Zilliqa Ledger application exposes serious vulnerability, signing 5 native transactions may leak private keys

Zilliqa stated that there is a serious random number generation vulnerability in the Zilliqa Ledger application, affecting the Schnorr signatures of native non-EVM Zilliqa transactions. Attackers can recover the signer's private key from the biased temporary random numbers using only publicly available on-chain data.Any account that has signed and broadcasted about 5 or more native transactions through the Zilliqa Ledger application should be considered compromised. Since the related signatures are permanently recorded on the chain, subsequent updates to the application cannot eliminate the risk, and the affected private keys must be deactivated. EVM transactions and development tools such as zilliqa-js, gozilliqa-sdk, and pyzil are not affected.The vulnerability arises from the application selecting the wrong 32 bytes when copying the random number, retaining 8 bytes of zero padding and losing 8 bytes of entropy, resulting in each random number having a maximum of 64 bits fixed to zero. Attackers can use 5 or more affected signatures to recover the private key within seconds using ordinary hardware. Zilliqa observed suspected active exploitation on July 19 and confirmed the root cause on July 21.Zilliqa has suspended native transactions to prevent further loss of funds and is preparing a revised application with Ledger. However, the revised version cannot protect the exposed keys, and affected users should not transfer assets on their own but wait for the official announcement of a coordinated disposal plan.

Changxin Technology's global DRAM market share reaches 9%, with the 15% "survival line" being key to entering the top tier

According to the latest report released by market research firm Counterpoint Research, Chinese memory chip giant Changxin Technology (CXMT) currently holds a 9% share of the global DRAM market (by bit shipments), and this figure is expected to rise to 11% by 2028 (with a revenue share of 9%). The report indicates that Changxin Technology is transitioning from an industry "challenger" to a "strategic player," with a long-term goal of achieving a bit shipment share of 20% and a revenue share of 15% by 2035.However, the report emphasizes that to truly establish a foothold in the global memory market and join the ranks of the "big three DRAM manufacturers," Changxin Technology must cross the global market share threshold of 15% to 17% (about one-sixth). Historical experience shows that in 2008, Taiwanese DRAM manufacturers could not secure the massive funding needed for the research and development of the next generation of fabs after their market share fell below 15%, ultimately causing their market share to plummet to the edge of 3%. Therefore, the 15% share is seen as the core survival line for Changxin Technology to ensure sustainable development and self-sustaining capabilities in the medium to long term.To cross this threshold, Changxin Technology is leveraging newly raised funds to accelerate capacity expansion, planning to double its capacity by 2030 and triple it by 2035. Although facing external challenges such as U.S. equipment export controls and global supply chain access, analysts believe these restrictions may instead act as catalysts, forcing Changxin Technology to accelerate independent innovation in cutting-edge technologies such as Vertical Channel Transistors (VCT) and Wafer-on-Wafer bonding, thereby narrowing the gap with industry leaders.

Wintermute: Bitcoin shows "bearish but not falling" bottoming characteristics, key resistance level at $67,250

Wintermute released a market analysis stating that under multiple geopolitical shocks such as the U.S. airstrikes on Iran and the closure of the Strait of Hormuz, Bitcoin has still maintained the critical support level of $62,000, showing strong resilience in the market.Last week, as U.S.-Iran negotiations were paused due to related issues, Iran attacked commercial vessels, and the U.S. launched a new round of airstrikes. Tehran announced the indefinite closure of the Strait of Hormuz, leading to a significant rise in international oil prices, with Brent crude oil seeing a weekly increase of 6.3%, and the yield on 10-year U.S. Treasuries rising to 4.57%. The market has readjusted the probability of a Fed rate hike in September to about 61%, and the U.S. CPI data to be released this week will be a key indicator affecting expectations for the July FOMC meeting.In the cryptocurrency market, Bitcoin has maintained a stable trend despite facing consecutive geopolitical risk events, holding the $62,000 area after a minimum pullback and gradually rising to around $64,000. Ethereum performed even stronger, with prices nearing $1,805.Meanwhile, the eight-week trend of ETF fund outflows has finally ended, with Bitcoin and Ethereum-related products recording a total inflow of about $282 million last week. Although the weekly inflow is still insufficient to confirm a trend reversal, combined with the recent continuous accumulation by whales and the market's weakened reaction to negative news, marginal selling pressure is easing, and the market may be forming a phase bottom.Additionally, the market's reaction to Strategy selling Bitcoin has been muted, contrasting sharply with two months ago when the sale of just 32 BTC triggered a sell-off, indicating that investor concerns about potential selling pressure have significantly decreased.Currently, Bitcoin has shown a "not falling on bad news" bottoming characteristic, but the market still needs to wait for further confirmation. Key factors going forward include the performance of U.S. CPI, whether ETF funds can continue to flow in, and the developments in the Strait of Hormuz situation. If inflation data cools, fund flows continue to improve, and progress is made on the CLARITY Act, Bitcoin is expected to challenge the key resistance level of $67,250; conversely, if oil prices continue to rise and macro pressures intensify, the $60,000 support may face another test.

