Dev here: Keytrace lets you verify other accounts like Keybase does (e.g. public proofs of identity) but doesn't orient the connection on GPG. Instead uses an atproto/bluesky account as the central source of identity, and stores everything in atproto.
So you could think of it as a simpler, de-centralized version of the Keybase identity proof system.
