Bitcoin hashrate today: 250 Ph and flat
https://blockchain.info/charts/hash-rate?showDataPoints=false×pan=&show_header=true&daysAverageString=7&scale=0&address=BitFury: 100 MW with .2 J/Gh = 500 Ph
If BitFury wants to roll out 500Ph and control less than 51% they need to:
- 1) either have the network reach 1 Eh, therefore they need someone else to add another 250Ph
- 2) either start selling and shipping their hardware / chips, in which case the 100MW argument becomes irrelevant.
Let's go with 1), 250 Ph / 1 Eh = 25% of the network
Who is going to sell / own those 250 Ph?
Seems in line with AM's plan.
You're absolutely
bonkers trying to spin this as somehow being a positive for AM. Its right up there with the dude saying having 3x worse power efficiency is a good thing because it allows you to serve different markets.
A few hints for you: BF has no incentive to maintain less than 51% of the network. Aside from selling actual hardware they also resell and host a significant portion of their hashrate to partners like cryptx and DigitalBTC. No one cares if >51% of the network runs on hardware produced by the same vendor.
Moreover, BF doesnt have to fill its DC's to capacity. They will add hashrate for as long it makes financial sense, regardless of their % of the network. If it no longer makes financial sense for BF to add more, despite having access to hardware at cost, access to extremely cheap hosting and electricity (check out their datacenter design and electricity prices in georgia republic) and despite probably having (by far) the most power efficient hardware, then who do you think will buy or deploy AM gear?
Of course, bitfury still has to make good on its promises, it may fail to deliver, or you may hope on it being a bluff, but based on their trackrecord, I wouldnt bet a satoshi on that.
You mean Bitfurys track record of failed 40nm, 28nm, and 20nm ASICs? I would bet a few satoshis on them missing their target again.
Don't forget that when Bitfury says 0.2 w/gh they mean underclocked to the best possible efficiency. They will most likely fill the DC with ~0.5 w/gh hardware until it makes sense to underclock.
