TrendForce reported on October 12, citing Chosun Biz, that as AI packaging accommodates more computing and storage chips, the intermediary layer connecting computing chips and HBM is expected to significantly increase in size, making next-generation HBM cooling more important. Samsung Electronics is preparing multiple technologies to address the cooling challenges of HBM4E, which is scheduled to begin mass production next year.Currently, the area of the AI intermediary layer is about 5.5 times the maximum exposure area of 858 square millimeters of an EUV lithography machine. Semiconductor equipment industry insiders expect that the intermediary layer carrying HBM could expand to 9 times, 12 times that area, and ultimately about 40 times. Reasons include limitations in process miniaturization and the popularity of chiplet-style 2.5D packaging, where multiple computing chiplets and HBM stacks are placed on the same intermediary layer, making it difficult for a single advanced process chip to meet AI computing power demands.Samsung is considering hybrid copper bonding and thermal path blocks. The former replaces the micro bumps between stacked DRAM chips with direct copper-to-copper connections, which can reduce inter-layer gaps, make the stack thinner, and improve heat dissipation, a technology Samsung showcased at NVIDIA GTC in March 2026. The thermal path block establishes a dedicated thermal path in the D2D PHY area responsible for high-speed transmission between HBM base chips and GPUs, which Samsung is validating with HBM4E and plans to implement in HBM5. According to ETNews, SK Hynix's iHBM places high thermal conductivity but electrically insulating cooling materials around the heat-concentrated D2D PHY, which is expected to reduce thermal resistance by about 30%.

Papertrade's official response to the allegations of price manipulation and the existence of obvious loopholes in the protocol states: It has never been possible for small orders to have the same priority as large orders. If this were done, the front end would suffer from congestion due to junk trading, and the consequences would be much worse than the existing queuing mechanism.Under these constraints, we have designed the fair launch to be as inclusive as possible.Last night, the attempts to manipulate BTC/ETH on Hyperliquid BBO were not due to flaws in the mechanism that took six months to design. These situations had already been considered; it was only because the position limits were set very loosely in the early stages to cope with congestion that such occurrences were possible. If position limits were set during peak demand for launching, it would only exacerbate the slow experience, and the queuing mechanism itself, due to the uncertainty of opening/closing confirmation times, naturally provides protection against manipulation.As congestion eases, we have begun to tighten position limits on-chain and at the relay level. In such a system, manipulation attacks are always possible— the key is whether the attempt is economically viable. The official goal is to set parameters to a point where it is almost never profitable; even if successful, the tail risk is extremely high, and the expected value is negative.

The head of research at OpenAI issued a statement in response to an open letter from three former employees, Jasmine, Mikita, and Tomek. The company stated that after a thorough investigation, the three violated clear policies regarding the handling of sensitive information; serious breaches of trust discovered during the internal investigation exceeded the scope disclosed in the open letter, leading to the termination of their employment last week, a decision that will be upheld.OpenAI emphasized that this decision is not aimed at those who raise safety concerns or express opinions publicly. The company stated that there are intense and critical safety and research discussions internally every day, and it encourages questioning; it maintains a tolerance for good-faith mistakes and will not fire employees for raising concerns.Regarding the safety issues mentioned in the open letter, OpenAI stated that it is finalizing contracts with third-party security assessment organizations, with details expected to be announced in the coming weeks, and it is committed to including external evaluators in its safety work. The company recognizes that maintaining the monitorability of cutting-edge models requires collective investment from the entire industry, stating that this area has long been a focus of its research and will continue to receive significant resources.

On October 9, Binance founder CZ posted on X, responding to Ethereum co-founder Vitalik Buterin's lengthy article about the potential impact of artificial intelligence accelerating mathematical research on cryptographic security. CZ rated Vitalik's mathematical level at 99.99 points, while he rated himself at 0.01 points, joking that together they might achieve something; he also mentioned that people might not fully understand Vitalik's articles like himself, but even so, such analytical discussions are worth reading.Previously, Vitalik warned in a post that the acceleration of mathematical research by artificial intelligence could significantly weaken the practical security of lattice-based cryptography in the next two years, involving technologies such as ML-DSA and fully homomorphic encryption, and could even expose ECDSA to cracking risks sooner than expected. He believes that artificial intelligence could drive mathematical research progress equivalent to the past 50 years within two years, which is why the Ethereum Lean roadmap has gradually shifted towards pure hash signature schemes over the past year, reducing reliance on lattice cryptography.

South Korean Deputy Prime Minister and Minister of Strategy and Finance Lee Hyeong-ryeol stated that in response to the virtual asset taxation policy planned for implementation in 2027, various opinions proposed by the National Assembly, as well as those from experts, industry professionals, and relevant stakeholders, will be widely collected. South Korean lawmaker Kim Sang-hoon questioned that several months before the implementation of the virtual asset taxation, the relevant infrastructure is still not fully developed, including insufficient tracking and verification capabilities for trading records on overseas exchanges, DEX, DeFi, and other platforms.Regarding the expected tax revenue scale from virtual asset taxation, Lee Hyeong-ryeol stated that there are indeed parts that are "difficult to accurately grasp." Since taxation requires obtaining taxpayer declaration data first, further tax estimation can only be conducted after the relevant declaration system is launched next year, and a careful evaluation of the related policies will be carried out.

