Innosilicon A8 CryptoMaster CryptoNight ASIC Miner

A8 CryptoMaster Miner

The A8 CryptoMaster is Innosilicon's first entrance into the CryptoNight mining market.  You may know Innosilicon initially from is first ASIC miner, A4 Dominator.  This miner primarily support the Litecoin network.  Next we had the A5 Dashmaster that support the X11 algorithm which Dash is the most popular coin to be mined.  The A8 CryptoMaster is used to min Monero, an alt-coin that is growing in popularity and support.  We have proof positive that this is the case with companies spending the money on research and chip development to make a fully functional miner.

The design is very similar to an Antminer except that this unit is double the width of a standard Antminer.   The A8 has a massive eight (8) hashboard spread across the aluminum case.  It has the same standard controller board and four cooling fans.   Web-based interface for the miner and a simple setup via a webpage to program your pool information and monitor the miner's hashing progress.  The A8 CryptoMaster products around 160kh/s while only consuming 350 watts of electricity.  At 208 volts you can run about 10 miners on a 20-amp circuit.

Halong Mining DragonMint T1 Bitcoin Miner Released

DragonMint T1 Bitcoin Miner

A surprising entry into the Bitcoin ASIC miner market.  Word on the street it uses a 10nm hashing chip from Samsung, compared to the Bitmain chip from the TSMC semi-conductor foundry.   At this point in the hardware development curve for ASIC miners supporting SHA-256, Bitmain has come to dominate the market with their S9-series of miners.  When this was announced, many people doubted its authenticity.   I can tell you that at the time of this writing, these are hitting the streets and is confirmed and a real and performing miner in-line with pre-release specifications.   This Bitcoin miner's performance numbers come in at an impressive 16Th/s while only using 1,480 watts of power.   This actually give you more efficiency than the 14Th/s S9 miner.

When you look at the design, it is almost identical to the Antminer S9.   Basically the same size and weight and  setup.   Dragonmint's have three hashing boards and two cooling fans.  The web interface in also Linux based via an onboard controller.   Setup is the the same with these units, mining page for pool credentials and another page for viewing performance.  These units consume about 7.10amps at 208 volts so you can operate two miners for each 20-amp circuit.

In closing, these units definitely fit the bill for the newest generation of capable Bitcoin miners and it will be interesting to see with their sales numbers if we see better models hit the market down the road.

Canaan AvalonMiner 821 Bitcoin Miner

AvalonMiner 821 Bitcoin Miner

This is the newest ASIC miner from AvalonMiner, the Avalon 821.  This is the successor to the Avalon 741.  The Avalon 741 clocked in at 7.3Th/s while consuming 1,150 watts.   The A8 now produces a whooping 11.5Th/s for only 1,200 watts.   This is over a 60% increase in hashing power with only a ~100 watt increase in power consumption.  This is good news for AvalonMiner owners that are looking for an upgrade that isn't from Bitmain.   The Avalon design philosophy is a little different that the Antminer units.   The 821 has a single fan design that uses an exhaust-only fan.  

One drawback to this design is the placement of the temperature sensor on the unit.  It is critical that you have a climate-controlled environment that keeps the unit below the temp threshold.  The S9 miners are more resilient in high temperature environments.  Once temps are under control, the 821 is a very reliable unit and a quality choice when purchasing a Bitcoin miner.   The unit comes with two hashing boards with four PCI-E (6 -pin) connectors per board.   Now in a very different design than other miners on the market, the Avalon 821 does not have an on-board controller.  Instead, they use a Raspberry Pi as a controller and proprietary cables to communicate with the miner.  On the plus side, the controller can support up to 15 miners per Pi.  To accomplish this, you daisy chain the miners together.

The Pi provides a basic Linux-based web interface.  Nothing flashing but sufficient for what the modern miner needs from a miner administration standpoint.

