Equally (or more) interesting to me is https://onename.io, which leverages the namecoin blockchain to distribute PGP key hashes. See, for example, https://www.onename.io/wyager

You have, among other things, my key hash and a link to get my full pubkey. This is all stored in the publicly accessible and cryptographically authenticated Namecoin blockchain. This has some advantages over centralized and compromisable servers like pgp.mit.edu or keybase.io.
