And what about non energy intensive crypto currencies that rely on PoS or PoH?
- randomhodler84 5y agoDon’t worry they are scams, only proof of work is actually secure.
- drdeca 5y agoNot convinced of this. (Your handle doesn’t make it a more convincing claim.) I’m not saying I’m totally convinced that PoS can be really secure, but I am reasonably confident that some developing such systems sincerely believe it can be, and have no deceptive intent. This in my mind seems to contradict it being “a scam”, which to my mind requires deception. In fact, I do suspect that it can be secure, for some reasonable sense of “secure”, though I am not especially confident in this.
- fouric 5y agoDepends on what you mean by "PoS". If you mean "proof of stake" - I've never heard anyone describe any environmental issues with them, so I assume that they either don't exist or are far smaller in impact than PoW. If you mean "proof of storage/space" - it seems like that tends to produce very high write volumes, which in turn burns SSDs out very quickly[1] - and you can argue that that's bad for the environment. How bad, and whether it's worse than the energy consumption of PoW, I'm not sure. From one perspective, it's worse, because you could theoretically power PoW mining using exclusively green energy, but you can't pull the raw materials for SSDs out of thin air.
