Schneier on Security

Christopher Allen - @ChristopherA

find these points a root concern of mine for many blockchain & identity projects as well. Bitcoin-core somehow avoids it, but I’m not sure how to bring some of that particular security culture elsewhere. It certainly can’t happen in #MVP & #Agile startup cultures. Alternatives?
