China’s Bitmain Makes Plans to Unveil World’s First 1XJ/T Bitcoin MinerBitmain, the leading player in the cryptocurrency mining equipment business, is set to host the upcoming 2023 Global Digital Mining Summit (WDMS 2023) in Hong Kong, using the event as a springboard to launch its latest Bitcoin miner.The Beijing-headquartered mining equipment manufacturer set out its summit and equipment launch plans on Chinese social media platform WeChat on Monday.Photo by Dmitry Demidko on UnsplashIntroducing the ANTMINER S21With the theme “Empower the Bull Market, Mine with Timing,” the summit will aim to assist clients in strategically positioning themselves in the mining sector to reap the rewards of the next crypto bull market. During the event, Bitmain will introduce its latest research and development achievement — the ANTMINER S21 mining machine.The ANTMINER S21 is likely to take its place at the forefront of Bitcoin mining, given that Bitmain’s ANTMINER series has dominated the mining sector in recent years. Bitmain claims that with the S21, it is introducing a miner with unmatched computing power and efficiency, ushering the global mining industry into the 1XJ/T (Joules/Terahash) era.Ever greater efficiencyBitmain has consistently led the industry’s technological innovations, starting with the S9 model, which first broke the 100J/T barrier, to the S19 series with efficiency ratings of 34.5J/T, 29.5J/T, 21.5J/T, and 20.8J/T. The upcoming S21 is expected to continue this track record of ever greater Bitcoin miner efficiency.In addition to technological advancements, Bitmain is using the summit as a mechanism to offer benefits to attendees. The company will launch a customer points system, allowing clients to apply for credit limits for S21 miners based on their points, enabling them to mine first and pay later. Moreover, the points system will facilitate conversion of points into exclusive coupons for the ANTMINER S21.Hong Kong venueHong Kong has been chosen as the venue for this summit and that’s likely by design rather than by coincidence. Over the course of the past twelve months, the Chinese autonomous territory has been making huge strides in its efforts to become a center for blockchain and crypto-related business.In recent months, Hong Kong has announced several supportive blockchain policies, attracting a significant pool of Web3 talent. The summit will also feature keynote speeches from local government officials, indicating the willingness of the local administration to take every opportunity to further Hong Kong’s strategic objective of furthering crypto, blockchain, and Web3 in the city.Bitcoin mining has proven to be ruthless in its drive towards ever greater efficiency. This is playing out mainly on two different fronts. Firstly, in terms of the cost of the energy input. Miners continue to innovate in this area, to the extent that at this point, it’s difficult to remain competitive if an operation is not tapping into an energy source with a near zero input cost. This is being exploited by sourcing energy that is surplus to energy grid requirements, oftentimes renewable energy, that would otherwise be wasted.The second major factor is the efficiency of the miners themselves. Entities that gain early access to the latest generation of miners from Bitmain and other mining equipment manufacturers immediately become more efficient than the other mining outfits that they compete with to unlock Bitcoin mining rewards on the Bitcoin network.

Bank of Korea Conducts Successful CBDC Pilot Test with Financial InstitutionsThe Bank of Korea (BOK) announced yesterday in a press release that its central bank digital currency (CBDC) pilot program operated successfully in a practical setting involving multiple financial institutions.Testing environmentsPreviously, the CBDC system was tested in an isolated cloud environment. In this recent test, the system was installed on the servers of various financial institutions over a five-month period to evaluate its performance.The 1.2 billion KRW ($905,000) project included the participation of six companies, such as Kakao’s Krust Universe, KakaoBank, and KakaoPay, as well as 14 banks and the Korea Financial Telecommunications and Clearings Institute. Kookmin, Shinhan, and Woori were among the participating banks.Four scenariosThe BOK and financial institutions tested the system’s performance under four scenarios: increasing transaction requests per second, increasing the number of active users, reducing the transaction queue size, and adjusting the block generation time ratio.The increase in transaction requests led to a 10% decrease in transactions per second (TPS), from 2,100 TPS to 1,900 TPS, compared to the single cloud environment test. This result is still deemed acceptable, as the highest TPS recorded in the current small payment infrastructure network is 1,200, which occurs on paydays and other high-transaction days.Issues such as slower response times arose with higher transaction request volumes but were resolved by enlarging the transaction queue size and increasing the block formation time proportion in the block generation process. The block generation process involves two stages: block formation, where transactions are recorded, and block validation, where transactions are verified.Greater stabilityThe test demonstrated that transaction errors at individual institutions did not affect others, suggesting that a distributed ledger system offers greater management stability than a centralized system. However, institutional officers cited challenges in problem-solving and communication when using the distributed ledger system.The BOK plans to involve more institutions in ongoing experiments this year, supporting them in testing their smart contracts on the CBDC pilot system.Photo by Bundo Kim on Unsplash

Bitmain Pays Employees Following Salary SuspensionBitmain, the Beijing-based Bitcoin mining equipment manufacturer, has somewhat resolved its cash flow issues, having recently suspended employee salaries in response to ongoing financial struggles and sluggish progress in its mining operations.Photo by Thought Catalog on UnsplashCash flow challengesNews of the payment issue emerged via employee reports online on Monday. The suspension encompassed both performance-based and basic wages, affecting all Bitmain personnel. The dire situation has marked a critical juncture for the ASIC manufacturer, which once held a commanding 70% share of the global Bitcoin mining machine market.Chinese crypto reporter Colin Wu had also outlined the firm’s difficulties on social media. In a subsequent post on X (formerly Twitter), Wu stated:”On the afternoon of October 7, Bitmain has repaid September wages, and stated that it only did not pay the performance salary of some people. It has also been repaid, and the basic salary has been released normally on September 30.”More recent reports by local news media in China indicated that the firm has proceeded to pay part of its staff salaries.Internal conflictsBitmain’s financial woes are not new. The company has been plagued by internal conflicts between its co-founders, Wu Jihan and Zhan Ketuan, resulting in a debilitating power struggle that severely eroded its market dominance. Earlier efforts to restore financial stability included a restructuring of employee compensation in the first quarter of this year. Under this reform, the original fixed salary was divided into a basic salary and a performance-based component linked to rank.Regrettably, these measures have proven insufficient to reverse Bitmain’s fortunes. In a company announcement issued in September 2023, Bitmain acknowledged that its operating cash flow had plunged into negative territory, and the performance of its mining machines fell short of expectations.Consequently, the company suspended employee salaries, with the prospect of resuming payments contingent upon developments after the October 7 holiday.It emerged in April that the firm had been fined for tax code violations in China.Core Scientific dealIn August, Bitmain explored the possibility of acquiring an equity stake in Core Scientific, a prominent North American crypto-mining company, as part of Core Scientific’s bankruptcy restructuring plan. This proposed agreement, pending final documentation and court approval, entails Bitmain acquiring 27,000 S19j XP Bitcoin miners from Core Scientific.The Core Scientific deal represents a potential lifeline for Bitmain. Nevertheless, the suspension of employee salaries underscores the prevailing uncertainty surrounding the company’s future. Whether the completion of the Core Scientific transaction will usher in the much-needed financial turnaround for Bitmain remains uncertain as the company grapples with its ongoing financial challenges.Bitmain’s decision to suspend employee pay highlights the gravity of the situation and the urgency of finding a sustainable solution to its financial woes. The outcome of the Core Scientific deal could determine Bitmain’s fate as it strives to regain its once-dominant position and secure its financial stability. In the meantime, the firm continues to develop the latest generation of Bitcoin mining equipment.
