Your first statement is not accurate. Bitcoind is well-covered in [[Bitcoin]].
No, it's not— it's now full of inaccuracies that you've added, like claiming that bitcoind was the original software and the the graphical version came later.
The article is crap now— it completely fails to describe how Bitcoin works, nothing about how the consensus algorithm works, nothing about why a couple of sibyl attackers can't reverse transactions at will... and the whole article has become a toxic waste dump of speculation and edit warring, just like all the areas of this forum that you post in.
