A derogatory word for someone who is not technical, yet wants to talk to you about "blockchain" and related technologies ad nauseam, usually as a tactic to sound smart and relevant.
Blocktards seem to think that blockchain technology has a role in every facet of humanity, and will often cite that they know people that are working on a new cryptocurrency that is a "game changer".
I asked the blocktard at the dinner party to pass the salt, he said it might take 2 to 3 weeks to process the transaction.
Someone who never stops talking about the stupidest shit. Somebody that you wish you could just knock some sense into and tell them to stop being a dumbass.
