Recently, in response to user information leaks and supply chain security risks in the hardware wallet industry, KeyPal, a hardware wallet brand under TokenPocket, announced further enhancements to user privacy protection and data security management mechanisms.KeyPal stated that it has not found any security breaches in its system or customer data leaks; this adjustment is a proactive preventive measure based on changes in industry risks.According to the latest plan, KeyPal aims to delete or anonymize unnecessary customer personal information within 15 days after order completion for orders that have confirmed receipt, completed fulfillment, and have no after-sales disputes or other legitimate retention requirements. The security of hardware wallets not only involves private key protection and transaction signing but also includes the protection of personal information generated during the purchase, delivery, and after-sales service processes.

EIP-8450 proposal update, intended to introduce a quantum-resistant public key registration mechanism for Ethereum validators, using a hash-based cryptographic scheme, including leanXMSS keys and VRF tree roots.The update clarifies that the registration and replacement of quantum-resistant keys are authorized by BLS signature keys, and sets a replacement delay of at least one Epoch and a replay protection mechanism; this proposal is currently still in the Draft stage and has not yet been deployed.

Bitget, in collaboration with Reality and Keyring, has released a research report exploring the synergy mechanisms of tokenized stocks, perpetual contracts, and decentralized lending, and evaluating the potential returns and risks of related strategies through simulation calculations. The report points out that the application of tokenized stocks is extending from traditional stock trading to more scenarios such as collateralized lending, asset management, and systematic investment strategies.The research is based on Reality's rToken, combined with stock perpetual contract hedging and on-chain lending mechanisms, to explore stock basis yield strategies. Historical simulation data shows that from December 15, 2025, to October 19, 2026, the annualized net return of the strategy index is approximately 7% and 4% for in-sample and out-of-sample, respectively, with a gross funding cost rate premium of about 11% to 14%. The report also notes that financing costs, transaction execution fees, market liquidity, and risk management are key factors affecting the actual returns of the strategy.It is reported that Bitget and Keyring plan to jointly develop a stock basis index and build an on-chain lending market based on Reality's rToken. Among them, Reality provides exposure to tokenized stock assets, while Keyring is responsible for developing the index methodology and constructing the related lending market. The index aims to capture funding rate and basis yield opportunities by combining rToken holdings with corresponding stock perpetual contract hedging positions, providing new strategic pathways for the application of tokenized stocks in on-chain financial scenarios.

Bloomberg Intelligence released a report on October 28, stating that by 2030, China will be globally leading in 8 out of 17 key industries, including large language models (LLM), which are core to artificial intelligence. The report, led by Francis Chan, assesses that the U.S. and China are moving towards "AI joint leadership," with neither side likely to achieve a comprehensive advantage.The report lists the 8 areas where China is expected to lead: LLM, optical communication transceiver modules, humanoid robots, general commercial vessels, autonomous and connected vehicles, energy storage, green hydrogen, and biopharmaceutical CDMO. On the hardware side, China currently lags in chip design, foundry, memory, and device materials, but the report predicts that by 2030, it will be globally competitive, although complete self-sufficiency remains challenging. The report also notes that the U.S. may maintain a slight edge in model development, while China holds a favorable position in software optimization and low-cost AI implementation.The report also highlights risks: Chinese AI companies face intense price competition, and profitability will need to wait until pricing strategies become more rational. Additionally, trade barriers and export restrictions are more likely to alter the geographical landscape of China's industrial expansion rather than halt it.

Hardware wallet manufacturer Keystone's device verification keys were stolen, halting shipments and destroying 18,835 unsold devices, with 25,964 buyer records leaked.

Market maker Wintermute stated that Bitcoin fell 2.43% last week, marking its third consecutive week of losses, dropping below the support level of $82,500 and testing the $80,000 mark again. Macroeconomically, rising energy prices and inflation concerns are replacing AI financing issues as the main risks in the market. Bitcoin's recent movements are highly correlated with the Nasdaq and AI-related stocks, and ETF fund flows have begun to fluctuate in both directions.Wintermute indicated that the Federal Reserve's interest rate decision and policy statements will be important short-term catalysts. If it fails to hold above $80,000, the next key support level is $76,000; if it effectively breaks below this, the price may further explore the $70,000 range. In the short term, it needs to regain the $82,000 to $82,500 range to have a chance of restoring an upward trend. If the Federal Reserve leans hawkish, the market may reassess the expectations for a rate hike in December, raising investment yields and increasing downward pressure on Bitcoin; if it leaves room for a December decision, it may create conditions for a rebound.The institution stated that before the Federal Reserve's decision and the release of the U.S. third-quarter GDP and September PCE, market directional confidence is insufficient, and caution will be maintained. If the Federal Reserve leans dovish but the PCE is higher than expected, the market may sell off tech stocks due to inflation pressure, dragging down Bitcoin. Wintermute emphasized that it is not clearly bearish at the moment, but remains cautious until Bitcoin regains the $82,500 level.

