OpenAI CEO Sam Altman published five operational principles under his personal signature and stated that in certain future periods, user access to model capabilities may be tightened for safety considerations, in order to strike a balance between empowerment and system resilience.Altman stated that key AI decisions should be driven by democratic processes and should not be determined solely by laboratories. He defended OpenAI's increased investment in computing power, the construction of data centers, and vertical integration strategies. He also mentioned potential challenges such as strong models possibly lowering the biological risk threshold, and reiterated OpenAI's continued iterative deployment strategy.

North Carolina Republican Senator Thom Tillis stated on Sunday local time that he would support the confirmation of Kevin Warsh's appointment as Federal Reserve Chairman, thereby clearing the last major obstacle for Trump's chosen successor to Powell.Tillis had refused to vote in support of Warsh for months, stating that he would not push for the confirmation of any Federal Reserve nominee as long as the Justice Department's criminal investigation into Powell was ongoing, calling the criminal investigation an attack on the independence of the central bank. However, that investigation appears to have concluded last Friday.

According to market news, SpaceX is expected to go public in June, potentially surpassing Saudi Aramco's $29 billion fundraising record to become the largest IPO in history. Meanwhile, OpenAI and Anthropic also plan to go public in the second half of this year, with the three companies expected to collectively attract over $240 billion in funding, likely marking a significant turning point for liquidity changes in the cryptocurrency market.Market analysis suggests that these super IPOs may significantly withdraw liquidity from risk assets, while the cryptocurrency market is in the same pool of funds. As mainstream cryptocurrencies like Bitcoin and Ethereum have been highly correlated with Nasdaq and U.S. stock market risk appetite in recent years, a large amount of capital shifting towards subscribing to tech giants' IPOs may weaken the buying support for BTC, ETH, and altcoins.

According to The Information, Anthropic and OpenAI have both experienced security incidents, raising market concerns about the safety of AI models themselves.Currently, Anthropic is investigating potential unauthorized access to its Claude Mythos model by users. Almost simultaneously, OpenAI was also reported to have accidentally exposed several unreleased models in its Codex application. Industry opinions indicate that these vulnerability incidents have intensified scrutiny on the security governance capabilities of AI companies and reflect that the security systems of current AI technology still need improvement as it rapidly develops. Analysts believe that even AI model providers that focus on cybersecurity capabilities face significant security challenges themselves. As AI is gradually used to defend against cyberattacks, issues related to platform security and access control have also become critical risk points.

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) announced sanctions against Cambodian Senator Kok An, accusing him of controlling "fraud parks" across the country, defrauding American victims through cryptocurrency investment scams.According to a statement released by OFAC on Thursday, in addition to Kok An, 28 other individuals and entities have been added to the sanctions list, all believed to be connected to his fraud network. This network is accused of luring victims into sending cryptocurrency assets under the guise of "high return investments." This action follows a raid by Cambodian police on two scam centers in the border city of Poipet. Previously, Kok An had been accused of operating scam bases in the area. OFAC stated that scammers typically gain victims' trust by establishing "friendships" or "romantic relationships," then guide them to participate in so-called cryptocurrency investment platforms, thereby defrauding them of funds, with the total amount involved reaching millions of dollars.It is noteworthy that some individuals involved in the scam activities are themselves victims of human trafficking, forced to engage in illegal activities under threats of violence. OFAC pointed out that these scam centers are often located in casinos or repurposed office parks, used not only for money laundering but also as bases for defrauding American citizens and committing human rights violations. Additionally, regulators have simultaneously shut down over 500 fraudulent website domains used for cryptocurrency investment scams, indicating that the U.S. crackdown on related criminal activities is intensifying.

AI Smart Routing and Infrastructure Network DGrid AI officially announces the launch of its AI inference API integrated with the x402 payment protocol. This API seamlessly merges payment logic with AI model invocation for the first time, allowing developers and AI Agents to complete authorization, inference, and payment within a single API request lifecycle without managing cumbersome API Keys or requiring centralized account pre-funding.It is reported that this API currently supports BNB Chain (BSC) as the underlying settlement network. With the micropayment features of the x402 protocol, the system can achieve extremely low-friction on-chain real-time settlement while ensuring that invocation costs remain absolutely controllable. Additionally, this API supports streaming responses and real-time usage feedback while being compatible with mainstream AI invocation methods, making it suitable for various application scenarios, including model selection for AI Agents, inference billing, intelligent agents, and multi-task execution.DGrid states that this initiative aims to completely break the prepaid barriers of traditional large model invocation and provide a programmable underlying payment infrastructure for building a fully automated AI Agent economy (machine-to-machine transactions).

According to The Block, Thom Tillis, a key negotiator for the U.S. Senate Banking Committee and a Republican senator from North Carolina, stated that the committee is unlikely to schedule a hearing to revise and vote on the cryptocurrency market structure bill within April.The main disagreement in the current legislation centers on how to handle rewards for stablecoins. The existing draft proposes to prohibit rewards for idle stablecoin accounts but allows earnings from trading activities; banking representatives are concerned that such earnings will attract deposits away from traditional banks, while cryptocurrency companies argue that limiting rewards will hinder innovation. Tillis suggested that the committee postpone the review until May.Previously, Senator Bernie Moreno warned that if the bill fails to pass before May, "digital asset legislation will not advance in the foreseeable future."

Aave officially stated that there may be two types of bad debts arising from the rsETH theft incident, depending on the different handling of rsETH. If the stolen losses are deducted from all circulating rsETH, it is expected to generate $123.7 million in bad debts, which is concentrated in the Ethereum mainnet in absolute terms, and is most severe in proportion on Mantle.If the value of the mainnet rsETH is guaranteed, and all losses are accounted for in the mapped version of rsETH on Layer 2, it is expected to generate $230.1 million in bad debts, all of which will be on Layer 2. Mantle will face a 71.45% WETH shortfall, and Arbitrum will face a 26.67% shortfall; the Ethereum mainnet will not be affected. Aave added that which situation ultimately occurs depends on decisions that Aave cannot control, mainly the accounting method for rsETH and the exchange rate update method of the LRT Oracle.

According to Decrypt, U.S. Senator Elizabeth Warren (a senior Democrat on the Senate Banking Committee) wrote to SEC Chairman Paul Atkins, stating that he may have "deliberately misled" Congress regarding the decline in the number of new enforcement actions by the SEC during a hearing, and pointed out that if there are significant false statements made to Congress, it could involve criminal liability.The report cites enforcement data disclosed by the SEC for 2025, stating that the SEC added a total of 456 new enforcement actions last year, of which about 200 were from the previous administration, and approximately 256 were added during the current administration, significantly lower than the average of about 765 per year over the past decade. Warren believes that the sharp decline in enforcement actions, staff reductions, and sudden leadership changes may weaken the SEC's ability to protect investors and maintain market order, and questions whether there is political favoritism and selective enforcement. The SEC declined to comment on this.
