- Mention the reason for the long validation time is the verification of transactions. We previously implied it was download time, but some people have really fast internet. - Better describe bitcoind cookie authentication and provide an example to make it even more clear. - Add a link to bitcoin-s - Make the long sidebar on collision attacks even longer by descripting a pre-image attack in addition to the previous descriptions of second pre-image and collision. That way we don't conflate pre-image and second pre-image. - Remove redundant tip box about an oddity in language about compressed and uncompressed private keys. - Link to information about vanity address "mining" (brute forcing)
