[Bitcoin-ml] Community survey on new Bitcoin Cash address format

Couple of comments on assumptions implicit in your questions.

I think it's important to view this question in the context of the
fact that the existing format and all proposed formats have at worst a
one-in-a-billion probability of accepting an invalid address.

None of the formats are proposing error correction as far as I'm
aware.  Although Bose-Chaudhuri-Hocquenghem codes are capable of error
correction, I'm not sure anyone is proposing they are used for such a
purpose.  Certainly BIP173 says this should *not* be done, due to the
risks of a user accepting a bad suggested correction.

base58 is already used to encode data longer than 160 bits
(e.g. private keys, xpubs and xprvs).  base58 has no intrinsic limit
to data length.
