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. This does 2 things:

Trust: keys you vouch for as representing someone "human, capable, and acting in good faith"
Block: keys you've identified that should not be trusted
Replace: lost or compromised identity keys you used to use
Delegate: keys that represent you on various services (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 know that the key being trusted has not been tampered with, but we don't know whose key signed this statement.)
