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.

Suspected Malicious Activity Drains AnySwap Tokens via Multichain ExecutorAccording to an on-chain sleuth known as Spreek, a person is using the Multichain Executor to drain tokens associated with the AnySwap bridging protocol.Multichain is a cross-chain routing network, established and maintained by a Chinese developer team. It supports in excess of 25 blockchains and more than 1,100 tokens.Photo by Marek Piwnicki on Unsplash$100 million outflowThis revelation comes after abnormal outflows of over $100 million from Multichain bridges on July 7, which were flagged by the Multichain team. Spreek’s report via Twitter on July 10 states that the Multichain Executor address has been draining anyToken addresses across multiple chains and transferring them to a new externally owned account (EOA).Evidence provided in the report includes an Ethereum transaction, 0x53ede4462d90978b992b0a88727de19afe4e96f0374aa1a221b8ff65fda5a6fe, which called the “anySwapFeeTo” method on the Multichain Router: V4 contract. This transaction resulted in approximately $15,275.90 worth of anyDAI being minted on Ethereum, sent to the Multichain Executor, burned, and exchanged for the underlying DAI backing the asset.The funds from these transactions were sent to the following address:0x1eed63efba5f81d95bfe37d82c8e736b974f477b. Similarly, on the BNB Smart Chain (BSC), the Multichain Executor used the anySwapFeeTo function to convert $208,997 worth of anyUSDC into Binance-pegged USDC and sent them to the same address. Additionally, 50.80 anyBTC, equivalent to $39,251.43 at the time, was converted into Binance-pegged Bitcoin and sent to the address.In total, approximately $263,524.33 worth of tokens were sent to this address through the anySwapFeeTo method. Spreek suggests that this behavior could be part of the protocol’s normal functioning. However, a different account engaged in similar activity the day before and ultimately sold the drained tokens, indicating malicious intent.Potential exploitSpreek theorizes that the attacker may be exploiting the anySwapFeeTo function by setting fees to an arbitrarily large amount, allowing them to drain users’ funds. The function apparently permits setting any value, enabling the address to choose the total value of the token held in that anyToken.The Multichain incident has puzzled blockchain analysts, as it remains unclear whether it resulted from an exploit or if it was simply large token-holders moving their funds between networks. The mystery began on July 7 when over $100 million worth of tokens were withdrawn from the Ethereum side of Multichain’s bridges and transferred to wallet addresses with no prior transactions. This represented the majority of funds held on each bridge.Hack or rug pullThe Multichain team labeled these withdrawals as “abnormal” and advised users to stop using the protocol. However, they have not disclosed the source or nature of the anomaly. In response to the incident, stablecoin issuers Circle and Tether froze some of the addresses involved in the suspicious transactions. Chainanalysis, a blockchain analytics firm, has commented that the incident appears more like a hack or rug pull rather than a migration.Adding to the complexity, the Multichain team has reported that their CEO is missing, and they have shut down certain bridges due to losing access to some of the network’s multi-party computation network servers. There have been various concerns relative to Multichain since May. The situation continues to evolve, with ongoing investigations and efforts to mitigate any potential damage caused by the suspected malicious activity.

Suspects emerge in Taiwan in ongoing JPEX scandal falloutIn the ongoing saga surrounding the collapse of Dubai-headquartered cryptocurrency exchange JPEX, Taiwanese prosecutors have identified new suspects, marking a significant development in the case.The Taipei District Prosecutors Office (TDPO) has requested the custody of Chang Tung-ying, chief partner at JPEX’s Taiwan office, over allegations of fraud. That’s according to a report by local TV channel TVBS News on Thursday.Photo by Ricky Zeng on UnsplashMoney laundering and Banking Act violationsThis latest development brings a new twist to the scandal, which has largely been playing out in the Chinese territory of Hong Kong. The TDPO reportedly conducted searches at nine locations linked to the JPEX investigation. Chang, along with three other individuals, including JPEX lecturer Shih Yu-sheng (also known as Shi Yu), was summoned by the authorities. Chang and Shih are being investigated for violations of the Banking Act and the Money Laundering Control Act.During the investigation, JPEX salespersons Liu Chien-fu and Niu Keng-sheng were released, with Liu being granted bail of 50,000 New Taiwan dollars ($1,550). Niu, the registered person in charge of JPEX Taiwan, was released after questioning.Celebrity promoter focusThe report also revealed that Nine Chen, a Taiwanese celebrity and singer who previously served as a brand ambassador for JPEX, was summoned by prosecutors. He has cooperated with law enforcement in the role of a witness to the alleged fraud who has testified to illicit activity carried out by the platform. However, it is now understood that recent events have developed such that Chen is now being treated as a defendant.This action resonates with actions taken by the authorities in Hong Kong some weeks ago in the earlier stages of investigation into this affair. In September, one of the first actions taken by Hong Kong law enforcement was the arrest and detention of social media influencer and former lawyer Joseph Lam, known to followers as “Jolamchok” on the Instagram platform.Alleged liquidity crisisJPEX, once a successful crypto exchange, abruptly halted some services in mid-September, citing a liquidity crisis triggered by alleged “unfair treatment” from institutions in Hong Kong. The sudden implosion led to accusations of misleading investors regarding the application for a crypto trading license and other issues.The scandal surrounding JPEX has escalated into a major industry concern, prompting investigations by Hong Kong authorities. Over 2,000 complaints from JPEX users, reporting losses of nearly $180 million, have triggered significant regulatory attention.As investigations progressed in Hong Kong, the authorities took the decision to block access to the platform, with the platform responding by advising customers to circumvent this restriction through the use of a virtual private network (VPN).As of September 25, law enforcement has arrested at least 11 alleged suspects in the JPEX case, while the alleged masterminds remain at large. At that time, Hong Kong’s Securities and Futures Commission (SFC) pledged to renew its efforts to combat unregulated crypto platforms in Hong Kong.A survey conducted by the Hong Kong University of Science and Technology (HKUST) business school has indicated that the affair has had a negative impact on public sentiment towards crypto more recently.
