:) - that's one approach.

That's also a non-starter for most anyone that wants a long-lived
identifier. Accidents happen. Crypto is broken. You don't want to tie
your identity to some mathematical thing that happens to be secure today
but may be gone or compromised tomorrow.

The current approach for the WebDHT is to loosely couple identifiers and
the keys that you can use to prove that those identifiers are yours.

For example, the WebDHT enables you to specify a set of keys or other
identifiers that should have write access to the entry in the DHT. This
means that even in the event of a key loss, you can recover that
identifier by asking people (or services) that you trust to associate a
new device/keypair with the identifier.
