Cryptocurrency insecurity: IOTA, BCash, and too many more80.99

Cryptocurrencies: a weird agglomerate of fascinating technology built by brilliant engineers; a whole new and potentially important form of economics; … and hype-machine puffed-up crazy-talk nonsense. So, as you might expect, they also combine state-of-the art resilient engineering and comical clown-car so-called security. Yes, that’s right — I want to talk about IOTA, and (to an extent) Bitcoin Cash.

Modern security practices include: an understanding of and commitment to responsible disclosure; making yourself available and accessible to third-party security researchers; offering bug bounties; fuzzing your code; etcetera. They also include valuable truisms such as “don’t roll your own crypto.” Here that’s crypto as in cryptography, and it means, always always always use tried and time-tested cryptographic algorithms and implementations. Do not try to build your own from scratch. You will regret it.
