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.

To preserve the Zcash community’s values around security, reliability and accessibility, Bitmain had previously Tweeted real-time updates to ensure more transparency and will continue to provide shipping updates of the first batch of the Antminer Z11. These commitments to transparency will continue to provide the Zcash foundation and community with the security, reliability and accessibility they desire of manufacturers.

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.---------------------

Beware of the Phishing Website Bifmaintech.com

phishing website bifmaintechWe were today informed by a concerned Bitmain fan that a website with a domain (www.bifmaintech.com) similar to that of Bitmain’s official website www.bitmaintech.com is mirroring our original website. He found this website through a Reddit post announcing release of the Antminer R4.

phishing website bifmaintech

Interestingly the Reddit post links to another article on a tech news’ website called TechUpgrade.com It may be good for our advertisement but the article is filled with phishing links and inaccurate information.  To lure customers into buying from their phishing website, the website displays an unbelievably low price of $995 and also includes the APW5 in that “$995 package”.

We have reported the issue to the website on their “Contact Us” page but not sure if the message went through because it doesn’t show any confirmation message.

We hope that no Bitmain fan or anyone is tricked into paying on this website.---------------------

Batch 12 and Batch 13 of the Antminer S9

Batch 10 and batch 11 of the Antminer S9 sold out in roughly 10 hours of launch. They were considerably stocked and so we were overwhelmed by the response again.

Unfortunately many Bitmain fans and miners missed their chance to order before the two batches sold out.

So we have good news for everyone: we are going to release two new batches!

Batch 12 and batch 13 can deliver a hashrate of 11.85TH/s and 12.93TH/s, respectively.

They will be available to order after 2300 hours (Beijing time, GMT +8) tomorrow (18 August 2016).

We suggest everybody to confirm their order here (https://goo.gl/w3G2NB) for batch 12 or here (https://goo.gl/jpvZU3) for batch 13 before they sell out.

We wish all a very happy mining experience with Bitmain.---------------------
