Bitcoin mining network vulnerability 'not a big deal'
A paper released yesterday by researchers Ittay Eyal and Emin Gun Sirer at Cornell University suggested a subtle new way in which the bitcoin mining network could be vulnerable to a form of economic attack called 'Selfish Mining'.

Assuming you haven't already heard of a paper released by two researchers at Cornell University yesterday that suggested the Bitcoin currency is susceptible to a little something called 'selfish mining,' I will do my best to give you the Spark Notes version.