A community user posted that after connecting to the free Wi-Fi at Singapore Airport, a "small wallet" that had not been traded for a long time had 3.7 BNB transferred away, and reminded users not to casually connect to public Wi-Fi. The user stated that the wallet had no transaction records for the previous few months, but the assets were transferred after connecting to the airport's free network.In response, Binance founder Changpeng Zhao stated, "I have always advised everyone not to connect to Wi-Fi, especially public Wi-Fi. But just connecting to Wi-Fi shouldn't lead to a wallet being stolen, was there some other operation in between?"

On October 8, the spokesperson of the Ministry of Foreign Affairs, Mao Ning, hosted a regular press conference. A Reuters reporter asked about the allegations made by the American cybersecurity company CrowdStrike that Chinese individuals and related institutions used AI tools to attack South Korean financial institutions.Mao Ning stated: "I am not familiar with the specific situation mentioned. As a principle, China has always opposed and legally cracked down on hacking activities, and even more so opposes the dissemination of false information for political purposes." She also stated that artificial intelligence profoundly affects cybersecurity, and the international community should strengthen cooperation and dialogue, formulate new international rules, and jointly maintain cybersecurity.

The co-founder of the Bitcoin financial asset protocol Solv Protocol, Meng Yan, stated that he has withdrawn from the daily operations of Solv and did not participate in the BTC+ business, and was unaware of the situation at the time. A user claiming to be the party involved later contacted him, asking him to communicate with the business team. Meng Yan mentioned that Solv had announced a BTC+ security incident in July, where the deposit of 50 BTC and subsequent operations constituted important conditions exploited by the attack path; the attack occurred just three days after the related operations, and Solv promptly identified and prevented it, protecting BTC+ user funds.Meng Yan stated that the above situation alone cannot prove a direct correlation between the two matters, but it is sufficient to trigger a higher-level security review. Therefore, risk control protected the funds in question and required the user to explain the situation. He noted that during the review, Solv never required the user to undergo any form of KYC, nor did it require ordinary BTC+ users to use real names; the review focused on whether the identity and account explanations submitted by the user were consistent, whether the related accounts were controlled by the user, and whether the explanations for key operations could correspond with objective records. Risk control feedback indicated that the user had used multiple different names and online identities, and several key factual statements were inconsistent.Meng Yan provided an example, stating that the user explained that on July 18, they saw a similar transaction by someone else, but the verification showed that the transaction occurred on July 20; the user later claimed they acted after seeing related content on the Solv official website, but the page at that time did not contain the content they referred to. He stated that risk control cannot lift security restrictions before eliminating doubts and has never refused to resolve issues through formal channels such as judicial procedures. In the section marked as personal thoughts, he mentioned that to his knowledge, the asset remains intact, can be traced on-chain, and has not been transferred, mortgaged, or disposed of.

On October 7, at a meeting of the Hong Kong Legislative Council, legislator Chan Chun-ying raised a written inquiry regarding the regulation of emerging payment platforms. The Acting Secretary for Financial Services and the Treasury, Chan Ho-lam, provided a written response. The inquiry pointed out that in recent years, new aggregation payment platforms have emerged, reaching out to small merchants with low fees and "buy now, pay later" methods. Some platforms have reported overdue payments and false entries, and there are platforms that are registered only as financial technology companies, without obtaining financial licenses, and have not disclosed their partner organizations or operational status.Chan Ho-lam stated that the government and financial regulatory agencies continue to monitor emerging payment models and take enforcement actions within the statutory framework. After consulting the Monetary Authority and Customs, from January 2024 to September 2026, the Monetary Authority received 16 complaints regarding the suspected unlicensed issuance or operation of stored value payment tools. After investigation, one was substantiated, and the complainant did not report any financial loss. The Monetary Authority is following up with the relevant companies.The response pointed out that the Monetary Authority regulates stored value payment tools under the Payment Systems and Stored Value Facilities Ordinance. Unless legally exempt, issuing or operating without a license in Hong Kong is illegal. Money services that operate currency exchange and cross-border remittances must apply for a license from Customs unless exempted. Non-bank institutions providing "buy now, pay later" services involving loan activities must apply for a money lender license under the Money Lenders Ordinance. Cases suspected of being unlicensed or non-compliant are handled by the Monetary Authority, which may collaborate with other regulatory agencies or refer to law enforcement departments.

According to the Arbitrum Security Committee report, in response to the increasingly complex risks of AI-assisted attacks, Arbitrum took emergency action around 23:30 Beijing time on October 2 to temporarily halt the activation of new Stylus contracts on the Arbitrum One and Nova networks.This restriction mainly targets programs and application updates that require new activation, while already activated Stylus applications can continue to operate, and the deployment and execution of regular Solidity contracts are not affected. Arbitrum officials stated that this preventive measure stems from threats of WebAssembly program attacks targeting non-standard Stylus compiler toolchains, and no risk of fund theft has been discovered so far. The main concerns are on-chain activity and denial-of-service (DoS) attacks. Developers can still extend the lifecycle of existing programs through a permissionless keep-alive renewal mechanism, but they cannot activate expired programs or new version applications.
