So this is like a decentralized keybase? Are the identities and associated public keys stored in a decentralized manner? It wasn't clear to me when I registered an identity, because I figured if it's decentralized, then I would have to pay for it in some manner with a cryptotoken. I always thought this would be a good use case for Ethereum (and indeed, there seem to be a few projects working on it). It would be extra cool if it could integrate into existing wallet/dapp software so you don't need to juggle extra keys. Anyway, cool stuff. I'm hoping more people adopt end to end encryption

edit* looks like the identities are stored in a decentralized manner, and that all of this should integrate with blockstack's keychain and browser