Key progress in the Qian Zhiming 60,000 Bitcoin case: Lantian Ge Rui enters through the litigation administrator, and the dispute over the applicability of Chinese and British law is in direct confrontation

According to Caixin, the case involving 60,000 bitcoins belonging to Qian Zhimin held a three-day hearing from July 7 to 9, 2026. Blue Sky Ge Rui Company officially joined the battle for bitcoin rights through the litigation administrator. The bitcoin dispute has transformed from a "two-party confrontation" into a "three-party competition": 1. The UK prosecution (DPP) claims that the assets should be recovered by the state; 2. The Chinese victims assert that they have property rights to the bitcoins that can be traced and have significantly appreciated in value; 3. The litigation administrator representing Blue Sky Ge Rui Company argues that the bitcoins are substitute assets formed after Qian Zhimin misappropriated company funds.It is reported that the estimated value of the bitcoins involved in the case is about 427,000 yuan each as of July this year, a 152-fold increase from the purchase price when Qian Zhimin acquired them in 2014 (2,815 yuan each). If the applicant can successfully assert their property rights to the relevant bitcoin assets, the amount they can recover will not be limited to the original investment loss but can also extend to the appreciation gains of the bitcoins. The litigation administrator representing Blue Sky Ge Rui Company believes that the bitcoins in question are essentially transformed from misappropriated company property, and the company has the right to trace them and assert property rights.Meanwhile, the Director of the UK Crown Prosecution Service (DPP) continues to insist that Chinese law should apply, while the leading law firm representing individual victims has proposed four complementary legal arguments to avoid the victims' claims being entirely dismissed due to any single legal pathway: 1. Bitcoin in the UK should be governed by UK law; 2. The investment contract is a scam, and upon cancellation, the rights revert to the victims; 3. The tracing mechanisms under POCA Sections 305 and 306 should also apply to the victims; 4. A "mixed structure" should break the binary choice between Chinese and UK law.

first_img Key components surge in price, PC brands accelerate the introduction of domestic storage from Changchun and Changxin to reduce costs

According to the Industrial and Commercial Times, due to the soaring prices of key components such as memory and SSDs, the cost pressure for configuring high-capacity storage in mainstream laptops has greatly increased. Cost-effective mainland Chinese memory and storage components are gradually penetrating the PC supply chain, with brands such as Lenovo, ASUS, MSI, Gigabyte, Acer, and even the American brand Apple accelerating the certification, introduction, or platform tuning of related products.The report pointed out that Lenovo has expanded its use of mainland components this year, and recently flagship laptop models equipped with Yangtze Memory Technologies (YMTC) SSDs have appeared on North American cross-border e-commerce platforms. The American brand Apple is also reported to be negotiating with the U.S. government to procure Changxin Memory Technologies (CXMT) memory to cope with the rising prices. In terms of Taiwanese board manufacturers, MSI recently announced that it is the first to complete the verification and tuning of Changxin Memory DDR5 chips on the AMD platform at DDR5-8000+, while Gigabyte has also adopted Changxin Memory chips in some motherboard models. ASUS and Acer have introduced memory modules from mainland manufacturers such as BIWIN through their own brand memory certification or OEM models.Industry analysts believe that although the short-term imbalance in supply and demand for storage has prompted non-mainland brands to accelerate related certifications, due to the limited production capacity of mainland manufacturers, brand Taiwanese manufacturers still emphasize that Korean original manufacturers with long-term contracts remain the main supply partners at present.
