On October 22, the smart contract security company ChainSecurity announced that the Glamsterdam hard fork on the Ethereum Hoodi testnet has been postponed. Researchers stated that security impacts have been found in existing contracts and identified 13 real cases, and they are currently conducting responsible disclosure with the affected projects. The announcement requests teams to review the contracts, and the Ethereum Foundation is assessing the scope of the impact; the announcement did not name the projects, provide contract addresses, or give an alternative fork date.The related issues involve contracts that continue execution after capturing failed external calls. Under the reviewed gas changes, the failure handler may complete execution, whereas it would previously roll back due to gas exhaustion. The caller can deliberately provide insufficient gas to complete the target operation, but enough to allow the outer contract to record a permanent failure, causing operations that could have been retried to lose their recovery path.The technical disclosure reviews EIP-8037 and EIP-8038 from the version specification dated October 13, where the gas examples described are for proposed execution behavior. The state-gas reservoir will be fully passed with the call, and forwarding restrictions apply to execution gas, with gasleft() only reporting the execution balance. According to the reviewed rules, clearing storage slots that start at zero at the beginning of a transaction can replenish up to 97,920 execution gas; intermediary contracts may also credit back the accounted state-creation fees upon REVERT and return them to the caller.

According to CoinDesk, the patch for the XRP Ledger vulnerability was delayed until November as the number of validator supports dropped to 26 (out of a total of 35), resetting the countdown timer for its effectiveness.Currently, the number of supports has risen back to 31, but due to the need to recalculate the two-week countdown, this fix has missed the originally impending effectiveness window.

On October 21, Intel announced that construction workers have installed the first major structural truss at the new chip factory in New Albany, Ohio, marking the start of the next phase of construction. Naga Chandrasekaran, head of Intel's foundry, stated on the company's website that this is another step towards expanding advanced semiconductor manufacturing capacity in the United States.The factory was originally scheduled to begin chip production in 2025, but Intel has now postponed the completion target to 2030. The second Ohio wafer fab at the same site is planned to be completed by 2031, located northeast of Columbus. The delay is related to a recalibration of the foundry business under CEO Lip-Bu Tan. After taking over in 2025, Tan adopted a more cautious strategy, preferring to advance large-scale factory construction only after customer demand is clear. The project was initially driven by former CEO Pat Gelsinger, aimed at providing foundry services for external customers.As of the end of 2025, Intel has been mass-producing the most advanced 18A chips at its Arizona wafer fab, primarily for its own processors, and has not yet secured large external customers. Chandrasekaran also announced on the same day that operations for the next wafer fab in Arizona are expected to begin by the end of 2028, with construction and equipment installation currently underway. In September 2025, reports indicated that SK Hynix might be in talks with Intel to lease part of the foundry space at the Ohio plant for producing memory chips, but neither party has confirmed any plans.

Former Mt. Gox CEO Mark Karpelès questioned Ledger Support's previous statements. Ledger customer service had claimed that the secure element could detect physical tampering, and if additional hardware attempted to intercept signals, it would not pass authenticity verification. Karpelès pointed out that Ledger's own documentation states that if the original secure element is intact, authenticity verification cannot detect unauthorized physical modifications such as spy implants, which directly contradicts the customer service claims.Mark Karpelès stated that reports have shown that over $90 million has been stolen due to such "additional hardware" intercepting signals less than two months later, and that Ledger had published photos of spy implants for multiple models in a March 2026 academic article. Given the known threats, assuring users that authenticity verification can detect such modifications may constitute misleading advertising.

According to Bloomberg, citing informed sources, Nscale, an AI data center developer supported by Nvidia, initially sought an IPO valuation of about $30 billion, but some investors recently advocated for a valuation between $16 billion and $19 billion to attract buyers.Nscale is addressing comments from the U.S. SEC regarding its listing application documents and plans to initiate a roadshow after resolving these issues. Relevant discussions are still ongoing, and no final decision has been made. Previously, Microsoft withdrew from its collaboration with Nscale on a data center project in the UK due to project delays caused by limited power supply.

