The National Information Security Vulnerability Sharing Platform (CNVD) released a security announcement titled "Analysis and Repair Suggestions for PHP Remote Code Execution Vulnerability," in which it supports affected users to closely monitor official information, download and update to the latest version through official channels. Users who are temporarily unable to update can take measures to reduce certain attack vectors, mitigate vulnerability threats, and continuously monitor for abnormal PHP process exits, abnormal system command calls, unfamiliar process creations, and abnormal file writes, while retaining logs for traceability analysis.In its protection recommendations, CNVD stated that information system operating units should further strengthen security protection, comprehensively sort out their network assets, and reduce the public exposure of information systems according to the principle of not connecting to the internet unless necessary. Operating units that are currently unable to repair should take temporary response measures such as network isolation, network access restrictions, and taking unnecessary business systems offline.

Paranoid developer Ignotus Nemo proposed a recursive aggregation scheme for EIP-8288 on the Ethereum research forum, suggesting support for various approved proof sizes to allow smaller proofs for small-scale aggregation. He implemented heterogeneous recursion in the Paranoid system, which has been running both large and small state transition proofs on the public mainnet.The scheme uses a limited set of authenticated validator libraries, processing cross-class delayed validation through independent accumulator channels for each class to ensure the correctness of matrix claims in the recursive steps. When applying this mechanism to EIP-8288, discussions are needed on how to merge subclass libraries, handle dependencies, and address semantic compatibility issues between program identities and validator classes. EIP-8288 was proposed by Vitalik Buterin and Thomas Coratger in June 2026, primarily addressing the issues of large post-quantum signatures and STARK proof sizes, as well as high on-chain verification costs.

Uniswap Labs announced that Aggregator Hooks are now live, enabling aggregation functionality in Uniswap v4. This mechanism wraps external liquidity sources into v4 pools through Hooks, allowing any routing to treat them as Uniswap pools. It is currently available on the Uniswap web interface and API, covering Ethereum mainnet, Base, and Robinhood Chain, with more networks to be integrated soon.On the first day of launch, it supports seven external sources, including Curve, Fluid, and PancakeSwap. Each block routing will pull the latest quotes from the integrated sources, constructing the optimal path between the Uniswap pool and external sources during exchanges, and completing settlements within a single transaction without the need for additional authorization. Uniswap stated that most on-chain liquidity is already on Uniswap, but new liquidity may still appear in other places. After external sources are incorporated into v4, exchanges routed through them will incur protocol fees, contributing to UNI burn.

CoinDCX released further clarification regarding the on-chain activities of the TQKJQ wallet, stating that after the security incident in July 2025, the affected wallet addresses have been deactivated, but some users are still depositing funds to the old addresses. The platform's original periodic fund collection process was ineffective for a period of time, and the related issues were discovered this morning, resulting in some operational losses, which will be borne by CoinDCX.CoinDCX stated that despite some users depositing funds to the deactivated addresses, the relevant user accounts have still received the corresponding credits. The platform claims that customer assets continue to be stored in independent cold wallets, and the currently active wallets and user addresses have not been affected, with the platform's trading operations running normally. CoinDCX also reminds users to verify the latest deposit addresses only through the official app or website to avoid transferring funds to deactivated addresses.Previously, on-chain detective ZachXBT had questioned why the deposit address TQKJQ was still in use for about 10 months after the security incident, with approximately $15.8 million of user deposits unaccounted for.

