Trump signs quantum security executive order, which may promote post-quantum security research for Bitcoin

On Monday, U.S. President Trump signed two executive orders aimed at accelerating the development of U.S. quantum computing capabilities and advancing the government's transition to post-quantum cryptography. Although the executive orders did not directly mention Bitcoin, industry insiders believe this could benefit the blockchain's post-quantum security research and development.The two executive orders focus on defending against advanced cryptographic attacks and promoting cutting-edge quantum innovation. They include a clear timeline: to advance the construction of quantum sensors by September 2028 and require federal high-value assets and high-impact systems to complete the transition to post-quantum cryptography by the end of 2031. Project Eleven CEO Alex Pruden stated that this means the U.S. government will invest time and resources to achieve post-quantum security goals and may extend related requirements to the entire federal contractor system, not just limited to government agencies, thereby accelerating the implementation of post-quantum cryptographic technology.At the time of this policy announcement, the blockchain industry’s concern about quantum threats continues to rise. Organizations like the Ethereum Foundation and the Solana Foundation have begun advancing post-quantum security research and development, while the Bitcoin community is also discussing potential risks. Some publicly exposed Bitcoin addresses are believed to face the risk of private keys being derived once powerful quantum computers emerge in the future. Pruden pointed out that this executive order clearly sets the deadline for adopting post-quantum cryptography as 2031, which is more binding than the previous guidance from the U.S. government that proposed phasing out traditional cryptographic systems by 2035. For Bitcoin and the broader cryptocurrency industry, government investment in post-quantum security may accelerate the maturity of related tools, standards, and migration paths.

BIT's US stock financing trading is about to launch public testing, with professional trading capabilities continuously upgraded

BIT (formerly Matrixport) announced the official launch of its U.S. stock margin trading feature, which will be open for public testing starting June 26. BIT is the first platform in the cryptocurrency industry to offer margin trading functionality. Users can now submit margin loan applications through the official website or app. BIT will review applications based on account status and risk management requirements, gradually increasing the margin limits. Additionally, features such as securities lending are also in preparation and will be gradually opened based on regulatory requirements and product progress.During the public testing period, BIT will simultaneously launch the "First Margin Loan · Limited Time Interest-Free" and "Interest Cashback Gift" promotions: Users who use margin trading for the first time during the promotional period will enjoy 30 days of 0% interest on their first loan, allowing users to experience the efficiency of leveraged funds without interest. Elio Cui, head of brokerage services, stated: "BIT is the first to provide margin trading functionality, enhancing the customer journey from account opening, trading to fund leverage. This allows BIT customers to improve investment efficiency and strategically position themselves in the world's most wealth-generating assets without relying on bank cards or leaving the digital asset ecosystem."BIT also reminds users that while margin trading enhances the efficiency of fund usage, it also comes with corresponding risks. Users should fully understand margin rules and risk control mechanisms and participate cautiously based on their own risk tolerance.

OpenAI expands its cybersecurity program Daybreak, launching a dedicated defense model GPT-5.5-Cyber

OpenAI announced a comprehensive expansion of its cybersecurity program Daybreak, aimed at leveraging artificial intelligence to accelerate the discovery and automatic remediation of software vulnerabilities. The core of this expansion is the full version dedicated model GPT-5.5-Cyber launched for trusted defenders. It is reported that this model has set the highest score records in multiple cybersecurity benchmark tests, surpassing GPT-5.5's 81.8% and competitor Mythos 5's 83.8%, significantly improving the accuracy of vulnerability scanning and patch generation. At the same time, the synchronously updated Codex Security plugin has been deeply integrated into the developer workflow, supporting fully automated codebase scanning, threat modeling, and patch generation.In terms of ecosystem development, OpenAI has launched an exclusive partner program, allowing compliant security service providers to integrate GPT-5.5 with specific permissions into their commercial products; and has initiated the "Patch the Planet" program in collaboration with organizations like Trail of Bits to assist over 30 foundational open-source projects such as Python and Go in implementing vulnerability fixes. In addition, OpenAI revealed that it is currently engaged in deep cooperation with governments and institutions from multiple countries, including the United States, the United Kingdom, France, and Japan, to jointly enhance the cybersecurity capabilities of global critical infrastructure.
