Pioneer cohort inducted to Bitmain’s Ant Training Academy for industry’s first accreditation course for miner maintenance

SHENZHEN, 15 July 2019 – Bitmain, the world’s top 10 and China’s second largest fabless chipmaker, has inducted the pioneer cohort for the Ant Training Academy (ATA) to officially launch the industry’s first accreditation course for miner maintenance.

“Until now, education around miner maintenance was limited to what industry participants could ‘hack’ together. The Ant Training Academy is part of Bitmain’s continued commitment to improve cryptocurrency mining standards, encourage more sustainable practices and bring credibility to the industry,” said Jiang Zhihua, Bitmain’s Global Marketing Director. 

Ant Training Academy Opening Ceremony

ATA’s Maintenance Training Course is designed to educate maintenance personnel for mining farms on how to install, operate, and repair mining equipment. The course runs for a two week period in Shenzhen, China.

The first 16 participants enrolled for this quarter were inducted to ATA’s Maintenance Training Course in an opening Ceremony in Shenzhen where they will be trained by Bitmain’s Senior Engineers of the Antminer Brand.

Successful course participants will qualify for a “Certificate of Accomplishment”, which will include an assessment of their skill level. ATA course certificates aim to be a global standard for cryptocurrency miner maintenance. High-performing participants will be awarded certificates of Excellence and Top Performance.

Ant Training Academy Programme

“Getting the maintenance process right helps to extend the lifetime of cryptocurrency mining hardware. But right now, it is difficult to find the right resources to help one to upskill. I look forward to taking ATA’s course as it’s practical, will save us the cost of sending miners for repair and would shorten the timeframe of miner downtime in the long run,” said Tang Huihong, a technician at a company selling second-hand miners.

Full programme details for ATA’s Maintenance Training Course can be found here.

Applicants for ATA’s next cohort can register via Bitmain’s website.

As bitcoin price rises, Bitmain sees an increased interest in Antminers at Bitcoin2019

Cryptocurrency mining can only succeed if there is a community of miners and enthusiasts, so Bitmain was glad to participate in the Bitcoin2019 conference in San Francisco last week.

With Edward Snowden giving a virtual address, and a programme packed with countless founders, BUIDLers and C-level cryptocurrency history-makers, this was an audience that came because it cares about the future of Bitcoin, and cryptocurrency’s global potential for disruption.

Antminer Booth in Bitcoin2019

In the exhibition hall, the Antminer booth was packed with interested attendees who were looking to learn more about the Antminers currently on the market, and how to get started in cryptocurrency mining. Few things pique the interest of a bitcoin crowd like an imminent bull run.

Speaking to a buzzing audience on the Main Stage, Sharif Allayarov, the regional director of North Central South America, gave the audience a brief overview of Bitmain’s history, achievements, and Antminers.

Decentralizing knowledge 

With the background set, Sharif outlined the current state of Bitmain; clarifying the separate Bitmain brands, and each of their functions, before highlighting how they all fit within the blockchain industry, with a particular focus on service.

This offered an opportunity to provide insights into how Bitmain innovates and learns to best serve its customers, whilst also sharing how the company is growing at a pace it can maintain. 

Building on from Bitmain’s service repair training module comes in a newly updated program: The Ant Training Academy (ATA).

Promoting longevity in cryptocurrency mining

Ant Training Academy

As mining establishes itself as an industry, the bitcoin community has primarily taught itself how to fix Antminers and hacked together all sorts of genius solutions. 

In honour of their perseverance, and in order to extend the productive life of Antminers, Bitmain is establishing an academy to share the insights and techniques that keep Antminers operating for as long as possible.

This is also part of a commitment to pursuing sustainable ways to mine cryptocurrency, and developing innovations that serve customers throughout the product’s lifetime – not just at the selling point.

A continued commitment to improve the cryptocurrency mining ecosystem

In Bitmain’s six years, a lot has been learnt about the cryptocurrency mining ecosystem, as the company has grown alongside the ecosystem. It fits with a dedication to decentralisation to share that knowledge, and use it to strengthen the industry as a whole.

Swayed by the speech, Sharif was approached by throngs of audience members afterwards, keen to take his contact details to establish and further expand relationships to improve the cryptocurrency mining roadmap. 

