Vouch, Delegate - The Identity Layer

Trust, Delegate, Block, Replace

There are four statement types involved in establishing and maintaining the identity layer. All are signed by one key and state something about another.

Trust: keys that meet the bar of "human, capable, and acting in good faith".
Block: keys that don't.
Replace: your own lost or compromised keys.
Delegate: disposable keys that you provide to services to allow them to act on your behalf (until you revoke them).

When you vouch for someone else by scanning their ONE-OF-US.NET's phone app (or a QR code they shared with you), the ONE-OF-US.NET phone app uses your private key to sign and publish a structured statement that references their identity key, names them, and affirms that they're "human, capable, and acting in good faith".

(Still vapid; we don't know whose key that is.)