The hardware wallet OneKey co-founder Yishi stated that in light of recent data breaches and supply chain attacks in the hardware wallet industry, OneKey will further strengthen user privacy protection.OneKey has confirmed through the Shopify API that relevant historical order records and personal information such as names, emails, and shipping addresses have been deleted, and is further investigating other systems and third-party integration services. In the future, it will ensure that personal information related to orders within its control is permanently deleted within 30 days, and plans to gradually migrate its e-commerce business to self-controlled infrastructure to reduce reliance on third-party platforms like Shopify.Yishi also stated that the data retention policies of logistics service providers such as FedEx and UPS are not controlled by OneKey, and it cannot guarantee that all third parties adhere to the same 30-day timeframe.

JUST released an open letter to JST holders and launched the JST 2026 Q3 and October key progress report. The letter pointed out that a total of 1,881,973,007 JST has been repurchased and destroyed over five rounds, accounting for 19.01% of the initial maximum supply, with approximately 118.15 million USD invested in repurchase and destruction. JUST DAO upgraded the JST repurchase and destruction mechanism in October, which will shift to being based on sustainable ecological income, and plans to invest approximately 20.34 million USD of excess funds into repurchase in four phases starting from Q4 2026, while retaining at least 50 million USD as a treasury safety reserve.The report also showed that JustLend's quarter-end TVL remained above 7 billion USD, with approximately 21.24 million transactions in GasFree Q3. As the repurchase funds shift from historical income reserves to sustainable ecological income, the deflationary path of JST and ecological growth are gradually forming a closer linkage.

According to Slow Fog monitoring, Yapeswap suffered an attack, resulting in a loss of approximately $21,900. The root of the incident lies in the WorkersUnion governance mechanism, where the quorum requirement is zero, allowing a proposal that received only about 0.000055% voting support to transfer the feeToSetter authority of YapeFactory to the attacker.The attacker subsequently deployed a malicious Registry contract, causing latestVault() to return a forged vault address, while vaults() still listed the real vault. YapePair accounted for the deposits to be transferred as farm assets, but did not receive redeemable shares, ultimately leading to a loss of funds. This incident involves contracts such as YapeFactory, YapePair, and YapeWrapper.

Cryptocurrency analyst Ali Charts stated that as the U.S. midterm elections on November 3 approach, investors may overlook the recurring phenomenon of Bitcoin pullbacks observed in previous election cycles. He believes that this election may once again be accompanied by significant volatility, and the downside risk is worth noting, with a key focus on the lower price level of $73,000. According to his statistics, during the U.S. midterm election cycles in 2010, 2014, 2018, and 2022, Bitcoin experienced pullbacks of 72%, 65%, 52%, and 27%, respectively.However, he emphasized that correlation does not imply causation; the election itself may not necessarily be the reason for the decline, as these pullbacks are also influenced by the overall market cycle of Bitcoin, liquidity conditions, and investor sentiment. Fourth-quarter returns also exhibit similar characteristics: in 2014, 2018, and 2022, Bitcoin fell by 16.7%, 42.16%, and 14.75% in the fourth quarter, respectively. The only exception was in 2010, when it rose by 391%, but Bitcoin was still in its early development stage at that time. Therefore, in the past four midterm election years, three of those years recorded negative returns in the fourth quarter.Regarding the subsequent trend, Ali Charts indicated that the area around $73,000 is close to the average purchase cost of current short-term Bitcoin holders, which can be used to observe the positions of recent investors entering the market. He pointed out that in an established bull market, Bitcoin often finds support near the cost of short-term holders after experiencing a significant pullback. He believes that if selling pressure accelerates after the election on November 3, pushing Bitcoin back down to around $73,000, that area will become an important position to test whether buyers are still willing to maintain the overall bullish trend. If the price continues to rebound from that area, it will strengthen the bullish judgment; in terms of operations, he will wait for signs of selling pressure exhaustion and renewed demand before considering establishing long positions.
