The above makes for a great homework problem for budding cryptographers: Why did the three forms of signature, DKIM, long-lived bitcoin address, and Official Swiss Government Identity fail to let you actually verify you have the right code? (but make for great security theater) Bonus question: Who has the smallest work-factor for such an attack? Two rewards of 25mBTC for correct responses to each question from a crypto newbie. > Thanks to Mike Belshe, the wallet can now send to P2SH addresses.
