Given the recent ACM article about faster-than-cpu persistent memory on the horizon, how does that affect memory-hard hashing algorithms?<p>A machine with a measly 256GB of memory can do around half a million Argon2 hashes simultaneously (using the Python library defaults for memory complexity of 512k), and that doesn&#x27;t include the memory built into high end GPUs, or what could be added to ASICs or FPGA boards.
