SOULINTIME · BITCOIN TIME

Bitcoin is the clock.

We date bytes to it.

  • 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.

Write a line or pick a file. The phone hashes it. Bitcoin is asked to date that hash. You get a page you can send. Pending = not in a block yet. A height = these exact bytes existed by that block. It does not mean the words are true.

Prove this exact file existed before a certain date, without uploading it.

For example: date a contract draft today. If anyone later asks when that draft existed, the same file and its receipt show it existed by that block. See the receipts others have dated in Firsts.

A person, a firm, or an agent can check without an account.

Grey means pending: the proof file exists, no height yet. Orange means In block N: these exact bytes existed by that block, not a claim the words are true.
