The funny thing is that FLOPS means
floating point operations (per second) and SHA256 computations (the core Bitcoin hashing algorithm) take exactly
0 (zero) floating point ops as they consist of integer and bitwise ops only. Besides floating point operations are usually slower than integer and logical ones.
Bottom line is - measuring Bitcoin performance in FLOPS is wrong!

Sure, measuring
bitcoin hashing performance in flops is wrong, but what we want to know is what the flops of the computers in the bitcoin network
would be if they were doing something that required floating point operations? Maybe there's just no way to know, but that's the question, I think.
