Makes me think of
namecoin Namecoin (sign: ℕ; code: NMC) is a cryptocurrency which also acts as an alternative, decentralized DNS, which would avoid domain name censorship by making a new top level domain outside of ICANN control, and in turn, make internet censorship much more difficult, as well as reduce outages
Unfortunately Namecoin is used more for trading than it's original purpose. Maybe we should consider some hybrid namecoin/public-root DNS in this case
