Similar to how the SHA256 hash competition exists to validate a transaction, I wonder if this concept can be ported to addresses, so that the first few characters is significant to a human reader.
Is there value in making a public key address start with human readable text?
What approaches exist to accomplish this? Must the key pair be re-generated continuously or there there space to place a nonce?
Could this cause legal issues? ...such as a key that contains text matching censored information which is replicated to countries that ban that information
