I'm surprised someone hasn't built what3words style translation algorithm for crypto. So instead of the user seeing an address as a long stream of character, it becomes a series of words.
Isn't that almost what those wallet seed phrases are? Or something very similar looking - that could introduce another new line of attack, where you think you're using an address and accidentally have your seed phrase.
That's for the private key, right? OP was talking about a smaller "fingerprint" for the public key that wouldn't necessarily be as long as a full seed phrase (or as secure)
