There is nothing magical about it.

They had atleast the same number of miners on order than the amount they presold.

As more than half of their customers refunded, they now have atleast 9PH ready to deploy.

Will p2pool be added soon?

They just don´t give a shit, as their main deployment of these devices will be their DCs.

With an ambient air temperature of ~0°C-15°C (depending on time of year) they are quite sure that THEIR connectors won´t overheat.

Now, i would be careful to run these at 30-35°C ambient temperature, as the wires will more easily start electrical fires then.

How does the peering system work and what do incoming and outgoing peers do?

Are the outgoing peers downloading the sharechain from you because they haven´t got the complete list?

What happens when your node has no ingoing peers?


Does your peernetwork automatically grow with your nodes´online time?

I read somewhere that you can also "force" your node to peer with a certain other node, is there a benefit in that?

Does a bigger peer network mean less orphaned shares? (as the found share should be distributed faster around the p2pool network)

However, as a business Bitmine has to manage the risk involved in production and R&D.

They have to take steps to ensure customers funds can be returned in the event of failure, that is what a company´s share capital or Investor money is for.

I am quite sure they have more than enough funds available, as they sold miners at 5$ per GH...

At this point in time they are lucky when people settle for their owed money back, as swiss contract law does allow people to claim resulting damages from not fulfilling a contract.

If at any point it becomes obvious that certain safety margins weren´t met, one might be able to sue for fraud.

Well, with my estimate of more than half of the neptune orders refunded (because more than half the miners can do basic maths) and some people who went for the frankenjupiters,
they have easily got 1000+ Neptunes to simply install in their DC.

Electrons are not consumed when using electricity

Thanks again. Is the option to not send invalid shares in your miner or on the node?
It seems like it should be a setting in the miner...

Thanks, so if you had the no-submit-stale option turned on, it wouldn´t submit valid Bitcoin blocks that are not considered a valid share?

Isn´t there some mechanism every node immediatly recognizes a valid block as such, as every node runs the full Bitcoin client?

Hey guys, i have a technical question concerning p2pool.

While shares can quite easily be DOA because of the ~60times faster sharechain, found bitcoin blocks shouldn´t become dead/orphaned that quickly, as they are then broadcast on to the Bitcoin network.

So what happens, when my found share would be a Bitcoin block but the p2pool node considers it a "late" share? Is it still passed on to the Bitcoin network?

DOA rates (for shares) at Bitcoin p2pools are however atleast 2.5%.

Reducing the ping from 40ms to under 1ms improved my DOA rate from ~5% to 2.5%.

The main thing you should look out for is that your DOA rate is lower than the average P2Pool rate, as you will produce less invalid shares, which will in turn increase your payout per block.

Am I correct in the assumption that only shares "expire" within the 10 second timeframe and found blocks don´t expire that fast?

Iceland node up and running!

Preliminary stats page:

Connect your miner to:

192.71.218.197:9332

The workername is your Bitcoin address.

EXCELLENT ping from Thor Datacenter (Advania).

Yeah, they must have a shitload one thosuand of their 20nm devices ready to deploy, as my guestimate is that more than half of their Neptune customers went for the refund.

They should be able to get around 15PH in one 10MW facility by now.

Yeah, sorry about nagging but i am actually so hyped by the low ping i got before, so i might just try to message him.

Are you coming home today or tomorrow 

Can´t wait till the Iceland node will be up tomorrow

I am really looking forward to mining with such an excellent ping.

How is the downloading of the blockchain doing? Is everything on track?

As already pointed out, knc is currently delivering 20nm miners.

However, they are terribly overpriced and get "only" 0.6W/GH, a figure that can be achieved on 28 nm.

Sorry, i was half asleep when posting, obviously i meant US manufacturer, as stated in the topic.

My point still stands though, 20nm first of all is not optimal for Bitcoin asics, as it is only meant as an intermediary half-node on the way to 16nm.

Second, there is much optimisation to be done on 28nm and like US car companies (the big ones anyway), except maybe tesla (which is tiny), i doubt that any US manufacturer will come up with an efficient solution.
Maybe BFL really gets their claimed W/GH though, so i might be wrong on this one.

Spondoolies seems to be on a good path with their sp30 solution, which should get 0.45W/GH at the wall and is also professionally engineered.

KNC should get 0.6W/GH, but their price again is ridiculous, their business ethics are also highly questionable at this point.

What i am definately not wrong about is that both the (now bankrupt) HashFast and the always-late BFL shouldn´t be trusted in this game.
Their retail prices for home miners are furthermore outrageous, ROI with these is impossible.

Again,  their business ethics are nonexistant, so i wouldn´t order from them.

It seems like anywhere else in the world Bitcoin ASIC designs can be completed more or less on schedule, so i really hope these "bad" companies will go bankrupt in the longterm.

Does anyone know where i can get the p2pool luck over ~ 1 year?

sp30s should once again work with p2pool and 1000 6TH devices will be delivered in August.

Some of those will surely use p2pool.
