Yushu Technology disclosed its third-quarter report for 2026. The company's single-quarter revenue was 666 million yuan, a year-on-year increase of 69.93%; the net profit attributable to the parent company was 113 million yuan, a year-on-year decline of 17.37%, with a nearly 50% decrease compared to the previous quarter.Regarding the profit decline, a relevant person from Yushu Technology's Board Secretary Office stated that it was mainly due to increased R&D investment in computing power and large model directions. This person also mentioned that looking at the longer term, the impact is controllable, and the single quarter only shows a phase change; currently, R&D investment relies on fundraising planning and will not be blindly increased.

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.

The Science and Technology Innovation Board Daily reporter Huang Xinyi exclusively learned that Baidu plans to disclose the research and development progress and results of its world model in the coming days. The world model is one of the popular directions in the current AI field, focusing on modeling and predicting physical environments. It is reported that if this model is used for autonomous driving, it could enhance prediction and decision-making capabilities in complex scenarios, providing support for the large-scale implementation of driverless cars.In the past year or two, Baidu's autonomous driving service, Luobo Kuaipao, has covered 28 cities worldwide and has accumulated a certain scale of real road data. In recent years, Baidu has also been continuously making strategic layouts in the field of embodied intelligence, serving more than 50 key enterprises in the industrial chain, including the Beijing Humanoid Robot Innovation Center, Zhiyuan, Xinghaitu, and Yushu. As for the specific applications of this model and its relationship with Luobo Kuaipao, it is currently unclear, and Baidu has not commented as of the time of publication.

Galaxy Research Director Alex Thorn stated that the 13F holdings report for Bitcoin ETFs is still in the early stages, and most large asset management companies and registered investment advisors (RIA) typically submit their filings just before the November 16 deadline.However, some long-term funds have already increased their holdings in Bitcoin ETFs in the third quarter. Wealth management advisory firm SIGFIG Wealth Management submitted its related filing for the first time, indicating that its clients increased their investments in Bitcoin ETFs by approximately $73 million in the third quarter. A significant portion of the assets managed by the firm comes from retail client accounts at banks such as Wells Fargo, Citizens, Santander, and UBS.

AI Physical Superintelligence (PSI) announced new progress on five long-standing unresolved quantum information problems, leveraging models such as GPT-6 Astra and Claude, and has published papers, proof codes, and verification materials. During the research process, physicists were responsible for guidance and verification, while the relevant models participated in the derivation. The team also had AI Agents from Codex and Claude Code write Lean formal proofs, which were checked by computers to verify the validity of the reasoning.One of the studies demonstrated that in a specific quantum field, quantum entanglement still exists even when two regions are far apart, but once the distance exceeds a certain range, non-local correlations can no longer be tested using the CHSH Bell inequality. Another study proved that a certain type of quantum operation, when performed sufficiently many times, will inevitably destroy entanglement. These five results do not completely resolve the original problems; some conclusions only apply under specific conditions, and there are still unresolved issues.

Bank of America Global Research has included SpaceX (SPCX.O) in its list of preferred stocks in the U.S. market.

ARK Invest's Director of Digital Asset Research, Lorenzo Valente, stated that the number of addresses holding stablecoins has surpassed 300 million for the first time. The Ethereum ecosystem currently accounts for 37% of all stablecoin holding addresses, up from 29% two years ago, with approximately three-quarters coming from L2. He believes that the strategy of expanding adoption through L2 is proving effective and expects tokenized stocks to develop along the same path.Valente also mentioned that if one were to illustrate the dominance of EVM, EVM-compatible chains hold about 94% of stablecoin addresses. It took 8 years for the number of stablecoin holding addresses to reach 300 million, and he anticipates that it could reach 1 billion wallets within 18 months, faster than the existing trend.

According to a report by The Block, Galaxy Research stated that the Bitcoin bear market ended in June, and it is currently an attractive time to buy and hold.The report noted that Bitcoin has closed above the 50-week moving average for five consecutive weeks as of October 18, after being below that average for 44 weeks; the monthly moving volume of Bitcoin in long-term holding wallets has decreased from 67,000 BTC in 2024 to 34,000 BTC in 2026. Galaxy Research Director Alex Thorn also pointed out that if Bitcoin's weekly close falls below the 50-week moving average of $76,540 and fails to recover within a month, this bullish outlook will be challenged.

