What is the longest used firstbits? How could I find out? I think it would be two vanity addresses with the same prefix, yes? Anything longer than about seven characters for a firstbits would require a lot of computation.

  • No easy way to find the shortest, so it's not clear why you expect there was an easy way to find the longest, instead.

  • @Lohoris The largest problem is that if you say "the longest firstbits is 1aaaaaaaaaaa" then somebody with vanitygen will just try to make two vanity addresses that have more characters in common.

  • @NickODell: Unless the longest firstbits is already so long that finding a longer one will be computationally prohibitive.

  • Finding the shortest one unused is rather different than finding the longest one used, IMO.

    It is valid (see uncaptcha.net/bitcoin.php ), but I think nobody has the private key... Chance to choice valid address is 1 : 4 billions which is no computational problem...

I think I found the one with the longest firstbits http://blockchain.info/fb/1234567891234567891234567891w
