Exactly - knowledge of the English language isn't a binary. Equally, I don't remember ever learning names of special characters in French class back in elementary school, but I do recall us drilling the alphabet and especially numbers repeatedly. If I were trying to tell a French speaker a BTC address, I'd probably be ab= le to succesfully do it with bech32, but not with any encoding using special characters. > In general: >=20 > In the past weeks people have contributed two new reference implementatio= ns > (Haskell and Rust), and a C++ and Go one are underway (see > https://github.com/sipa/bech32). FWIW, I also did a partial rust implementation of just the Bech32 encoding = for a prototype non-BTC use-case. Other than the version number being it's own "chunk" I found it very straight-forward to implement and I think it'll make for a nice replacement for what otherwise would have been hex digests. --=20 https://petertodd.org 'peter'[:-1]@petertodd.org --wRRV7LY7NUeQGEoC Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQEcBAEBCAAGBQJZD6D0AAoJECSBQD2l8JH7TrAH/j1qGrouE1xadWSyHR3yraN3 3tMfNMMnp3VnB3KTmz9u4Dv4ku4g7OW5vPLYlFKeUPnB2VAMkNPHrc2QWRYnNzeQ fhVi4ue0BrPf7vaYB6icq7gW9zLraC7p4/qBbeK6ZFOGa2N+PHHfTRveWpT04ThH tC97avRgiNM1JCGGy+I7oaKca6RNLuchPCW7OoFouV6h+qc+bztE5vt8aN0pQuUd 7Km7vgLIqK/Mq0GVPkZQqPlsWE6jXJnmWkbqrgIDQN6IM+YsVSiCKFCZhg/x8awZ 5SygIvRWL02GqoFnJidSRVQmA6Xwl1Ylr05CiU3azjqVKxmoEQeUOV3c/HskJWw= =+BN2 -----END PGP SIGNATURE----- --wRRV7LY7NUeQGEoC--
