Dudes. Blockchain.
Forgive me, I'm laowai so I speak English only. I know, but don't much care, what a Blockchain is. But what in Ada's name is a 'Dude'? It looks like a typo: should it not be 'Dud' ? If not, how is it pronounced? 'Dudee' ? It's used here in The Register, so it must be an IT term of some sort - with an obscure origin, like 'byte', perhaps. Somebody explain why I should understand and use this word in my work.
