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.

Bitcoin isn't so broken after all

Wall Street software failure and a relationship to voting
An article in The Register explains what happened in the Aug 1 2012 Wall Street glitch that cost Knight Capital $440M, resulted in a $12M fine, nearly bankrupted Knight Capital (and forced them to merge with someone else).