According to "Reading Plus," the short drama application Hongguo Short Drama App, owned by ByteDance, has launched "Xiaoguo AI." This feature has undergone a period of gray testing and is now officially online, relying on the Doubao large model. It is labeled as Hongguo AI BOT within the app and is positioned as an AI assistant for finding short dramas, providing series search and recommendations. The report states that this is the first time Hongguo has integrated conversational AI into the user-end drama search scenario, beyond AI short drama production.According to practical tests by "Reading Plus," the main entry point is located in the app's search bar. Clicking it leads to the conversation page, and users can also ask questions in the comment section by @XiaoguoAI. The page features quick questions, such as "What short dramas are everyone watching?" and "What are the differences between male-oriented and female-oriented short dramas?" When users input keywords, it returns a list of suggestions, a trending short drama list, and series popularity. The AI responses can pop up short drama cards with play buttons, which redirect to the viewing page when clicked.This tool relies on generative models and search plugins to return information such as titles, plot summaries, poster stills, reputation ratings, and playback channels based on keywords and viewing preferences. From user feedback, it can also record update requests and push notifications when new seasons of followed series are available for reservation.

Galaxy Research Research Director Alex Thorn stated that since the second half of October, Bitcoin returns have been primarily driven by the Asian trading session, while the European trading session has dragged down overall performance.The chart he shared shows that as of October 20, calculated from October 1, the cumulative return of Bitcoin during the Asian trading session was 3.9%, 1.1% during the U.S. trading session, and -5.5% during the European trading session; the return for buying and holding all day during the same period was -0.7%.

Glassnode published that the key price level for Bitcoin in the fourth quarter is still being held. The institution previously pointed out in the "Charting Crypto" report with Colin Basco and the Coinbase Institutional team that BTC faces resistance in the range of $87,000 to $87,800. Since then, the Bitcoin price has been blocked in that range and continues to oscillate and consolidate below.Glassnode believes that if Bitcoin breaks through the current consolidation range, the market may experience significant volatility, but there is still a large area of selling pressure around $90,000 above.

Hunter Biden, son of Biden, stated that over 12% of the total supply of LAPTOP tokens has been permanently destroyed. Among them, 30% of LAPTOP tokens are linked to real-world prediction results: if the relevant predictions come true, the corresponding tokens will be destroyed; if the predictions are not realized, the tokens will be donated to charity.This destruction was triggered by predictions related to the Nobel Peace Prize and also includes all unclaimed airdrop tokens.

Cryptocurrency market maker Wintermute today updated its market report, stating that multiple events such as the Federal Reserve's interest rate decision, the U.S. midterm elections, and third-quarter earnings reports are approaching, and the current narrow trading range of Bitcoin may soon be broken. If Bitcoin breaks above $87,000, it may confirm an upward breakout; if it effectively falls below $82,500, the price could further dip to just above $70,000.On the macro front, the overall CPI in the U.S. rose from 3.4% in August to 3.7%, with core CPI increasing by 0.3% month-on-month, higher than the market expectation of 0.2%, intensifying concerns about energy prices transmitting to core inflation. Wintermute pointed out that the recent rise in U.S. Treasury yields reflects more of a withdrawal of funds from crowded AI growth stock trades rather than an improvement in inflation expectations. The market currently expects the Federal Reserve to maintain interest rates at its meeting on October 28, but if hawkish signals are released, it may strengthen expectations for a rate hike in December, pushing up U.S. Treasury yields and suppressing risk assets.Internally, the cryptocurrency market shows a trend of funds concentrating on mainstream coins. The report indicates that Bitcoin's weekly decline was 1.99%, the Nasdaq index fell by 5.52%, and altcoins overall dropped by 5.69%. Funds continue to flow into BTC and ETH while withdrawing from most altcoins, with high beta and small-cap tokens facing more significant pressure. Wintermute believes that the current risk-reward ratio for mainstream coins is relatively more attractive, and a broad rally in altcoins may need to wait for Bitcoin to strengthen further.Wintermute also noted that the current implied volatility is relatively low, and with the Federal Reserve's decision and midterm elections approaching, the market may be underestimating the risk of subsequent volatility. The Federal Reserve's decision on October 28 will be a key catalyst in the near term, and the performance of AI-related companies' earnings reports will also influence the market's judgment on computing power investments, financing costs, and business models.
