      1/ I've been reading with pleasure @saifedan's book "The Bitcoin standard" that I recommend to anyone interested in #bitcoin, but in particular to economists, and to @paulkrugman and @JosephEStiglitz. First time ever I read something accurate about #bitcoin from an economist!pic.twitter.com/XFwLL5Ew4j

      2/ Most of @saifedan's book is a about monetary theory. I also consider necessary to review classical monetary theory in order to properly understand #bitcoin. I took the same approach in my survey "Bitcoin and decentralized trust protocols" https://www.ems-ph.org/journals/newsletter/pdf/2016-06-100.pdf … … (p.32)pic.twitter.com/qH0xB2d1zU

      3/ I particularly liked the highlight of the property of money as information tool (see chapter 6) that is missing in my survey. I would have liked more insistence on the useless property of money to be good money, and on the new programmable property of cryptocurrencies.

      4/ I found too harsh and misplaced the criticism of Keynes as economist and person. Keynes was in origin a probabilist and has a very interesting book on probability, which takes a different point of view from Kolmogorov's on which modern probability theory is based.

      5/ I do agree with the criticism of #Keynesian monetary policies, but many times #Keynes ideas have been distorted and extrapolated without considering the actual situation in his living time. Thumbs up for exposing the miserable academic situation of #economics.

      6/ On a few technical points there are some inaccuracies that can be easily corrected. Chapter 8: When we ECDSA sign a message we don't hash. Chapter 10: Breaking SHA-256 as described is not possible.

      7/ There is some confusion about 51% attack and double spend. Someone with 51% hashpower can double spend, but the converse is not true. Also there are many forms of 51% attacks.

          Hi Hugo, just looking at the paper quickly I do agree pretty much with your review. When I got more time I will read it more carefully..,but, frankly, I am a bit fed up with all this non-sensical papers by economists that don't know the basics of the technology.

          You & @CGrunspan might find it interesting as it mentions selfish mining. Besides stating that PoW is "economically limiting" based on a faulty model, it also states that PoS research is "interesting". There seems to be an academic circle that self-references & reinforces bias.

          Does advocating against PoW must propose a working alternative solution to Nakamoto's Byzantine Generals problem...I haven't seen any so far...
