go with the hash so the receipt page can show them. Open after is a note, not a lock. In Several files and a line, only the hash is sent.

Anyone with the link can open this.

You get a receipt page you can send and a proof file to keep.

Download the proof file again once the receipt shows a Bitcoin height.
