ktimesg, did you see the partial match found late last night/early this morn: 19vkiEajfhu8gnX5QUJZReqALvkTncJtgu
Is it the most nearest address found (in the term of hash160 matching) so far?
No, it's not. It's only 56 bits.
Closest one he has is
19vkiEajfhv74c3uqEVjvCTagKpaz7TgHH
which is 58 bits.
If that doesn't make sense to you because the base58 prefix is longer... what can I say, longer base58 prefixes don't mean a better actual prefix match, due to how the numerical ranges overlap more or less with the binary ranges, since the bits are the tundamental unit of counting quantity of information, not monkey emojis / b58 digits.