A researcher successfully cracked the "Steal My Bitcoin" challenge using a PHP vulnerability.The prize for the challenge was 0.02511679 BTC. However, the challenge operators later discovered that the server had saved the wrong wallet key, and ultimately had to manually transfer the prize to the researcher.

Due to the ChainSecurity report revealing compatibility and security issues with EIP-8037 and certain smart contracts, core developers decided last week to postpone the Hoodi testnet upgrade to Glamsterdam. The issues identified so far include: the remaining Gas during transaction execution may increase, leading to underflow in some Gas counting logic and triggering rollbacks, or causing code paths that should not be executed to be triggered, making the transaction appear successful. Additionally, some contracts may underestimate usage due to the inability to correctly calculate Gas consumption during calls.ChainSecurity previously stated that 13 real cases have been identified and they are responsibly disclosing this information to the affected projects. Toni Wahrstätter mentioned that this week they will further investigate the relevant contracts and assess subsequent solutions, which may require collaboration among application developers, core developers, auditors, and node operators. In the worst-case scenario, adjustments to the protocol specifications may be necessary. He reminded application developers and auditors to check the compatibility of contracts with EIP-8037 and EIP-8038 and to report issues in a timely manner.

According to Israeli media TheMarker on October 25, the AI mining project Pearl (PRL) has raised a total of $130 million from the Israeli research laboratory Pearl Research Labs, of which $55 million is equity financing and $75 million is for a GPU infrastructure fund. Investors include Lightspeed, Ribbit, and Square Peg.The report pointed out that the token has increased by approximately 520% within three months since its launch at the end of April, with its circulating market value once rising to $710 million, and its "AI version of Bitcoin" narrative has attracted market attention. However, the report also raised concerns that the company has not fully disclosed the details of the financing and the operational structure of the GPU infrastructure fund, leading to questions about transparency.

Galaxy Research published an analysis stating that over the past three weeks, the Bitcoin network has seen approximately 40 inscriptions composed of random letters each day, which appear to be encrypted text but are not actually cryptographic information. The related address had previously written the U.S. Constitution into the Bitcoin network in May.The research found that after analyzing 562 texts, the frequency of the 26 English letters is almost evenly distributed, which is significantly different from the characteristics of normal English and substitution ciphers; metrics such as word length distribution and frequency of repeated words also indicate that these texts are likely generated by a random letter generator.Galaxy Research refers to the operator as the "Babel Scribe," believing it is more like testing a data publishing tool on the Bitcoin mainnet rather than attempting to convey hidden information. The structure of on-chain transactions, the continuous use of change addresses, and the regularity of publication times all exhibit characteristics of automated scripts. Related activities also include testing texts, random words in different languages, binary data, and the subsequent writing of the U.S. Declaration of Independence.It is estimated that the project has transferred approximately 3.33 million satoshis in total, of which about 24% was used to pay miner fees, while the remaining funds are still held in the related address. Researchers suggest that there is no need to interpret these garbled texts as hidden information.

Research institution Tiger Research researcher Ryan Yoon released the final report of the prediction market series, discussing whether prediction markets have practical utility. The report states that participants bear the judgment results with funds, and prices are updated in real-time with new information, forming probability distributions comparable to traditional polls, expert surveys, and economic forecasts; prediction markets have expanded from sports and election predictions to macroeconomic and geopolitical data infrastructure.The report lists that Google Finance, CNBC, CNN, and The Wall Street Journal have displayed prediction market probabilities, and the parent company of the New York Stock Exchange, Intercontinental Exchange, along with the electronic bond trading platform Tradeweb, distributes relevant data to institutional clients. A working paper from the Federal Reserve Board describes the prediction market Kalshi as a high-frequency, continuously updated benchmark with rich information distribution. The paper states that Kalshi's median and mode predictions for the federal funds rate recorded perfectly the day before the FOMC meeting and significantly outperformed federal funds futures during that period; compared to Bloomberg consensus, it is more accurate for overall CPI and statistically similar for core CPI and unemployment rate.The report also cites research from the Iowa Electronic Markets: in five U.S. presidential elections from 1988 to 2004, and in a comparison of 964 polls, it was more accurate in 74% of cases; the average voting share error one week before the election was 1.5 percentage points, lower than Gallup's final poll of 2.1 percentage points. The report suggests that the platform needs to deepen liquidity to resist manipulation, communicate with regulatory agencies, and position itself as a monitoring tool while maintaining open transparency and data supported by independent research.

