5) Add to that security. Who holds this metric: How secure is each GH?
restored to a previous point.. ?? im not even going to comment on the stupidity of having restore points as thats the fungability argument. bitcoin will continue on as it should, as you say it would require a hell of alot of things in combination to cause the bitcoin ledger to be re-written and governments would not waste resources or risk fiat catastrophe based on bitcoin. after all there are over 100 FIAT currencies.. do you see america trying EMP explosions in russia and china to stop the BRICS development.
as for your comments on how secure is GH.. well better than KH better than MH, but not as good as TH and definetly not as good as PH.. so dont worry about the small stuff we are over 25% nearer to EH than dropping all of the way back to GH
What I mean, is, how easy is it to gain access to the largest mining operations and pool control structures?
On the physical layer?
On the OS layer?
On the social engineering layer?
What I mean is, how easy would it be to disrupt the 5 or 6 largest pools, and take half the network hashrate offline? How feasible is it? And as with anything, surely a cost can be attached to that... and a reward. Does it even out? Has anyone done a qualitative calculation? At what price point will it become feasible?
Where is this calculation? Or do I have to do it myself...?