The rising price of bitcoin has served to further fuel interest in hobbyist and aspiring enterprise miners alike, with questions ranging from the practicalities of which products best suit their needs, through to managing power efficiency and the best methods of maintenance.

It seems only apt that the cradle of technology innovation on America’s West Coast became the stage for a global audience to hear about this Chinese company’s renewed vigour in supporting all of its customers, worldwide.

Bitmain announces selling date of next-gen Antminer S17 series

The Product Manager of Bitmain’s Antminer 17 series gives users a sneak peek into the features of the new miners which offer “steep improvement” in hashrate.

HONG KONG,  29 March 2019 Bitmain, the world’s top 10 and China’s second largest fabless chipmaker, is putting their new energy efficient miners that mine cryptocurrencies based on the SHA256 algorithm, such as Bitcoin (BTC) and Bitcoin Cash (BCH), up for sale globally on 9 April 2019.

The key features of the Antminer S17 include: improved energy efficiency; higher hashrate and size compatibility with the previous S15 series.

The new miners in the 17 series include: Antminer S17 Pro, Antminer S17, and Antminer T17.

Ahead of the new model release, Yangxin, Product Manager of Bitmain’s latest Antminer series, reveals what went into the production of the new and improved 2nd generation 7nm ASIC BM1397 mining chips.

“The new miner offers a steep improvement in the hashrate in terms of space and power consumption,” said Yangxin.

The new chip equipped in the 17 series offers a 28.6 percent improvement in power efficiency in comparison with Bitmain’s previous 7nm chip, the BM1391.

Yangxin has specialized in the field of IC (Integrated Circuit) design for over a decade and currently manages miner production delivery, which includes system design and mass production. Here’s what he had to share on the following:

On the highlight features of the new Antminer S17, Yangxin said:

“There are two key indicators to look for when measuring the quality of a mining machine: efficiency and the hashrate:

The stand out features of the S17 are reflected in the following:

  1. Improved performance compared to the previous generation chip. Improved energy efficiency has a big part to play in this.
  2. Higher hashrate in a single miner. This increases the hashrate density per unit space and saves deployment costs for mining farms.”

On the improvement of the 15 series and the 17 series Yangxin said:

“Electricity bills are very high for Bitcoin mining right now so the improved energy efficiency means a significant drop in costs and, thus, increase in profits. Secondly, the new miner offers a steep improvement in the hashrate in terms of space and power consumption. This will be especially meaningful for mining farms when you consider the investment needed with set up.

On what’s next and whether there is an incentive to develop higher hashrate miners beyond 7nm chips Yangxin said:

“From a technical point of view, there is no end to the development of technology. However, in the short run, the driving force behind the development of next-gen miners beyond 7nm chips is slowing down due to physical limitations.

With the nm size shrinking quantum effects, among other new challenges, come into play. It is promising that TSMC (Taiwan Semiconductor Manufacturing Company) is already in the process of building 5nm chips. We will continue to follow the development of this technology but it is still early days.  

It takes several iterations to create new miners based on the next generation semiconductor process. The solutions to the challenges of nanometer scale mass production require more investment and further research and development.

Considering the rapid pace of development in this area in the past few years, the industry would soon have to find what the next generation would be. For the near future, 7nm would remain the most preferred in terms of performance and economics.”

The new Antminer 17 series will go up for sale on Bitmain’s official website on 9 April 2019.

Bitmain Releases New Equihash Miner Antminer Z11

Utilizing Bitmain’s all-new ASICs, the Z11 packs three times more hashing power than its predecessor.

HONG KONG, Mar. 19, 2019 – Bitmain, world’s top 10 and China’s second largest fabless chipmaker, officially released the Antminer Z11 today.

The Antminer Z11 is designed by Bitmain to virtually mine cryptocurrencies such as Zcash, which are based on the Equihash algorithm. It is by far the leading model by performance to mine such cryptocurrencies. The new Antminer is now pre-selling on Bitmain’s official website and will start shipping shortly.  

