>The same "problem" occurred when people invented GPU mining, then FPGA mining, then ASIC mining. As long as SHA256 isn't broken, it doesn't matter what kind of speedup miners manage to get This isn't a break of SHA256 obviously but it is a break of the PoW for Bitcoin. The whole point is that you have to hash the same amount of data for each attempt to find a block. ASICBOOST is about not having to hash the same amount of data. This isn't a speedup of the hashing algorithm, this is about avoiding needing to hash the same amount of data for every attempt. Call it an optimization if you want, but Bitcoin was designed with the goal that this wasn't possible.
