U.S. Treasury Secretary Becerra stated that the recent rise in U.S. Treasury yields is consistent with global trends and does not warrant excessive panic. He praised the U.S. financial intervention in Argentina and expressed an open attitude towards similar assistance in the future.

YouTuber PewDiePie stated in his latest video that his account was banned twice by OpenAI while training the small local AI model Ajax. He mentioned that he originally hoped to distill reasoning tokens from OpenAI's flagship model GPT-5.6 Sol, released on July 9, and find a study that utilized OpenAI's own API to crack encrypted reasoning content. He claimed that he did not actually crack OpenAI but was still banned, and after appealing, his account was restored after some time.After the account was restored, he used Sol again to generate seed data and was subsequently banned for the second time. OpenAI's terms of service prohibit the development of competing models using its outputs. Ajax is a 9 billion parameter model built on Alibaba's open-source model Qwen 3.5, which will run in PewDiePie's free self-hosted AI application Odysseus launched in June, and it is not yet available for download.To prevent Ajax from being censored, he used the open-source tool Heretic to remove the model's built-in refusal mechanism, a technique known as abliteration. He stated that Ajax suffered a bit of brain damage as a result, but it has about a 90% success rate in tasks like organizing the inbox and browsing the web, and he continues to train it using the GRPO method. He mentioned that when choosing which refusal behaviors to remove, he draws the line at harming others or harming himself.

ARK Invest CEO Cathie Wood stated at a summit hosted by Robinhood in Houston that investors have traditionally "followed developers" to gauge technological trends, but now they may need to "follow agents." The AI agents she refers to are software that can perform tasks on behalf of humans, rather than just answering questions or generating text. This statement came towards the end of a discussion on AI, private markets, and technology investments.As AI agents shift from answering questions to executing operations and spending funds, the type of financial infrastructure they will use has become a focal point. SharpLink co-CEO and former BlackRock digital asset head Joseph Chalom believes that the financial system used by AI agents should not be controlled by a few banks or tech companies. He cited the example of authorized agents booking hotels, pointing out that users should be able to set spending limits, revoke authorizations at any time, and view the agents' transaction records. Additionally, users should be able to transfer the agents' identities, financial information, and permissions between different financial service providers, similar to mobile number portability.Chalom believes that open blockchains like Ethereum can provide a universal financial network for different agents, applications, and companies to use collectively, eliminating the need for each AI company to build its own closed payment system. A report from BlackRock in September also noted that AI agents could create new demands for machine-oriented payment systems, such as payment API calls, purchasing data, or renting computing power, with stablecoins and blockchain being one of the viable solutions. Coinbase's x402 is designed to enable machines to pay for online services like data or APIs.

On-chain liquidity protocol Arrakis Finance released a study tracking the on-chain buying records of 10 tokenized dollar yield products, using Ethena's sUSDe as a benchmark. The study covered 71,697 buyers with a total buying amount of 91.3 billion dollars. Of the 12.4 billion dollars in categorized demand, about two-thirds came from protocols and DAO treasuries, while the remainder came from individuals, exchanges, market makers, and crypto funds, with no purchases clearly traceable to traditional financial institutions such as pensions, asset management firms, or banks.Wallets with single purchases of 1 million dollars or more accounted for about 4% of buyers but held approximately 93% of the funds; among them, 2,586 buyers contributed over 90% of the nominal purchase amount. The median purchase amount for institutional buyers of Centrifuge's JAAA was about 29.1 million dollars, nearly three times that of the next product. About 80%, totaling 17.4 billion dollars, was settled in USDC, while USDT accounted for about 4.4 billion dollars, almost all of which was used for syrupUSDT. Primary subscriptions were the main pathway, with secondary market purchases accounting for less than 6%, and only sUSDe had 55% obtained through decentralized exchanges.The median first activity time for buyer wallets concentrated around mid-2024, described as new entrants of crypto-native funds. By time zone, Europe, the Middle East, and Africa accounted for 42%, Asia-Pacific for 40%, and the Americas for 18%. After tracing back two hops for 5.17 billion dollars of unmarked institutional-level funds, exchange sources accounted for 40% (Binance 1.12 billion dollars, Coinbase 970 million dollars), DeFi native funds accounted for 38%, and another 22% could not be identified.