The Antminer Z11 offers a hashing power of 135 KSol/s, which is three times more powerful than that of the Antminer Z9, Bitmain’s previous Equihash miner. With a newly designed internal circuit structure, the Z11 also has a power-efficiency of 10.50 J/KSol, saving 60% of electricity cost compared to the Z9.

The Antminer Z11 uses Bitmain’s latest proprietary 12nm chip, which is made using advanced Bare Die molding technology for better heat dissipation. Even though the Antminer Z11 packs in three times more hashing power than the Antminer Z9, at 5.4 kg, it weighs slightly less than the Z9.

Antminer Firmware Update -April 2017

There is a new controversy regarding a feature in the firmware of Bitmain’s Antminer series of Bitcoin miners which allegedly claims that Bitmain can remotely shut down Antminers. This feature was designed and coded by the same team that is responsible for the firmware of Antminers. As the firmware has always been open-source, the feature was never intended to be malicious.

We need to clarify the intention of having this feature. We planned to add this feature to the code to empower customers to control their miners which often times can be hosted outside their premises. This was after more than one incident of miners being stolen from a mining farm or being hijacked by the operator of the mining farm:

  1. In 2014, around 1,000 Antminers were withheld from the owner by a hosting service provider in Shenyang, China.
  2. In 2015, around 2,000 units of Antminers were withheld from the owner by a hosting service provider in Georgia.
  3. In 2017, Bitmain’s own miners were withheld and sold without its consent in Canada.

This feature was intended to allow the owners of Antminer to remotely shut down their miners that may have been stolen or hijacked by their hosting service provider, and to also provide law enforcement agencies with more tracking information in such cases. We never intended to use this feature on any Antminer without authorization from its owner. This is similar to the remote erase or shutdown feature provided by most famous smartphone manufacturers.

However, this feature was never completed. We started to develop this feature since Antminer S7 and wanted to finish its development on the Antminer S9. We hoped to make it a useful feature that we could advertise to our customers. But, due to some technical problems, we were unable to finish the development of this feature and shut down the testing server in December 2016.  It is a bug to leave the code there before the feature is fully complete and acknowledged to the users. This bug has now been pointed out in context of Bitcoin’s scaling roadmap debate and has caused considerable misunderstandings within the Bitcoin community. We apologize for this.

Following are the models affected by this bug:

  • Antminer S9
  • Antminer R4
  • Antminer T9
  • Antminer L3
  • Antminer L3+

Since MITM and DNS hijacks can exploit this bug we would like to apologize to our customers for a degraded level of security caused by this. We should also note that the existing stratum protocol is vulnerable to MITM and DNS hijacks, and that the mining industry needs to work together on design of the next generation mining protocol.

Moving on, we have released the new updated source-code on GitHub and new firmware on our website which removes this bug. We recommend all Antminer owners to upgrade their firmware to the updated firmware from the list below and strongly advise to not download any firmware provided by a third-party which can lead to unexpected outcomes in function and can also be potential phishing attacks.

Antminer S9 firmware
Antminer T9 firmware
Antminer R4 firmware
Antminer L3 firmware
Antminer L3+ firmware

Source code on GitHub

Source-code for Antminer S9, T9 and R4: https://github.com/bitmaintech/bmminer-mix
Source-code for Antminer L3 and L3+: https://github.com/bitmaintech/setup-A8 which includes https://github.com/bitmaintech/ltc_frimware inside.

Alternatively, we advise owners of mining farms that run Antminers to set the DNS record on their routers of auth.minerlink.com to 127.0.0.1 in the /etc/hosts file by the following method:

1. Use ssh to login to the miner
2. Run command:   echo “127.0.0.1     auth.minerlink.com” >> /etc/hosts
3. Run command:   sync

 

The controversy around this code has brought our attention to improve the design in order to address vulnerabilities that were pointed out by the community recently. For this, we thank the community for pointing out bugs and contributing to our open-source codebase. We would also like to take this opportunity to express our solidified belief in the open source community and express our renewed commitment to improving the quality and testing methods of our code.

We will continue the development of this feature to provide a technical protection for mining rig owners to host their miners in remote locations. We will add a switch to this feature, and this switch will be closed by default. Customers will be able to set up and configure their own authentication server. Before we finish this development, such a code will not be in the firmware we release from now on.---------------------
