How to verify
- Save the article element (
<article id="lc-piece">) exactly as served on the piece page. - Hash it with SHA-256 and compare the result with the published HTML hash on this page.
- The .ots proof, once submitted, is checked against the OpenTimestamps calendars and then Bitcoin.
- A match shows the text existed then. It does not show the text was right.