Bitmain Antminer D3 - X11 ASIC Miner

Antminer D3 Miner

The Antminer D3 is Bitmain's ASIC miner for the X11 hashing algorithm.    X11 is growing in popularity so it is natural that the larger hardware manufacturer of crypto-currency miners has decided to enter the market with their commercial offering.  The D3's design is in the same line of all the Antminers since  the S7 miner.  The length is very close the S9 miner.  The miner has the same configuration of: three hashing boards, controller board, two fans and an aluminum case.   The units is a little higher than an S9 but outside of that, basically the same.

The web interface is the same Linux powered setup you find in all of the Bitmain offerings.  There are five mineable coins for the  X11 protocol.   DASH by far is the coin that almost everyone is mining with these units.   With the growing popularity of this miner, we could see the difficult spike significantly when this launch.  Each units takes 1,200 watts a piece.   On a 20-amp you can safely run two miners and potentially three miners but please note you will be 1.3 amps over the normal de-rating of 80% of the breakers maximum capacity.

Overall another solid offering from Bitmain and should do a good job mining for X11.

Baikal Giant+ A2000 X11 Miner Released

Baikal Giant+ A2000

Baikal is a new-comer to the crypto-currency market with a couple miners that support six algorithms.   Baikals support the follow hashing algorithms:  X11, X13, X14, X15, Qubit and Quark.  The Giant+ A2000 is a significant increase in performance from the Baikal 150 units.   The 150 units I would consider more of a hobby miner because they didn't really lend themselves for hosted mining.  I did co-location a number of them for a client but with the stacking method and cording did make me a little uneasy.   The A200 give me none of these concerns.  It is very similar in design to the Avalon and Antminers.

They come with two hashing boards and a Linux based controller board.  The interface is your basic web interface with a performance monitor page and other pages for programming the miner and some basic networking to set it up on your LAN.  It has only a single cooling fan for the miner.  The miner is quieter than your  S9 and Avalon miners.  You can run these in your home without having to deal with a ton of ambient noise during its mining operations.

I do like that these miners have the controller built into the miner compared to others, which have external controllers.  Overall this is a solid miner and would recommend for purchase if you are interested in mining for these crypto-currencies.

Bitmain Antminer L3+ (Litecoin SCRYPT Miner)

Antminer L3+ Miner

The Antminer L3+ is the ASIC-based 2nd generation offering from Bitmain supporting the SCRYPT hashing algorithm.  This algorithm is primarily used in mining for Litecoins, there are a number of other SCRYPT supported cryptocurrencies that support this protocol, including:  Gulden, Verge, Digibyte, Auroracoin, GameCredit and the famous Dogecoin.  Before Bitmain's entrance into in the SCRYPT market, KNCMiner was a major player in this mining hardware segment for the launch of the L3 miner series.  KNCminer's Titan series was their first ASIC miner that supported SCRYPT with a major jump in hashing performance.   

The L3 series is an even more significant jump in performance.  The L3+ is clocking in at over 500 Mh/s at only 800 watts per miner. One of the nice things you get with the magic 800 watts power draw number, is that when you run them at 208 volts or higher, you can fit four L3+ miners on a single 20-amp circuit.  That is a pretty big deal for large miners and crypto hosts.  People who handle large amounts of miners know that utilizing the most amps from your circuits is critical for infrastructure efficiency.  Four units per breaker makes this a good fit for doing co-location.   With these types of numbers, it is clear this will become the bulk of hashing power for the Litecoin network.  This still  have the same standard design you have gotten since the Antminer S7.  It is shorter than the S7 & S9.   

Same basic parts will need serving over time, this include: Front & Back fans, hashing boards, control board and rarely PSU.  These are easy units to breakdown and I could fully service a unit within 10mins.  Overall these are great mining units.

Bitmain Antminer S9 ASIC Miner

Antminer S9 Bitcoin Miner
The S9 Bitcoin miner from Bitmain is their newest offering in their hardware lineup.   Released in June of 2016, they are coming in a number of models.  The Antminer S9 miner models are available in different speeds based on the batch order.   Hashing speeds are: 14Th/s, 13.5Th/s, 13.0Th/s, 12.0Th/s and 11.5Th/s.  At the wall, the S9 miner consumes about 1,330 to 1,450 watts under full hashing load.  

