Is 1 week at 100% CPU right? Any parameters sound painful at such durations. Is this for revoking once you lost the key or something? I though PoW only exists here because you broadcast? Or is that 1 week as a very backgrounded task? As an aside, there is a verifiable delay function (VDF) project by the ethereum foundation, which protect against parallelism. I’d expect VDFs provide less protection against ASICs per se than Argon2, but they should ideally provide relatively high confidence in ASIC speed. VDFs should only consume one core while running, which might improve user experience. We can chat about this once some VDF achieves the desired confidence in ASIC speed. ;) Jeff
