Somewhat relevant to this discussion is Zooko's triangle:

There's also the Urbit ID system, where you essentially
purchase small integer IDs on the Ethereum blockchain,
thereby verifiably connecting your (long, 256-bit) public
key with your (short, 32-bit) integer ID. Effectively,
they're akin to static IPv4 addresses but with associated
public keys, where the mapping between IDs and public keys
is stored on the blockchain.

They also have a mechanism for systematically converting
integer identifiers into pronounceable strings. For example,
uint32_t 1000000000 corresponds to the name ~tabfep-rovsen.
