A Guide to 99% Fault Tolerant Consensus

Special thanks to Emin Gun Sirer for review We’ve heard for a long time that it’s possible to achieve consensus with 50% fault tolerance in a synchronous network where messages broadcasted by any honest node are guaranteed to be received by all other honest nodes within some known time period (if an attacker has more than 50%, they can perform a “51% attack”, and there’s an analogue of this for any algorithm of this type). дальше »

A survey of 306 infosec professionals at London’s Infosecurity Conference 2008 from Lastline showed that 45 percent commit one of the biggest security cardinal sins — reusing passwords across accounts. дальше »

As his Hungarian parents had fled post-war Soviet regime to settle in the United States, Nick Szabo came to call the Californian Bay area of the 1990s his home. Here, he was among the first to frequent the in-person “Cypherpunk” meetings organized by Timothy May, Eric Hughes and other founding members of the collective of cryptographers, programmers and privacy activists centered around the ’90s mailing list of the same name. дальше »
