Looks good but our URL is https://cloudminer.com and the www redirects, do you mind fixing this?

@organofcorti

No problem. We're a P2Pool proxy by default but with the bonus for miners to sell hashes to any pool as a proxy pool!

A little from column A and a little from column B 

@organofcorti

We're paying PPS value for accepted shares but with the pool just starting out, miners will see some variance and therefore paying out from the share log over time is a safer for us and the miner. When your not clustering with other miners under a rental order your workers collectively mine with the P2Pool network and accepted shares are saved into our private share log until then automatically paid out by CPPSRB method. We use a scheduled round lasting 24 hours where the pool only pays as much as possible after unlucky rounds but later pays the difference after lucky rounds.

TREZOR is a physical hardware Bitcoin wallet managed and sold by the team at SatoshiLabs who are Bitcoin enthusiasts from Prague.

I've not used a TREZOR before but had experiences with the competing product from Ledger Wallet. I found this product very useful to store cold coins.

A 100 node deployment is impressive, surely this is just an attempt to improve mined block propagation from BTCC with a private Relay Network.

If we think about how much mining changes every year along with other technologies, come 2140, the remaining super pools will be distributed networks working synchronously with the full bitcoin node and transaction validation software designed to operate on the same hardware all manufactured into one. A singular autonomously mining operating system potentially integrated with everyday circuitry. This new era of Bitcoin infrastructure refined with better production techniques and better efficiency will make transaction fee only mining for industry leading providers worth the investment.

Wow that's neat, I expected some fun stuff to come from 21 Bitcoin computer. Good job.

Typically I've not gone to an effort of finding root cause on the majority of the blades which died so you could call it speculation but given the environment of where the miners operate is controlled, my best guess for reasons of failure educated only by common factors and practical experience are cheap material, low build standards and possible miss use by previous owners if the product is second hand. I'm also aware that because some ASIC chips are daisy chained designed, any failure to one chip will instantly disable the remaining in that row.


Unfortunately 'properly designed' is open to interpenetration and in my opinion with the accelerated evolution for purpose built mining hardware, build quality is easily sacrificed for faster delivery and lowered expenses.


Pentium chips and mining chips. Apples and Oranges perhaps? But for your information at the moment I only operate Antminer S5 products which I understand operate from 0C to +/-35C. Right now I don't have any way of monitoring temps remotely but I have configured the inbuilt safety feature to power of the board if temps hit the +80C thresh hold.



I don't have the electronic experience to know how my miner sparked and sent blazing glory out the rear fan but out of curiosity I did dismantle the Antminer S3 which managed to 'halt and catch fire' and I found the part marked on the inside board as C456 was where the initial fire incident occurred. Refer this image and see below the 6 power connections and directly to the left. https://farm3.staticflickr.com/2900/14713993833_d214627e56_o.jpg
Here one could have learned and taken away not to buy from Bitmain again but limiting my options in a ever shrinking market isn't an option. Also given I had already experienced chip failures with other manufactures and read about fire related chaos for other miners then this although worrying came to me at no surprise.

Maybe I've had some bad luck in the past, I've definitely had a few too many blades randomly die and I even had one miner catch on fire!

Also I remember reading a long time ago some one was going to the effort of using ssh on each device and running sudo poweroff

This never worked for me as I typically never had a permanent management computer near to any of the miners when it came to a decom.

Does anyone else have tips to share perhaps someone GPU mining?

I've had experience with the S5 (and hopefully the S7 soon) and found disconnecting the Ethernet worked as with it's predecessors.
Typically after disconnecting the antminer they will continue for some time running at full speed until the target pool is no longer recognised as responsive triggering the beeper.

Hello and welcome.

I thought I would start a little thread to share tips on how users power down their miners, this could be your ASIC, FPGA or GPU.

I've personally had a few miners over the years. I got playing with mining on GPU's back in late 2012 and jumped all over buying ASIC's as they became available.

Through that time I've learn't to stay in front you should buy, mine and sell ASAP.

But when it came to shipping the miners off I was unsure of the best strategy to safely power off the devices so the chip wouldn't burn after loosing power to the fan.

Anyway since this occurred to me I've always disconnected the Ethernet to stop work from being pushed to the miner, waited 10 minutes or until I felt the heat had dissipated enough then pulled the power plug.

What are others doing to safely power off their miners?

OMG that was the best!

"you can't go spending your profits on giant cooling fans, just man up and wear shorts to work"

Very impressive, the final data room looks spectacular with all that stainless steel and Genesis Mining really did go that one step further with lifeinsideabitcoinmine.com
There's certainly only a few real cloud operations out and it's great to see efforts to clear the foggy air hovering around the cloud mining name.
Has anyone ever shipped into overseas co lo hosting in such places like Iceland or set up shop from scratch?

From memory the attacker only needs 50% + 1 miner and therefore an attack with ~50.7% is quite possible, theoretically an attack could be attempted with less. With some luck an attacker could be successful in double-spends with less than 50%, perhaps 45% or less but statistically their more likely to succeed with 50% given you will need to find new blocks faster than the remainder of the network combined.

Small form factors are the way to go for the home miner, I've had a few RockMiner R3's and a range of Bitmain toys: S1, S3 and S5. I've bought some gear new in the past but mostly now from the secondary markets where people have given up earlier and sold cheap. Buy-mine-sell is the goal for me, typically I have miners shipping in and out of the farm every 8 weeks. Personally I found the S5 to have been the best product so far, only having one board die out a good number units used and sold.

I think someone should check my work but 2^32 * difficulty = hashes to find a block on average

Hmm I think the link is dead but it might could be my bad timing. Please check and update. In regards to your comments about immersion being the most expensive, did you mean submersion or 2 phase immersion cooling techniques from Allied Control? Also given Bitfury's recent acquisition of Allied Control, I'm eager to see how this concept is adapted to such an extreme scale to meet Bitfury's super datacenter requirements. I imagine it will put the proof of concept design built with ASICMiner a few years ago really to shame.

I run a small farm with speeds the same as yours, it also uses direct air cooling. One of the problems I've faced over the years was dealing with dust and bugs from the outside world. I had a miner catch on fire which I suspect may have been related to the build up of dirt and dust choking the fan. To be sure this doesn't happen again I made filters from woman's leg stockings. I cut them to the right size and patch them over the input fans with tight elastic bands. I typically use small form factors like Antminer's so it's basically one filter per miner. As far as I can tell there is no interruption to cooling and when it's time to start reselling, they simply don't look disgusting and messy.
