It was launched right now so I imagine
it might be good to discredit such issues instantly
Primarily they’re making an attempt to rebrand PoW and exchange it with the identical assumption simply “good for the atmosphere” I feel it might be cheap to place efforts in opposition to such assaults.
It is price noting that the first motivation for this paper was to appease US Coverage makers who’ve introduced forth no proof by any means to again up their claims that Bitcoin mining is inflicting international warming. I’m not right here to teach folks on what is clear so I wish to concentrate on how silly it’s to suppose a theoretical proof of enter buzzord right here will enhance something in regards to the naturally dwelling and evolving proof of labor already lively on bitcoin.
You possibly can sum up the convolution of assumptions constructed into it with this opening paragraph:
n. Not like PoW, PoD computation does
not require important computational assets. Thus, a
miner alternates between producing PoD with nominal
energy expenditure and PoW with excessive energy expenditure –
Determine 1 illustrates this course of.
Like PoW techniques the place participation is worthwhile
just for miners with environment friendly {hardware} [20–22], Sprints is
worthwhile just for miners with environment friendly PoD {hardware}. We
thus assume all miners have comparable, environment friendly, PoD {hardware};
To imagine such a factor is clearly with out ANY analysis of proof of labor. They assume that one thing that doesn’t require lots of computational assets will also be pretty destributed throughout an atmosphere the place all members have equal hashing energy successfully.
Clarification: One solely must disprove their preliminary assumption (which has already been disproven https://miningpoolstats.stream/ ) to see that the remainder of the assumptions “confirmed” within the paper are additionally utterly susceptible to assaults particularly nation state seize by means of Majority assault ( usually referred to as 51% assault however possible a brilliant weak consensus scheme like this may be trivial to achieve majority over with out 51% of the present PoW energy much like the weaknesses of proof of stake: https://arxiv.org/abs/2102.02247).
It must also be famous that when Bitcoin was first mined it additionally didn’t require a lot computational assets, they fail to even point out the scaling necessities of distributed PoW techniques and the way issue adjustment is related to the computational energy of competing miners. It is simply over all a particularly poor assumption to base your whole paper to not point out CONSENSUS MECHANISM FOR A MONETARY NETWORK on. I imagine I’ve been seeing this sort of stuff for a number of years and little to nothing is being executed to set the details straight.
