If there are exploits, it's definitely going to be all Bitcoin and the like. Impossible for anything to compete against literally stolen, free CPU.

Interesting way to make crypto eco-friendly: acknowledge that even the most exploitative mining rigs can't economically compete against literal cpu-jacking at scale :)

CPUs cannot mine modern bitcoin in any capacity. Were at exahashes now.

Wait, is WebAssembly known to be insecure? This is news to me.

The latest Chrome exploit released in the past day used it.

There have been several PoCs of microarchitectural attacks, such as Rowhammer or Meltdown/ Spectre/ MDS, implemented in webassembly.
