TSMC accused of multiple infringements may affect the production capacity of 7nm mining machines

The semiconductor industry has been in the news recently. According to DeepTech, semiconductor foundry GlobalFoundries (GF) filed multiple lawsuits in the United States and Germany on August 26, accusing TSMC of infringing 16 GF patents with its semiconductor technology, and hoped that the US trade authorities would issue an import ban to stop the import of TSMC's "infringing" products. Caijing.com Chain Finance found that in the lawsuit list submitted by GF this time, TSMC's alleged infringing technologies covered multiple processes such as 7nm, 10nm, 16nm, and 28nm.

As Bitmain's chip supplier, TSMC is the production capacity guarantee for Ant's 7nm mining machine. According to previous estimates by Caijing.com Chain Finance, it can be roughly estimated that the computing power of Bitmain's new technology in the first and second quarters of 2020 may reach 55 million TH/s-65 million TH/s.

Exclusive! Source: Rumors of central bank digital currency issuance are inaccurate speculation

Sina Finance reported on August 28 that in response to reports that "the central bank will officially launch digital currency in the next few months", a source close to the central bank exclusively responded to Sina Finance that the above content is inaccurate speculation.

In the early hours of Beijing time today, Forbes released a latest report saying that according to informed sources, the People's Bank of China will officially launch digital currency in the next few months, and will initially issue it to seven institutions including Industrial and Commercial Bank of China (5.390, -0.03, -0.55%), China Construction Bank (6.940, -0.01, -0.14%), Bank of China (3.550, -0.02, -0.56%), Agricultural Bank of China (3.410, 0.00, 0.00%), Alibaba, Tencent and UnionPay. According to a former government employee, the central bank's digital currency may be officially launched on November 11 this year. Once this digital currency is launched as scheduled, the People's Bank of China will become the first central bank in the world to officially launch a digital currency.

Sichuan mine flooded, beware of "parallel import mining machines" entering the market

This year's flood season is a mixed blessing for miners. The good news is that the recovery of the secondary market coincides with the flood season in Sichuan, so any model of mining machine will be profitable as long as it can be turned on. The bad news is that Sichuan's climate this year seems to be not "cooperative". First, the rainy season that should have arrived in early May was delayed for more than a month, and then the sudden concentrated rainfall last week caused flash floods in Ganzi, Aba, Liangzhou and other places, affecting the Bitcoin mines in those places.

From the "live broadcast" in the circle of friends, miners after the flash flood were searching for mining machines buried in the soil with their bare hands in a "tidal flat". The disaster situation was reflected in the Bitcoin network's computing power dropped sharply in a short period of time. According to the RHY mine weekly report: the daily Bitcoin computing power dropped from 78EH to 74EH in a short period of time.

The first batch of students from Ant Training Academy graduated, creating the industry's first batch of mining machine maintenance personnel

Recently, the first session of the second-level course of Ant Training Academy founded by Bitmain was successfully completed, and a brilliant report card was handed in: 9 out of 15 students successfully passed the assessment and obtained the two-star mining machine maintenance engineer certificate. This certificate not only provides students with professional skills certification, but also establishes the authoritative certification standard for global mining maintenance qualifications. The smooth implementation of the first training course marks that Bitmain has successfully opened up a standardized and large-scale path to export mining machine maintenance talents to the industry.

Mining Bitcoin and getting altcoins for free: PoW in joint mining

Can Bitcoin mining machines only mine BTC? Of course not, they can also mine BCH or BSV, but just like you can't have your cake and eat it too, you can only choose one of the three.

Joint mining has changed this way of playing. For example, LTC (Litecoin) and DOGE (Dogecoin) are the most classic golden partners of joint mining. After the LTC mining halving in August, the LTC mining pools that support joint mining generally adopt the policy of giving away 2,000 DOGE for every LTC mined. This is very similar to an airdrop, which is basically free.

Joint mining first started with Bitcoin and Namecoin (NMC) in 2011. Today, the number of cryptocurrencies partnered with Bitcoin is enough to form a basketball team. According to incomplete statistics, in addition to Namecoin, Elastos (ELA), Emercoin (EMC), Systemcoin (SYS), and Vcash are the mainstream partners.