David Robinson, an executive from OpenAI's safety systems team, left last week. Robinson was previously responsible for OpenAI's policy planning and played a significant role in enhancing model transparency, including the development of system cards.This departure marks another personnel change in OpenAI's safety department, as safety lead Johannes Heidecke also left earlier this year. The company announced on Thursday that it parted ways with three researchers for violating sensitive information sharing policies.Amid the backdrop of security vulnerabilities at Hugging Face and a series of abnormal behaviors in AI models, CEO Sam Altman stated at the developer conference on Tuesday that safety and alignment work must stay ahead of the development of model capabilities. Before his departure, Robinson publicly expressed concerns, believing that while OpenAI is undergoing significant changes, there remains uncertainty about whether the pace of transformation is sufficient to address the challenges posed by high-performance AI models.

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.

European Central Bank Executive Board member Isabel Schnabel stated that central bank money must be on-chain; otherwise, the tokenized market will increasingly rely on private or foreign currency settlement assets.CoinDesk cited her viewpoint, stating that in the absence of on-chain central bank money, the settlement of the tokenized market will shift more towards privately issued assets or foreign currency-denominated assets. Schnabel believes that bringing central bank money on-chain helps maintain the settlement anchor role of public money in a tokenized environment.

On October 2, Canadian Prime Minister Mark Carney announced the establishment of the Prime Minister's National Artificial Intelligence Advisory Council in Ottawa, which will provide independent and pragmatic advice on Canada's artificial intelligence transformation. The council will bring together stakeholders from the public and private sectors to provide input on the evolution of the AI for All national strategy, covering areas such as accelerating adoption, nurturing national leading enterprises, building sovereign artificial intelligence infrastructure, enhancing AI safety, protecting democracy, and ensuring that all Canadians benefit.Council members include Ajay Agrawal, Yoshua Bengio, Sanja Fidler, John Graham, Gillian Hadfield, Jordan Jacobs, Eric Lamarre, Valérie Pisano, Senator Thomas Pitfield, Jody Thomas, Louis Vachon, Michelle Zatlyn, and of course, Patrick Pichette as a member. The council is supported by a small team from the Privy Council Office, while policy decisions and implementation remain the responsibility of the relevant ministers and departments.Carney stated that the prosperity and sovereignty of the artificial intelligence era belong to countries that can build, adopt, and govern artificial intelligence according to their own conditions, and the council will provide recommendations on how to manage risks, seize opportunities, and improve the lives of all Canadians.

The cryptocurrency exchange platform Coinbase has obtained a Financial Services License (FSP) issued by the Financial Services Regulatory Authority (FSRA) of the Abu Dhabi Global Market (ADGM). This license allows it to arrange investment transactions and provide custody for tokenized securities. Coinbase describes this license as the regulatory foundation for its international tokenization hub and the first of its two major non-U.S. institutional businesses established in the UAE, the other being its derivatives business in Dubai.According to the scope of the license, the FSP covers the arrangement and custody of tokenized stocks fully backed by underlying shares. Holders of digital securities can gain economic exposure such as dividends, while voting rights and redemption rights are subject to the conditions outlined in each prospectus. Coinbase states that investors only need a crypto wallet to trade, and secondary transfers do not require a brokerage account or banking relationship, but redeeming profits for fiat currency still requires a bank or brokerage account.Brett Tejpaul, Co-President of Coinbase Institutional: Currently, there is no major financial center that has established a framework that simultaneously regards tokenized stocks as securities, blockchain-native tokens, and composable DeFi assets. Arvind Ramamurthy, Chief Market Development Officer of ADGM, stated that the Coinbase hub reflects the center's progressive, robust, and internationally aligned regulatory framework. The FSRA issued its first virtual asset rules in 2018, which include protective measures such as sanctions screening and the ability to freeze or seize assets at the wallet level. ADGM applies English common law, and the FSRA's authority differs from that of the UAE Securities and Commodities Authority; registered entities do not automatically obtain a passport in other Gulf Cooperation Council jurisdictions.
