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.

What Every Bitcoiner Should Know About ‘Bitcoin Cash’

In a few days the notorious August 1st is approaching, and it’s likely this day will be remembered for a long time. This week Bitcoin.com discussed the possible scenario of a user activated hard fork called “Bitcoin Cash” as much of the community doesn’t realize this fork will likely still happen despite Segwit2x’s current progress.

Also read: Bitmain’s 24 July Statement about Bitcoin Cash

What is Bitcoin Cash?

Bitcoin Cash is a token that may exist in the near future due to a user-activated hard fork (UAHF) that will bifurcate the Bitcoin blockchain into two branches. The UAHF was initially a contingency plan against the user-activated soft fork (UASF) announced by Bitmain. Since this announcement, at the “Future of Bitcoin” conference a developer named Amaury Séchet revealed the Bitcoin ABC” (Adjustable Blocksize Cap) project and told the audience about the upcoming UAHF.

Following Séchet’s announcement and after Bitcoin ABC’s first client release, the project “Bitcoin Cash” (BCC) was announced. Bitcoin Cash will be pretty much the same as BTC minus a few things, like the Segregated Witness (Segwit) implementation and the Replace-by-Fee (RBF) feature. According to BCC, a few of the biggest differences between BTC and BCC will be three new additions to the bitcoin codebase that include;

  • Block Size Limit Increase – Bitcoin Cash provides an immediate increase of the block size limit to 8MB.
  • Replay and Wipeout Protection – Should two chains persist, Bitcoin Cash minimizes user disruption, and permits safe and peaceful coexistence of the two chains, with replay and wipeout protection.
  • New Transaction Type (a new fix was added, note the “UPDATE” at the end of this post)– As part of the replay protection technology, Bitcoin Cash introduces a new transaction type with additional benefits such as input value signing for improved hardware wallet security, and elimination of the quadratic hashing problem.

Bitcoin Cash will have support from various members of the cryptocurrency industry including miners, exchanges, and clients like Bitcoin ABC, Unlimited, and Classic will also be assisting the project. In addition to this help, Bitcoin Cash developers have added a ‘slow’ mining difficulty reduction algorithm just in case there’s not enough hashrate to support the chain.

Mining and Exchange Support

“We continue to remain committed to supporting the Segwit2x proposal, which has received broad support from Bitcoin industry and community alike — However, due to significant demand from our users, the Bitcoin.com Pool will give mining customers the option of supporting the Bitcoin Cash chain (BCC) with their hashrate, but otherwise Bitcoin.com Pool will by default remain pointed at the chain supporting Segwit2x (BTC).”

Bitcoin.com previously reported on Viabtc adding a BCC futures market to their exchange’s listed coins. The token has been trading at roughly $450-550 over the past 24-hours and reached an all time high of $900 when first released. Two other exchanges, Okcoin via the ‘OKEX’ platform and Livecoin have also announced they will also be listing BCC on their trading platforms. Bitcoin Cash supporters expect more exchanges to follow shortly after the fork is complete.

What Can I do to Obtain Bitcoin Cash?

Again, regardless of Segwit2x’s progress this fork most likely will happen and bitcoiners should be prepared. There are a few days left until August 1 and those looking to acquire Bitcoin Cash should remove their coins from third parties into a wallet they control.

For more information on Bitcoin Cash check out the official announcement here, and the BCC website here.

 

UPDATE, 28 July 2017: According to bitcoincash.org, a change (fix) has been introduced to make “New Transaction Type” to “New Sighash Type”. Following is more info on this new feature:

New SigHash Type – As part of the replay protection technology, Bitcoin Cash introduces a new way of signing transactions. This also brings additional benefits such as input value signing for improved hardware wallet security, and elimination of the quadratic hashing problem.

Regarding “Bitcoin Cash”, ViaBTC and Bitcoin ABC

On 22 July 2017, the Chinese digital currency exchange ViaBTC added support for the trading of a possible new fork of Bitcoin that is being called “Bitcoin Cash” or “BCC”. This fork is based on the idea of UAHF, which is a contingency plan first proposed by Bitmain in April to protect the Bitcoin ecosystem from the threats proposed by the BIP148 fork (aka UASF). Because it is a contingency plan, the UAHF will be implemented by us only if the UASF fork happens and poses an imminent risk to the Bitcoin ecosystem. This has been further described in our blog post.

Bitcoin ABC was proposed at The Future of Bitcoin conference in Netherlands and is a software led by developers who believe in increasing Bitcoin’s blocksize.

The development of UAHF is now led by supporters of Bitcoin’s blocksize increase. Bitmain cannot and does not control their opinions.

Following are some clarifications regarding Bitmain’s current stance:

  1. Bitmain and ViaBTC only share an investment relationship in which ViaBTC operates independently. The founder of ViaBTC has ten times the voting rights as those of the investors of ViaBTC. Therefore, the position of ViaBTC does not represent Bitmain’s stance.
  2. The New York Agreement is a joint effort of the global Bitcoin community. As one of its signatories, Bitmain has actively supported the smooth implementation of Segwit2x and will continue to run the btc1 software on all our mining pools, namely Antpool, BTC.COM pool and ConnectBTC, in the foreseeable future.
  3. We are closely observing the “BCC” movement and do not rule out the possibility of supporting both Segwit2x and BCC.
