Thanks to Thomas Voegtlin for creating the Electrum software and infrastructure and for maintaining it so diligently. Electrum is probably the best desktop Bitcoin wallet solution for most users. My faith in it is such that I use Electrum software to store most of my Bitcoins. Whilst the vast majority of the code here is my own original work and includes some new ideas, it is very clear that the general structure and concept are those of Electrum. Some parts of the code and ideas of Electrum, some of which it itself took from other projects such as Abe and pywallet, remain. Thanks to the authors of all the software this is derived from. Thanks to Daniel Bernstein for daemontools and other software, and to Matthew Dillon for DragonFlyBSD. They are both deeply inspirational people. And of course, thanks to Satoshi for the wonderful creation that is Bitcoin.
