Bitcoin proof of work is both the sine qua non and the ne plus ultra of the entire sphere… and i say this as an enjoyer of all the fancy math et al. in the space. it is genuinely a monumental achievement… one whose value… is indeterminate (at best; and worst). and i wouldn’t dare opine on that point, because i’m “from Switzerland” on this. but that it opened a mathemeatical pandora’s box is undeniable. when i read the original Bitcoin paper (about a year after publication) i was suffused with the feeling that something fundamental was “discovered” in a way i’ve only felt a handful of times in my entire life… (and then i spent all my BTC on drugs)