The design is very similar to the Antminer S7 unit.  The S9 is a little longer than the S7 but outside of that, basically the same.   They both share the same administration interface that the entire Bitmain miner family uses.  It is a very simple setup to get the unit mining, estimated setup time is under 5mins once you have it plugged in and on your network.

The performance increase is amazing compared to the S7 miners.  With very similar power consumption, this is a major upgrade from Bitmain and these will become the majority of Bitcoin SHA256 mining power on the Bitcoin network.  Out of warranty service is still very high  with only a few parts to support or replace in the event of damage.   

Parts normally needing service after 12-18 months of service are:  (3) Hashing Boards, Front or Rear Fans and Control board.   Normally you will see one or both fan bearings go out and if they are hosted in a high temperature environment, you will see a hash board failure potentially.   Control board and PSUs have very low failure rates.

Spondoolies released the industrial strength "Pickaxe" SP50 Bitcoin miner

Spondoolies SP50 Bitcoin MinerThis is the latest Bitcoin miner from Spondoolies, the SP50 Pickaxe.  This is released only for large commercial miners according to Spondoolies.   Looking at the whooping 16Kw needed to power this beast, they are correct.  You will need some serious power distribution and cooling to even handle a single unit.  The hashing power is the most impressive aspect, tipping the scales at 110 TH/s of mining capability.  They state it only used 0.15 / Watt per Gh/s, this makes it the most effiicent mining solution available to the commercial mining market.   We assume is still uses that clean UX admin interface and the design is pretty clean, getting its inspiration from the current Blade server chassises from Cisco.   The blades look to be the mining modules, 10 blades in all.  That means they have gotten 11 TH/s in each blade, that is a major improvement over the SP35 Yukon.

Bitcoin Miner Power Efficiency -- Why should I care?

Bitcoin mining in 2015 is now serious business.   In the early days of Bitcoin mining, that we participated, mining was a completely different beast when is comes to income earned compared to expenses to mine.  A majority of the mining capacity was multi-GPU mining units with just a sprinkling of pre-ASIC hardware that still carried a large premium.   Much has changed since those days.  We are now in the 4th Generation of ASIC Bitcoin mining hardware and over 400 petahashes of capacity. 
The modern Bitcoin miner is of a much more professional nature while they understand you not only need efficient Bitcoin mining hardware but a comprehensive hosting plan to maintain their mining capacity over the duration of their investment.  At the heart of these calculations is the power efficiency of the Bitcoin miner.  What this boils down to is the how many watts does the miner use for each Gigahash of processing power.  Take the newest offering from Antminer, the S7, it takes only 1,210 watts  to produce 4.8 Terahashes of mining power.   This equates to 0.25 Watts of power per Gh/s.  That is a huge leap from the first generation of ASICs like the Avalon that was a 8.3 Watts per Gh/s.  The newest generation is 32 times more efficient than when ASICs first started mining Bitcoins on the Blockchain.  This trend will continue. 
The reason this is so important is because as the difficulty rises, the more inefficient miners will have higher expenses to generate their Bitcoins.  With rising difficulty, you can imagine miners being trapped on an island with rising water (difficulty), the more efficient your mining hardware, the higher land your operating is on.  Once your underwater, this means that your hardware is costing more in hosting expense than the underlying Bitcoins it generated in a given set of time.  This means that if you are mining in this manner, you are speculating that the price will increase long-term and that is worth mining at a loss in the present.  This situation you will find become increasingly rare.  Many large miners we speak with are quite aware of this and the mining operation needs to stay in the black.
The other force pressing on this calculation is the hosting expense of running tens or hundreds of Bitcoin miners.  Along with this march of increased mining efficiency, it has along increased the amount of heat and power required to effectively run these miners.  This is where traditional data-centers and Bitcoin colocation startups come into play.  The power density needed to run a medium or large farm outstrips most commercial buildings and will require extensive and expensive upgrades to make capacity available to operate the miners.     Their most important expense is what the utility charges them for power.   Power rates vary all across the world and even state-to-state in the U.S and Europe.  Hosting companies need to charge a price to Miners that covers their utility costs, along with other operational expenses.
That means that because of the dependency of miners on using some form of hosting, means there is a price floor above the raw cost of electricity that equates into the mining profitability calculations that determine the overall performance of the investment.  Currently in my calculations, a price under $210.00 USD per Bitcoin is so low that long-term mining is not profitable with the current generation of miners.  

