What do you ( #fediverse ) think of a social networking done on (via) the #blockchain ?
Are there working proof of concept implementations?

Since @silverpill already working on PKI\cryptography for fediverse, blockchain seems like a next evolutionary step for social networking, since it's just distributed (cryptographic) database.

I'm sorry that I lack resources & haven't put enough effort researching #crypto, #freenet , #hyphanet . But it seems to me kinda on topic, So I want to hear from people.
Maybe I want to hear from people like @ArneBab & @silverpill
I don't know here anyone else who work on #p2p social networking.
