I love this bit from the article (emphasis mine):
Which is bullshit, unfortunately.Quote
Now we have a small piece of pure, incorruptible mathematics enshrined in computer code that will allow people to solve the thorniest problems without reference to “the authorities”.
There is no mathematical proof that the mining problem is hard, or that it is hard to get the private key of any given address.
No one has found how to do either of those things efficiently yet, but a smart teenager may find one tomorrow. Or may have found it already.
But bitcoiners need not worry, if that happens not only bitcoin, but all current e-commerce protocols will be compromised...
Oh for goodness' sake, Jorge. Do you have any understanding of the maths behind this, or how long it would take to implement a vulnerability in a useful way? Either you do, in which case this is pure and simple trolling. Or else you don't, which also raises plenty of questions. In either case I hope none of your students stumble across this thread.
i think he has finally lost the plot

I actually checked carefully several times to make sure this really was JorgeStolfi, not JorgeStofli. I'm still wondering whether someone else wrote it.
This simply isn't becoming of a respectable academic, Jorge.
