NSA Strategy 2012-16: Outsourcing Compliance to Algorithms, and What to Do About It
Over the weekend, two new NSA documents revealed a confident NSA SIGINT strategy for the coming years and a vast increase of NSA-malware infected networks across the globe.

Game Theory and Bitcoin
In light of the back-and-forth about the recent Eyal and Sirer (“ES”) paper about Bitcoin mining, I want to take a step back and talk about what a careful analysis of Bitcoin mining dynamics would look like. (Here are some previous posts if you need backstory: 1 2 3 4 5.) The key to a…

Why the Cornell paper on Bitcoin mining is important
Joint post with Andrew Miller, University of Maryland. Bitcoin is broken, claims a new paper by Cornell researchers Ittay Eyal and Emin Gun Sirer. No it isn’t, respond Bitcoiners. Yes it is, say the authors. Our own Ed Felten weighed in with a detailed analysis, refuting the paper’s claim that a coalition of…
