Blockchain incorporated Flamethrower.

Elon Musk recently tweeted about making a $500 flamethrower that seemed something made out of a Sci-Fi movie.

Elon Musk is getting into blockchain, apparently. The tech entrepreneur announced on Sunday that his Boring Company tunnel-digging venture would start selling a $500 flamethrower to fund its upcoming projects. Limited to just 20,000 units, pre-orders skyrocketed in no time. Musk wasn't done yet, though.

"But wait, there’s more: the flamethrower is sentient, its safe word is “cryptocurrency” and it comes with a free blockchain,” he told his 18.5 million Twitter followers.

Tho it is very unlikely that Musk is actually going to build up a blockchain into his flamethrower. The fact he provided no detail on how the blockchain would benefit the product, alongside his sudden claim the flamethrower would be sentient, suggests it’s more likely a tongue-in-cheek reference to the cryptocurrency rush.

It not the first time Musk has linked himself to Bitcoin, though. In 2014, he dropped a tantalizing hint that he was the mastermind behind Bitcoin. This rumor took off in November 2017, after a former SpaceX intern published a Medium post claiming that Musk could well be Nakamoto.
