German Chancellor Friedrich Merz stated at the Invest in Germany Summit in Berlin that Germany hopes to become a leader in integrating AI in key industries, specifically naming manufacturing, machinery, and the automotive industry. He urged small and medium-sized enterprises to utilize existing data, saying, "Please open the door for AI to use your data." He claimed this is Germany's true secret and real advantage.NVIDIA announced at the summit that it would increase its investment in the European AI sector, planning to support four German startups: Agile Robots, Avelios Medical, Mirelo, and Reflex Aerospace. This is part of its nearly $10 billion commitment to Europe for investing in companies, universities, and research institutions; NVIDIA did not disclose the specific amounts for these four investments. Agile Robots develops AI robots for manufacturing, logistics, and healthcare, Avelios Medical creates hospital management software, Mirelo develops AI models for generating audio from video, and Reflex Aerospace designs and manufactures satellites.NVIDIA CEO Jensen Huang stated that AI will only enhance, not replace, Germany's capabilities in manufacturing, mathematics, and science, and called AI a new tool for businesses. NVIDIA is expanding its cooperation with the German federal government and the Industry 4.0 Platform, with both parties signing a joint declaration of intent to promote industrial application AI models. On the same day, Siemens announced a new AI program in collaboration with NVIDIA at its Erlangen plant, stating that the related technology could reduce engineering work in production preparation by up to 85%, and AI production planning could lower costs by up to 20%.

The decentralized perpetual contract trading platform Aster announced that, in light of recent developments related to PAPER and potential market risks, it has adjusted the pre-market perpetual contract for PAPER to a liquidation-only mode and plans to officially delist the contract at 9:45 AM Beijing time on October 20. Aster recommends that users holding open positions proactively close their positions before the delisting, calling this a precautionary measure to manage market risks and maintain trading order.Previously, Papertrade stated that there are currently no plans to allow external transfers of the PAPER token and will adjust short-term trading fees and the token issuance curve. The team believes that the PAPER perpetual contract could make the liquidity pool's solvency a target for short selling, and external short exposure may increase the profit potential for manipulation attacks, as these markets are not controlled by the protocol.Papertrade founder Jez also pointed out that due to the rapid progress of the perpetual contract market, PAPER is currently set to a non-transferable status to avoid potential attack risks and maintain the long-term healthy development of the protocol. Jez emphasized that PAPER represents users' rights to the protocol's earnings, and its long-term value depends on whether Papertrade can continue to attract traders. The team made this risk management choice based on the operational data from the first week after the protocol's launch.

CME Group announced the official launch of Uniswap futures contracts, which are now open for trading, offering two contract sizes and supporting 24/7 trading.

The U.S. Commodity Futures Trading Commission (CFTC) stated in its latest court filing that CME only claims increased competition without reasonably explaining the existence of imminent financial harm, which is insufficient to qualify for a lawsuit challenging its perpetual contract policy. The CFTC pointed out that after the policy adjustment, CME's cryptocurrency futures trading volume has actually increased.In May of this year, the CFTC approved Kalshi's first Bitcoin perpetual contract and stated that it would regulate such products on a case-by-case basis under futures regulations. CME, on the other hand, believes that perpetual contracts do not have an expiration date and should be classified as swaps rather than futures, subject to a different regulatory framework. Last month, the CFTC requested a federal judge to dismiss the case, and this filing further elaborated on its rebuttal to CME's standing in the lawsuit.The CFTC also noted that CME had previously informed investors that it had not heard customer demand for perpetual contracts, and that such products could not replace its existing futures, and that it should not take different positions in court and during earnings calls. TD Cowen policy analyst Jaret Seiberg believes that CME may still have the upper hand regarding its standing in the lawsuit and the argument that the products should be classified as swaps. However, he is concerned that if the perpetual contract market continues to grow during the litigation, it may become more complicated to dismantle this market if CME wins.

According to a report by THE ELEC, Samsung Electro-Mechanics announced on October 19 that it has signed a supply contract for packaging substrates for memory semiconductors with a large global company, amounting to 360.5 billion Korean won. The contract period is from January 1, 2027, to December 31, which is equivalent to 3.2% of the company's consolidated revenue last year.This is the first time Samsung Electro-Mechanics has disclosed a long-term supply contract for packaging substrates. With this addition, the number of long-term supply contracts disclosed by the company this year has increased to seven, with a total amount of approximately 4.3 trillion Korean won.