According to a report by the Korean News Agency, the South Korean government will convene representatives from the five major virtual asset exchanges—Upbit, Bithumb, Coinone, Digital X, and GOPAX—along with DAXA executives on October 20 to gather industry opinions regarding the virtual asset tax originally scheduled to be implemented in January 2027.The current proposal aims to impose a 22% income tax and local income tax on virtual asset transfers and lending income after deducting a basic tax exemption of 2.5 million Korean won. This tax policy has been postponed three times since it was proposed in 2020, and the government is still advancing preparations according to the original schedule. The National Tax Service of Korea is expected to release a related announcement in November.In addition, South Korea's financial regulatory authorities are accelerating the advancement of the government draft for the "Basic Law on Digital Assets," which is expected to be completed by the end of this month and initiate related consultation procedures.

The Solana Accelerate China team stated that due to an oversubscription of participants, in order to comply with local event regulations, the Hangzhou event originally scheduled for October 18 and the Shenzhen event originally scheduled for October 20 will both be postponed, with specific dates to be announced later.

Lily Liu, the chair of the Solana Foundation, stated in a post on October 16 that they showcased Solana on a large screen because of their deep affection for the Chinese community and gratitude for the warm welcome from the Chinese community. The display refers to the light show on the entire exterior wall of the Citibank building in Lujiazui, Shanghai on the evening of October 14.She mentioned that due to the publicity, the number of registrations for the Solana Shanghai event quadrupled overnight, far exceeding the limit reported to local government departments, and it could not prevent people from flooding the venue. To comply with local requirements, the event will be postponed and will be held when it can better accommodate the size of the community. She apologized to those who came from near and far wanting to participate in the Shanghai Solana event.

According to a report by The Block, Standard Chartered Bank has postponed its prediction for the stablecoin market to reach a scale of $2 trillion from 2028 to 2030. Geoffrey Kendrick, the bank's global head of digital asset research, stated that the $2 trillion scale estimate remains unchanged, but he believes the market will need an additional two years to reach it. Over the past 12 months, the supply of stablecoins has remained in the range of $300 billion to $320 billion, currently around $309 billion. Kendrick believes this slowdown is cyclical rather than structural, as it occurs during a period of weak activity in the cryptocurrency market.Kendrick pointed out that despite the stagnation in supply growth, the use and trading activity of stablecoins continue to rise. The on-chain original transfer amount set a monthly record of $19 trillion in May, with an average monthly scale of nearly $10 trillion this year, higher than the $4 trillion expected in 2025.The monthly average circulation velocity, which measures the number of times each dollar of stablecoin is transferred, has doubled this year to about 30 times, compared to 15 times in 2025, with USDT maintaining around 7 times, while USDC has increased from 45 times to about 80 times. Kendrick stated that the differences stem from different uses, with USDT primarily used for dollar savings in emerging markets, while USDC is more used for payments, financial transactions, and early payments between AI agents.Kendrick expects that competition in stablecoin payments and trading in developed markets will be the most intense, with potential challengers including Open USD, stablecoin infrastructure provider M^0, and the A+ network, which plans to allow banks to issue shared stablecoins and retain reserve earnings.

According to DealSite, storage chip manufacturer SK Hynix is expanding the mass production of the sixth-generation high bandwidth memory HBM4. However, some industry insiders believe that the expansion speed is slower than expected, and some equipment orders planned for this year may be postponed until next year.Industry insiders stated that some equipment originally scheduled for delivery in the second half of this year has shown signs of delay, and subsequent order plans have not yet been clarified. An anonymous source indicated that some equipment originally planned for this year may be pushed to next year, and there is no data confirming whether the delivered equipment is operating at full capacity. The investment plans related to HBM4 for next year have not been specifically communicated to some partners, and this year's orders have largely been completed, but there are no clear signals of increased or decreased investment. Reports suggest that the direct correlation between the equipment investment schedule and product quality issues has not yet been confirmed.Liu Henggen, a researcher at Daxin Securities, believes that concerns about major customers' HBM4 quality issues leading to performance below expectations are excessive. There may have been some issues in the backend process, but they cannot be regarded as insurmountable risks, and it is not yet time to discuss bad compensation. There are also industry claims that, against the backdrop of rising prices for general memory, some HBM investments may shift towards general memory. SK Hynix plans to prioritize the introduction of DRAM production equipment into the first cleanroom of the Yongin cluster Y1 wafer fab, and the industry expects that the initial production line will adopt the sixth-generation 10-nanometer 1c process, with the new capacity being prioritized for general DRAM. Some opinions also suggest that changes in the schedule of certain backend equipment are insufficient to determine that HBM4 mass production is hindered, as SK Hynix has already supplied HBM4 16-layer samples to major customers.

