A 283 bit ECC key would
provide the same security as a 3,072 bit RSA key, and that would be more than enough for a safe p2p identity. 283 bits would fit to 36 bytes. Doesn’t sound too big to me.

In the first place there is only one peer that you can trust to authenticate anything, and that is you yourself. You can search identities through other peers but it is up to you to check that they are the ones they claim to be.

Why would my contacts forget my identity when I go offline? They have my permanent public key stored on their computers. Whenever I pop back online, I can search them by their public keys and after finding them I can prove my identity to them.
