I will now be signing commits using the PGP key found on this page:

http://libbitcoin.dyne.org/authors.html

(direct link: http://libbitcoin.dyne.org/keys/amir-taaki.asc.pgp )

I've also attached the same PGP key to this email. The key ID is 8C30AA9A

This is a good guide on making subkeys for other devs. I have my main
key, but under my main key, I've made a subkey then reuploaded to the
keyservers: https://wiki.debian.org/subkeys
