I would not be concerned about this. The way the asics operate is they discard the results. Also, the hashes are random strings which don't compress very well, so storing trillions upon trillions of them (for later analysis) is not practical.
- WorldMaker 4y agoAgain, the point of the fear is not the specifics of current operations (ASIC details; which y'all are talking about as if all of the miners are using the same hardware), but the fear of future operations and that there's an enormous industrial preimage attack effort at all. One that we can see in real time, in global energy consumption graphs. Maybe you find "cold comfort" that because we can watch it in real time if someone discovers a weakness we will also watch its repercussions and the subsequent horrifying fall in real time, too, but I certainly don't.