Bitcoin early contributor and cypherpunk Amir Taaki stated on X that he was deported after being questioned by Singapore police for 6 hours about "the work I am engaged in." The British-Iranian programmer claims that he has been in trouble with several countries since he went to Syria to fight alongside the Kurdish People's Protection Units years ago.Taaki mentioned that in the past year alone, he has been deported from Argentina and Mexico, and detained in Serbia and Japan. He stated that every time he encounters such situations, he asks for the reasons, but the authorities always claim it is just a random check, never providing specific reasons for his detention or questioning. "I am on a list, but I can't find any information about which country is sanctioning me."Taaki has long focused on Bitcoin privacy, being one of the first to implement CoinJoin and stealth addresses, creating libbitcoin, founding the UK's first Bitcoin exchange, and writing BIP 0001, which established the Bitcoin Improvement Proposal process. He is currently developing the crypto privacy protocol DarkFi.

According to CoinDesk, the U.S. Treasury Department announced sanctions against a member of Hamas's military wing, two French nationals, and two charitable organizations, accusing them of raising over $2 million for Hamas through cryptocurrency and so-called humanitarian donations in a fundraising campaign that lasted six years.The Treasury stated that Faouzi Barika and Amel Oualid raised funds in France under the guise of humanitarian efforts, subsequently transferring the money to Hamas. This network raised over $2 million between 2020 and 2026, with $1.5 million occurring after the Hamas attack on Israel on October 7, 2023. The two also sent hundreds of thousands of dollars in cryptocurrency to Saleem Abdallah Saleem al-Zaq in Gaza, who is the deputy battalion commander of Hamas's Kassam Brigades.The sanctions freeze the assets of the relevant entities within U.S. jurisdiction, and Americans are generally prohibited from engaging in transactions with them. Foreign financial institutions that knowingly facilitate significant transactions may face secondary sanctions risks, and restrictions also extend to companies in which the sanctioned parties hold more than 50% directly or indirectly. U.S. Treasury Secretary Scott Bessent stated that terrorist organizations like Hamas rely on complex financial intermediaries and fraudulent means. This move indicates U.S. concern about the role of cryptocurrency in broader fundraising networks, rather than viewing it as Hamas's primary source of funding.

According to a survey by the Financial Times, open-weight models are spreading from technology companies to traditional American enterprises. AlphaSense data shows that in August and September of this year, American companies mentioned open weights or open-source models approximately six times more than the same period last year during earnings calls and investor meetings. PNC Financial, logistics company CH Robinson, and Siemens have recently publicly discussed related applications.Tinder's annual AI spending has increased from about $1 million in January of this year to about $10 million in July, and it has begun to delegate some routine requests to open-weight models. AT&T stated that currently about 40% of AI tasks have been assigned to open models, with plans to increase this to about 70%. Its internal AI system processes approximately 45 billion tokens daily, using lower-cost models for simple tasks while continuing to use cutting-edge models like OpenAI and Anthropic for complex tasks.

The head of the Australian Senate Artificial Intelligence Inquiry Committee stated on Sunday that the CEOs of OpenAI and Anthropic have been summoned to attend the committee's hearing. This news was announced days after it was revealed that a rogue OpenAI robot had breached the database of Australia's healthcare system. Australian Prime Minister Albanese had previously strongly condemned the "Medicare" database leak incident.
