'The right to privacy matters'

It can because a banker type guy will point from the State of Washington. He looks at it as a ledger game for profit.

The guy I know can drop 1 or 2 million into btc as a hedge to his real estate, stock and bond investments.

He has been picking my brain to understand the entire game along with watching and allowing the stat of the art miner (s-7) run in his office.

He is methodical and is most likely going to pass or pull the trigger this spring. He has connections to a few guys in the state of Washington

and if they go forth and build a mine they will point it at f2pool. Basically it gets rid of variance.

I am helping him to decide if he will do this.

So if they get a building and 3 cent power put in 3 or 4 million they could get.

2000 s-7's at 4.7th each or 9.4ph.

This would make them second at f2pool.

Here are the top payouts from f2pool last night. They paid 777 coins last night.

The biggest payout is below as are all payouts between 2 and 45 coins

I was not questioning why people use F2Pool. In fact my standard setup is first Nicehash with a setting some % above normal PPS payout levels, then BW.com as they have 1% fees & finally F2Pool...

My surprise was that F2Pool could be as big as it is and only be a Public Mining Pool with Ad Hoc users?

Also surely F2Pool is way to big to just be a Public Mining Pool, must be someone's data centre?

They offer steady payouts this is a huge reason people use them.

Think like an accountant not like a geek.---------- Sounds nasty not meant to be nasty. But if you are business oriented you mine here.

I have a limited 2 cent power deal with a friend he is a banker not a geek.

He insists that this 1 s-7 is to be pointed at you guessed it f2pool.

If you back a person with cash you don't want variance. As much as I don't like some of f2pool's methods the steady daily payout has a lot of meaning.

We have acquired a few thousands Avalon 6 and Antminer S7. The old S3 were mostly sold. Though we are currently running around 13PH, it is mainly due to seasonal power supply restrictions. We expect the hash rate to rise to 30 to 50 PH by mid-2016.

At the Princeton course about Bitcoin & Blockchain Technologies, a whole lecture was given on the bitcoin network energy consumption, so I thought you guys would be interested in some of the methodology used to assert Bitcoin´s power consumption:

*Using Landauer principle, that says that any non-reversible computation must consume a minimum amount of energy (Kt in 2) Joules---SHA256 is a non-reversible form of computation---Energy consumption is inevitable, we did input the embodied energy (used to make the hardware, and decrease over time), plus cooling energy (costs more/less with an increased scale), and the electrical energy (increase over time).

Using that information, plus an average industrial electricity value, gave us:
UPPER BOUND: 900 MW TOTAL ENERGY CONSUMPTION (all $ is used to pay for electricity, all pay the same for electricity)
LOWER BOUND: 150MW (everyone mines at maximum efficiency).

Then we used this as comparison:

How much is a MW?

Three Gorges Dam: generates 10,000MW

Typical Coal fired plant: 2,000MW
Typical power plant: 4,000MW

It takes less than what a typical power plant generates to run the entire Bitcoin network. Plus, ALL payment systems requiere energy by design.

Additionally, Chinese miners can get cheap electricity because....the state-owned power transportation network prefers to purchase electricity only from state-owned power plants, leaving some private-owned power plants with no one to sell their power to, but the miners.

What this implies is that much of the Bitcoin network runs on redundant power output(in fact no miner these days can break-even without some cheaper than usual electricity), which has no better use, using it to secure a very important and innovative payment network is by no means a waste.

What about F2Pool & BTCC are they not included for a reason or because there is no data?

Those are public mining pools, AFAIK the owners don't run any mining hardware.

BW/Antpool are listed because they have large datacenters that they use for mining in addition to operating a pool.

There are appx. 10 major power dams on the Columbia river in Washington State, at about 2500MW EACH.
IIRC Grant County PUC has one, the others are more-or-less evenly split between Chelan and Douglas county PUCs.

I am pretty sure this makes the Tenessee Valley Authority total output look puny....

Coal power plants vary a lot - local power company is building a 600MW unit, anticipating it comming online in 2017.

Natural gas power plants vary a lot - older ones tend to be smaller - but some of the newer ones can pull ballpark 100MW per turbine.
They're also getting common in areas that have good access to natural gas, due to environmental concerns and low cost.

I'm not sure what was presented in the course or if you understood it correctly, however, while SHA256 is not a reversible algorithm, the process of attempting to mine a block is almost entirely reversible. One can do an entire computation until one succeeds, copy out the nonce (and extra nonce), and then reverse the entire computation. The only energy required is that required to copy out the answer. Of course, today there is no efficient implementation of the necessary reversible logic, but there are no principles of physics that require bitcoin mining to consume energy. That's a problem of technology and engineering, not physics.

Big update!

I've added quite a few more datacenters, I've almost doubled the total "accounted for" MW since the OP. How many MW do you all think the network uses in total? It could help me with my pie charts.

Quote from: MaximeAD on January 15, 2016, 04:42:02 AM

Great! My company is there

. I have to try going up in the list!

Very nice summary.

There's also allinvain with Cryptoboreas in Labrador. Don't know the size of their datacenter though.

Do you have a name for your datacenters?

Cryptoboreas is too small too be listed IIRC, it looks like they have 150KW of capacity.

Just a comment. A nominal X Megwatt Bitcoin Data Centre is only likely to run at the most 60% of capacity for actual mining. There are overheads (cooling etc) and electrical systems and transformers are normally kept at under 80% of capacity.

Thanks for the info, I'll use it when I update the OP tomorrow.

KNC are a reasonably open company about their mine rollout plans. Another 20 MW rollout.

http://www.pcworld.com/article/3014471/bitcoin-miner-knc-is-planning-another-four-week-datacenter-build-out.html

Also recent Sam Cole interview talking in detail about mining and KNCs search for cheap mining locations.

https://www.youtube.com/watch?v=RDnA6i6oEvA

Washington State has a stack of miners to the extent it is impacting the cheap electricity.

http://www.govtech.com/dc/articles/High-Capacity-Data-Centers-Blindsided-by-Increase-in-Utilities-Charges.html

And who knows what is in China. Bitfury are likely to be mining on their 16nm chip as fast as they can get them.

it would be nice to have some info, on the maximum megawatt that their location can handle, so they will be forced in the end to split in two or more location

which means better decentralization

If it's still owned by the same group of people it's not decentralized.

I'm pretty sure that MegaBigPower's mine has grown quite a bit, or they've added additional facilities.

Turns out that MBP and hashplex share space in this datacenter:
http://www.newsbtc.com/2014/05/30/data-centers-join-bitcoin-train/
http://www.serverfarmrealty.com/data-centers/titan/

Assuming 60% is used for hosted mining hardware, and the rest is used for other clients--4MW. It seems to line up with this next article I found which is the motherlode: http://www.datacenterknowledge.com/archives/2014/11/05/bitcoin-clusters-emerge-in-cloud-computings-footprints/

It reveals that MBP was building a 23MW center and was eyeing another location with 12MW capacity. Another (unlisted so far) NA based hosting company in that article that has 4.5MW of capacity.

Quote from: QuintLeo on January 15, 2016, 03:39:47 AM

I believe Zoomhash also has a biggish mine in the same area, given they're shipping the used A2 units they have for sale out of there. No clue on size though.

Good one!
http://zoomhash.com/pages/hosting

That's another 3MW accounted for.

I'm off to sleep but I'll be updating the OP tomorrow.
