Landing page captured for the 2026-09-23 issue.
For
People using BitNames for signed messages and payments
Worth noticing
The download page says builds lack code-signing certificates and explains how to build from source or override operating-system warnings.

Field notes

The page walks through a signature check in which a message claiming to be from Alice is rejected because it does not match the key her name publishes. Its chat example shows direct messaging without a relay, while a separate example puts a 5,000-sat price on a stranger's first message. The project says checks run against the user's own node; the supplied page evidence does not independently verify that claim.
