According to the Wall Street Journal, the U.S. government's export controls and access restrictions on Anthropic's models Fable 5 / Mythos 5 partly stem from Amazon's cybersecurity research and AWS CEO Andy Jassy's communications with the White House.It is reported that the research submitted by Amazon indicated that through a series of prompt tests, researchers were able to induce Fable 5 to output sensitive information that could potentially be used for cyberattacks, raising security concerns. Subsequently, Andy Jassy reported the relevant findings to the U.S. government, prompting the White House to take further restrictive measures, including banning foreign users from accessing the model.At the same time, former U.S. Department of Commerce official Kate Koren revealed that the White House's existing policy stance on Anthropic may also have influenced this decision-making judgment, as there are differences between Anthropic and the White House on AI safety boundary issues, including the refusal to use the model for large-scale surveillance or lethal autonomous weapon systems. Although both sides had eased tensions and expanded cooperation earlier this year, this incident may once again exacerbate the strained relationship.

Marc Andreessen, co-founder of the venture capital firm a16z, published an article outlining his stance on AI regulation by the U.S. government. He stated that if so-called regulation means creating complex rules by people who do not understand the technology, suppressing innovation through layers of approval and compliance requirements, and ultimately becoming a tool for large enterprises to consolidate market positions and hinder newcomers, then he will firmly oppose such regulation.In his view, excessive regulation often leads to startups being crushed by cumbersome procedures and high compliance costs, causing innovative talent to flow to more open markets, while regulatory agencies themselves continue to expand, ultimately deviating from their original goals.Andreessen specifically criticized the regulatory mindset centered on the "precautionary principle," arguing that if this concept is amplified indefinitely, it could lead society to reject new technologies out of fear of potential risks. Many regulatory measures often arrive late, after fundamental changes in technology and industry have already occurred, making it difficult to address real issues and potentially becoming obstacles to innovative development. He also attributed the relatively lagging state of technological innovation in Europe in recent years to a culture of excessive regulation, believing that regulation should not become a moat to protect vested interests and raise market entry barriers.However, Andreessen emphasized that he does not oppose all forms of regulation. On the contrary, he supports rules that can build market trust, ensure public safety, and maintain fair competition. For example, preventing AI from faking voices to commit financial fraud, preventing deepfake content from interfering with elections, preventing technology from being used to harm vulnerable groups, and ensuring that consumers and businesses can safely use new technologies.In his view, reasonable regulation is like guardrails on a highway and a braking system in a car; it does not hinder technological progress but rather allows innovation to develop in a faster and more sustainable manner. Andreessen stated that what is truly worth pursuing is not "zero regulation" or "heavy regulation," but finding a balance between innovative vitality and social trust, which is also his unwavering stance.Previously, the U.S. government forcibly "recalled" commercial models due to jailbreak risks, leading Anthropic to take Fable 5 offline overnight and publicly protest.

According to The Wall Street Journal, Florida has launched a fierce attack in an increasingly intense protest against the so-called safety flaws of artificial intelligence chatbots, becoming the first state to sue OpenAI and its CEO Sam Altman.The lawsuit filed by Florida Attorney General James Uthmeier on Monday claims that OpenAI and Altman were aware of the safety risks associated with their products but ignored warnings that could harm users.

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.

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.

According to Bitcoin Magazine, Avihu Levy of StarkWare published a research proposal titled "Quantum-Safe Bitcoin Transactions Without Soft Forks," proposing a quantum-safe Bitcoin scheme called QSB.This scheme aims to enable Bitcoin transactions to resist quantum computing attacks without changing the core rules of Bitcoin. QSB replaces the elliptic curve security mechanism with hash-based assumptions, shifting security to hash preimage resistance to defend against the threat of Shor's algorithm. The scheme operates within the existing script limitations of Bitcoin and does not require consensus changes or soft forks.However, QSB transactions exceed the standard relay strategy limitations and cannot propagate through the network under default settings; they need to be submitted directly to miners through services like Slipstream. The paper estimates that the cost of generating valid transactions using cloud GPUs is approximately $75 to $150. The complete transaction assembly and broadcasting of the project have not yet been demonstrated on-chain.

According to Bloomberg, the Irish government officially launched the testing phase of the digital wallet on April 3 local time, which includes an age verification feature.According to a statement from the Irish Department of Public Expenditure and Reform, this digital ID will support age verification on social media platforms, aiming to protect children and adolescents from online harm.

