>> A blockchain-based solution to what, though?
To the declining popularity of Jabber, to put it short.
As an additional benefit, blockchain is indeed more secure to run than an ejabberd instance.
I understand your irony with "Hype Juice" etc. But in the end, good software is that which people use, right?
Though I will concede your point slightly; if XMPP needs some more Hype Juice to win, I can't deny "but on a blockchain!" could help there. Kinda not being sarcastic here.
