Solid post. Another viable direction to head in for our future decentralization of society. I am posting something in a half hour about reputation and honor, which relates to the identity and blockchain. The relevant part is:
"A public ledger of reputation, with a trustless identity, can be used to track and verify any claims against people, possibly categorizing them as "unfounded", "partially corroborated", and "conclusively verified", or something. This way abuse is mitigated by a requirement of evidence of some kind, in writing, picture, audio or video, with a variable weight of strength attributed to a piece of data or claim."