Brazilian President Lula has signed Law No. 15,358, which explicitly incorporates seized cryptocurrency assets during law enforcement into the public safety funding system for expenditures such as police equipment, intelligence operations, and personnel training.The law allows for the temporary use of relevant cryptocurrency assets prior to final conviction with court approval. The new regulations also significantly expand the powers of judicial authorities, allowing them to freeze, block, or confiscate cryptocurrency assets during the investigation phase, including restricting access to exchange accounts, digital wallets, and related platforms. Once convicted, the individuals involved will be permanently deprived of the ability to use the formal financial system and cryptocurrency systems. Additionally, the law categorizes the use of encrypted communication tools or privacy technologies to conceal criminal activities as an aggravating circumstance, promotes cross-border asset recovery and intelligence sharing, and establishes a national database to integrate the financial structures of criminal organizations. Analysts believe that this initiative marks Brazil's shift of cryptocurrency assets from potential reserve tools to law enforcement resources, strengthening the crackdown on organized crime (such as PCC and Comando Vermelho) while advancing the judicial system's regulatory and disposal capabilities regarding digital assets.

According to the Securities Times, recently, the download and usage of the OpenClaw ("Little Lobster") application have been booming. In this regard, People's Finance learned from the Hong Kong Digital Policy Office, which is responsible for AI policy, that the office has been continuously monitoring the latest trends in artificial intelligence and has recently noted potential risks associated with OpenClaw, including excessive permissions, data leakage, and system security.It is recommended that relevant organizations and individual users take adequate security measures when deploying and using OpenClaw, specifically including: strengthening network controls, implementing strict isolation of the operating environment to reduce the risk of excessive permissions; enhancing credential management to avoid storing keys in plaintext in environment variables; strictly managing plugin sources to ensure the trustworthiness and security of plugins; continuously monitoring official patches and security updates, and promptly conducting version updates and installing security patches.It is reported that the Hong Kong government places great importance on the governance and risk prevention of artificial intelligence applications, having developed documents such as the "Ethical Framework for Artificial Intelligence" and "Guidelines for Generative Artificial Intelligence Technology and Applications in Hong Kong." Additionally, the government has established a comprehensive "Government Information Technology Security Policy and Guidelines" for all departments to follow and use. Each department must conduct a risk assessment before installing various types of software.

The founder and CEO of Gate, Dr. Han, expressed his views on the market positioning of gold and Bitcoin on platform X. Dr. Han pointed out that against the backdrop of rising global political and economic uncertainties, gold prices have reached new historical highs, and market volatility has significantly increased, with funds seeking certainty again.Dr. Han believes that although the market has long compared Bitcoin to gold, the two are fundamentally different. The reason gold continues to be allocated during turbulent periods is due to its repeatedly validated "safe lower bound" attribute over thousands of years; whereas Bitcoin has never been defined as a safe-haven asset, and its value logic is more reflected in betting on future growth potential.As the participation of traditional financial assets in the crypto market continues to rise, Gate has also accelerated its layout in the TradFi direction, gradually expanding trading categories such as precious metals, foreign exchange, indices, and stocks. According to CoinGlass data, the 24-hour trading volume of Gate XAUT (gold) contracts has exceeded $483 million, ranking third globally.

Binance officially released the 2025 User Security and Protection Report, stating that since 2023, direct economic losses caused by major illegal activities have decreased by 96%; it has prevented potential losses of $6.69 billion for 5.4 million users; handled over 71,000 law enforcement requests, assisted in the seizure of $131 million in involved funds, and provided over 160 training sessions for law enforcement agencies.

On-chain analyst Willy Woo tweeted that the future "quantum computing era" may allow public keys to be reverse-engineered into private keys, leading to asset risks. Currently, Taproot addresses starting with "bc1p" are not quantum-safe, while SegWit addresses starting with "bc1q" still have protective capabilities. He advises users to transfer BTC to SegWit or legacy format addresses and to avoid spending until an upgrade to quantum-safe protocols is completed to prevent exposure of public keys.Woo expects that the Bitcoin network will complete its quantum-safe upgrade in about 7 years, while quantum threats may emerge as early as after 2030.

The Berachain Foundation announced early this morning that approximately $12.8 million in stolen funds from the BEX / Balancer V2 vulnerability has been fully recovered and returned to the foundation's deployment wallet.The team expressed gratitude to the white hat hackers who assisted in recovering the funds and plans to lift the malicious tags on their addresses, considering issuing a bounty as a token of appreciation. Currently, all functions of BEX (including exchanges, withdrawals, deposits, etc.) remain restricted, while the minting and redemption of HONEY have been restored. Due to the suspension of BGT and incentives in the past 24 hours, the on-chain APR may show anomalies. Regarding the allocation of the affected funds, the Berachain core team is developing a system to attribute and distribute them to the original user addresses one by one. Deposits of BEX that were not affected by the vulnerability are currently also unable to be withdrawn; the team stated that this is a precautionary measure and is closely monitoring the progress of Balancer's subsequent investigation to ensure that all user funds can be safely returned as soon as possible.