The Zakura team, which operates the Zcash network, released a technical article stating that they plan to allocate a unique viewing key for each ZEC exchange completed through NEAR Intents, in order to block future quantum computers from exploiting public refund addresses to piece together user payment histories. NEAR Intents supports cross-chain token exchanges, and when users exchange the privacy coin ZEC for USDC, the service will publish a Zcash address for the user on the NEAR public blockchain, which will be used to return any unused ZEC.The Zcash address contains a public key generated by the wallet's viewing key, which cannot be reverse-engineered by ordinary computers, but large quantum computers running Shor's algorithm could theoretically deduce the key from the address. Zcash wallets can generate multiple seemingly unrelated addresses, but they typically share the same viewing key. Once an attacker cracks it, they can associate all payments received by the account and read the amounts and notes. Zakura's solution allocates a unique viewing key for each exchange, while the spending key remains in the user's main account. Even if the future refund address is compromised, the attacker would only be able to see payments related to that specific exchange.This design also addresses a practical issue: wallets conducting hundreds of exchanges would generate hundreds of keys, requiring each key to scan the entire Zcash chain during backup recovery. Zakura's solution is a privately queryable database that uses private information retrieval technology, so when the wallet inquires about the refund destination, the database will not know the address being queried. Zakura claims that wallets built on its open-source library (including Vizor) will be able to add this feature in the coming weeks, and hardware wallets will follow after firmware support, ahead of the January quantum-resistant payment target set by Zcash developers this month.

The trading execution platform Tread.fi CEO DYJ published an analysis of the flash crash of AI concept stocks' perpetual contracts in the US stock market early in the morning, stating that the sell-off began at Binance. A trader liquidated approximately 2 million dollars of SanDisk long positions, triggering a sharp decline in other markets due to the thin depth of the order book.According to the transaction timeline listed, a large amount of active selling first appeared on SNDK at Binance, with a transaction amount of about 407,000 dollars in the first second, followed by about 1,030,000 dollars in the next second, and MU also began to see selling in the same second. Hyperliquid then saw sweeping orders, with about 10 addresses submitting IOC sell orders concentrated on SNDK, SOXL, DRAM, SKHX, SKHY, and MU within 1.8 seconds, followed by a second round of synchronized selling. These orders were all used to open new short positions, rather than just reducing positions.In the minute of the first concentrated selling, the transaction amounts for SNDK and MU on Binance were approximately 21.9 million dollars and 5.1 million dollars, respectively, while the corresponding transaction amounts on Trade.xyz were about 3.1 million dollars and 300,000 dollars. The transaction amount for MU on Hyperliquid subsequently expanded to 10.8 million dollars and 9.5 million dollars within the next two minutes, which DYJ attributed to chain liquidation.

According to CoinDesk, during the market closure on Saturday, leveraged bets linked to chip stocks and semiconductor funds were liquidated for nearly $52 million within 10 minutes. According to CoinGlass data, approximately $51.6 million in chip stocks and semiconductor fund-related positions were forcibly closed between 21:22 and 21:32 UTC, of which about $38 million came from bullish bets on rising prices. The sell-off began at Binance and quickly spread to Hyperliquid within seconds.The SOXL contract, which is three times long on chip stocks, suffered the largest loss, approximately $12.7 million; contracts for SanDisk and SK Hynix each lost about $10.8 million. According to David Jeong, CEO of trading firm Tread.fi, he placed the first large sell orders for SanDisk and Micron on Binance at 21:21:59 UTC, and less than a second later, the orders impacted Hyperliquid—this platform, launched by Trade XYZ, tracks contracts for stocks, with about 10 addresses establishing short positions on 6 chip-related contracts within 1.8 seconds. In the first minute, Binance processed approximately $21.9 million in SanDisk trades, while Trade XYZ accounted for $3.1 million.Storage chip stocks had already experienced a tumultuous week due to new competition from Chinese chip manufacturer CXMT. With the stock market closed, these contracts had no real stock prices for reference, and traders could only compete against each other; the rules of Trade XYZ allow the platform to set reference prices independently before external stock quotes resume, with relevant quotes returning when U.S. stocks open on Monday.
