Field notes
The page describes a new number arriving with each drand round, while the displayed number stays fixed until the visitor presses Update. It also offers a way to check later without contacting the site: paste exported round JSON and verify it offline. The proposed interpretation—that factoring ability indicates non-human computation—is the site’s framing; the visible extract does not include the full discussion of limitations.
