Ask HN: Twitter on Blockchain?

In the light of latest events what are your thoughts about the idea of a de-centralized social network? Absence of central authority => noone can be blocked, suspended or censored in any way whatsoever.

DISCLAIMER: I'm not a Trump supporter, godforbid. I actually agree that banning him was a necessary thing given the damage his tweets caused.

Just interested to learn what people think from a general perspective of freedom of speech.