Mining is a zero-sum game, you get Bitcoins via mining by reducing the amount of Bitcoins going to all the other miners that were mining before the newest miner came online.  This cold war arms race will continue until the Bitcoin mining in its current form is consolidated into a few large mining interests that are likely privately funded with small independent miners becoming extinct over time.  Once we make the move to 14nm-16nm ASIC chips for Bitcoin mining, I see a real possibility that no more Bitcoin ASIC miners will be offered at retail to anyone wanting to get into mining.  The engineering expenses alone will make the risk pretty high, so anyone backing that will want certainty and that will mean not relying on the general public to recoup the expense.   Stay tuned, we will be writing more on this subject and the next 3 years will be very defining for the future of Bitcoin mining.

Antminer S7 Bitcoin Miner released

Antminer S7 Bitcoin Miner This is the newest offering from Antminer.  The S7 is not their fastest offering (That goes to the new S5+), it is their most efficient Bitcoin miner ever released.  It clocks in at a hair over 4.8 TH/s from a mere 1,200 watts of power.  This now rounds out Antminer's current stable of miners for the market.   3 PCI-E connections will be required to run this mining unit.  Any PSU that can handle 1300 watts or more will have more than 4 PCI-e connections so you will be covered there.  They have a simple web interface like the rest of their units.  This is a positive development in power efficiency.  All miners want to see more hashing power for every watt as difficulty continues to rise.  This is also one of very few hardware manufacters that are making miners for the general public so these should be fairly popular.   Here are the specifications from Antminer's website.

S7 Specifications:
1. Hash Rate: 4.86 TH/s ±5%
2. Power Consumption: 1,210 Watts (at the wall, with AC/DC 93% efficiency, 25°C ambient temp)
3. Power Efficiency: 0.25 J/GH (at the wall, with AC/DC 93% efficiency, 25°C ambient temp)

Bitcoin Mine Cooling Options - What are my choices?

When a Bitcoin miner is designing their mine including: what mining hardware to run, where to locate or colocate and how to keep everything cool.  This is the purpose of this article.   Bitcoin mining hardware takes electricity to power the hashing chips and converts it to process Bitcoin transactions.  Most of the power gets converted into heat which needs to be dealt with or you can slow down and ruin your mining hardware.  Thermal Management is crucial in getting the most out of your mining hardware.
When approaching cooling I find it helpful to recognize that if you are looking for optimal hashing performance, you need to understand the difference baseline cooling and supplemental cooling strategies.   Now I understand that is some overlap in a couple of these technologies but in my experience you need to focus on baseline cooling if you want to operate year round. 
Here is a basic outline of the different cooling technologies and how each one operates:

Power Distribution Options - What is a Bitcoin Miner to do?

DisclaimerThis is presented as information only that should be used to structure a conversation with your licensed electrician on design choices.  Doing unlicensed and unpermitted work can create an unsafe environment that can have increased fire hazard or death of personnel by electrocution.  Please be smart and safe.
In this next article we will be talking about power and some of the different options for getting that all important electricity from your local PUD into your Bitcoin mining farm.  This is an important question to address early on in your mine design phase.  Electricians are not cheap and the choices you make here will follow with you over the duration of the Bitcoin mines' operation unless you decide to change direction or removing the old distribution to make way for the upgrades. 

Hot Aisle versus Cold Aisle Containment -- What should a Bitcoin miner do?

When building datacenter infrastructure to run your mining equipment, thermal management is going to be one of your most important concerns to manage when planning and operating your mine.  Heat is not your friend in Bitcoin mining.  Have a good plan of how to deal with the heat output of miners is critical to the success of your Bitcoin mining operation.  If you are already colocating in a traditional datacenter, this choice has already been made for you.  Overwhelmingly, hot aisle containment is the standard design element in most modern datacenters. 