The U.S. Department of Commerce will allocate up to $389 million to support chip research and development.

According to CoinDesk, Ben Edgington, the coordinator of the Ethereum rapid finality research direction, along with several researchers, submitted a draft proposing to reduce the transaction finality waiting time from about 16 minutes to about 4 minutes, improving it by approximately four times.The current goal is to push this draft into the formal upgrade proposal process. The core idea of the draft is to separate the original "block selection" and "finality confirmation" mechanisms of validators, allowing finality to progress at a faster pace and facilitating future adoption of quantum-resistant signatures.Faster finality is expected to reduce the costs incurred by cross-chain transfer services due to capital occupation. The Ethereum Foundation's research provides an example: if a service advances about 1 million dollars per hour, under a 16-minute delay, approximately 267,000 dollars would be pending recovery, which could be reduced to about 67,000 dollars after shortening to 4 minutes.

Anthropic opened the research preview of Claude Duet on October 21. This is a standalone application where Claude acts as a proactive agent, prompting users about important matters, completing tasks assigned by users, and continuing to work after the user leaves; it will seek confirmation before taking action on behalf of the user. The product is aimed at professionals and small business owners, providing iOS, Android applications, and claude.ai. The research preview is included in the Pro and Max plans, sharing usage limits with other Claude features. Users need to join a waitlist, starting with Pro and Max users in the United States.Claude Duet is designed around Claude Opus 5.5. It sends a brief summary across connected applications every morning, monitors these applications throughout the day, and only sends messages when attention is needed. It can handle tasks such as scheduling meetings, building dashboards, financial or sales forecasting, prototyping, and web applications. The application utilizes the memory, skills, and connected applications from the Claude account, supports typing or voice communication in the same continuous thread, and is equipped with a virtual machine with a browser, not relying on the user's device to stay powered on. It can use over 6,000 connectors and plugins in the Claude Marketplace, with examples including Gmail, Slack, Intuit QuickBooks, Stripe, Gusto, LinkedIn, Docusign, HubSpot, Canva, and Shopify. Business purchases can use Stripe's Link digital wallet or Shopify's Shop Pay, and it will soon support logging into websites using saved login information from 1Password with user permission.In terms of security, the product follows a trusted agent framework, where hosted agents do not directly see passwords or login tokens, and it has an automatic mode classifier and prompt injection protection; Anthropic has conducted red team and external penetration testing and included it in a public vulnerability bounty program. Before sending messages, making payments, signing documents, or deleting content, it will display the intended action and wait for approval. Securities trading or transfers between accounts are prohibited even if approved. Early versions may misinterpret conversations or misjudge urgency, with core functions focused on work, while personal tasks like booking tickets are weaker. It currently cannot show users its browser and is separate from the main Claude application, with background checks counted towards plan usage.

According to CoinPost, Japan's Minister of Land, Infrastructure, Transport and Tourism, Toshiaki Inoue, stated in the House of Representatives' Land, Infrastructure, Transport and Tourism Committee that he will study the introduction of stablecoins into the consumption tax exemption system for foreign tourists visiting Japan, and mentioned a "refund method" for tax refunds after departure confirmation, stating that he will promote responses from the user's perspective.According to the Japan Tourism Agency, the country's tax exemption system will change to a refund method starting from purchases made on November 1: Tourists will purchase goods at tax-included prices, and within 90 days from the date of purchase, upon departure confirmation by customs, they can then receive the consumption tax refund, which will be handled by the duty-free shop or an entrusted refund agency.