Choosing Miner Hosting, Colocate or New Build for increased Bitcoin mining?

Last night I was doing some research and came across this interesting piece about businesses having to decide between expanding their current datacenter operations or using traditional colocation to host their needs.  This got me thinking that Bitcoin miners may be going through the same dilemma.   They have to choose between co-locating their mining hardware with a datacenter provider or building their own mining facility.   As mining becomes increasing competitive and professional, you tend to see larger and larger mines even as the number of  professional miners is falling.  Bitcoin Mining is still open to everyone and there will be opportunities for the foreseeable future but mining "for profit" is changing in character so that if you want to do this as a full-time job, you will need some serious mining hardware and a facility that can run it.   This is where this choice comes into play.

Cointerra Terraminer IV Hosting

As the density of ASIC miners keeps reaching new levels, there is one unit that is leading the pack.  The Cointerra Terraminer IV comes in at 2000watt (2kW) usage hashing at speeds between 1.3 and 1.8TH/s.  The difference in performance is directly related to cooling, as the internal temperature sensors are very reactive, and will cycle down unit performance when ambient temperatures reach too high. 
Often one core of the Cointerra Terraminer IV is disabled temporarily, as the unit is split into two cores known as CTA1 and CTA0 both with their own power supply.  The construction of the unit is quite impressive, the power supplies can be replaced and swapped without opening the box or voiding the warrantee sticker on the unit, although opening the box is required for any advanced troubleshooting or investigation.  Please consult Cointerra directly before performing any advanced maintenance on your unit if there is an issue.  Often Cointerra will allow you to open the box yourself, but you must gain permission first to not void your warrantee.
Cointerra Terraminer IVs are the densest units on the market, coming in at 4U height and ~30 pounds.  These bad boys are definitely the beefiest, and running them in a standard commercial or residential setting causes significant heat and noise issues if you enjoy peace and quiet and prefer to separate your house from a sauna/airport hybrid.
In order to maximize the uptime of your Cointerra Terraminer IV, ambient temperatures ~70 degrees is highly recommended from dedicated cooling.  Manually resetting the miner has proven to be an effective method of avoiding the cycling down process from internal temperature sensors.
Overall, the Cointerra Terraminer IV, is one of the most engineered units on the market and we are proud to provide the best colocation available.  We have the tools, skills and experience to maximize return on your Terraminer IV and take the micromanagement out of your Bitcoin mining investments!

Lost Coins

Lost Coins
The Bitcoin protocol is made so that 21 million Bitcoins will ever exist within the network.  As of the day this article was written, February 27th 2014, 12.45 million coins have been distributed.  I often am asked is there any way to recover lost coins?
There are several ways coins can be lost.  One way is not having a private key to access the wallet that contains Bitcoins.  This can happen if you do not have any backups of your wallet.dat file and it becomes corrupted.  Another way is to send transfer Bitcoins to a valid address you do not control.  Destroying or deleting backups can also be a cause.

Simplified MtGox Breakdown

Simplified Breakdown of MtGox
Many people have been asking me recently on what I think about the recent developments in Bitcoin, especially the MtGox issue, so I figured I would write this to share my knowledge and my opinion.
There is abundant sensationalist information online about the stability of Bitcoin in light of recent events.  First and foremost Mt.Gox is a historic landmark for Bitcoin.  Before we had many competing exchanges such as Bitstamp, BTC-e, BTCChina, MtGox was the authority on pricing and exchanging Bitcoin.  At this point in history, MtGox was very successful in stabilizing Bitcoin’s price and making Bitcoin trading publicly accessible around the world.

Notice: Change in pricing model for hosting (details inside)

Bitcoin Mining Community,

To be honest this has been a decision that we have been putting off making to see if the network’s unprecedented increased in difficulty would taper off at some point or at have the curve flatten a bit.  As most of you know, we have been seeing rising at over 60% per month for a sustained amount of time.  This has forced us to make a major change in our pricing model.
