Bitcoin Red Team member @Rob1Ham stated that OpenAI has prevented him from continuing security analysis on the Bitcoin codebase, despite his responsible disclosure of real vulnerabilities present in it.Rob1Ham mentioned that he had previously completed the authentication and onboarding process related to OpenAI's cybersecurity capabilities, but is currently unable to continue investigating whether the remediation measures are sufficient or if other vulnerabilities still exist. He stated that he will resume Bitcoin security research using Chinese open-source AI models in the future. Rob1Ham said, "Black hat hackers will not attack these issues, white hat hackers will." He also stated, "For those who do not comply with the rules and engage in harmful behavior, intelligence is unrestricted, while those committed to reducing harm are excluded."

The Shanghai headquarters of the People's Bank of China held a work meeting for the second half of 2026, during which it emphasized the need to firmly uphold the bottom line of preventing systemic financial risks. It will continue to strengthen the assessment and verification of bank institution ratings. Monitoring and analysis of systemically important financial institutions will be enhanced.There will be ongoing prevention and handling of risks related to speculative virtual currency trading. Efforts will be made to actively promote the standardization of financial product online marketing behaviors by local institutions. The mechanism for preventing and resolving systemic risks will be continuously improved. There will be a strengthened crackdown on illegal financial activities. The framework for macro-prudential management will be continuously refined. The level of cross-border financial risk monitoring will be comprehensively enhanced.

Circle's Senior Director of Strategy and Policy, Patrick Hansen, stated that after the comprehensive implementation of the EU's Markets in Crypto-Assets Regulation (MiCA), licenses have been issued for 35 electronic currency tokens from 21 issuers, and local issuers are making good progress. Patrick Hansen pointed out that the strict regulations of MiCA have made it impossible for most major stablecoin issuers, including Tether, to meet operational requirements. Currently, only USDG, USDC, and EURC comply with the framework requirements, while other stablecoins fall outside the regulatory scope of MiCA, leaving EU users unprotected or unable to access services.He believes that the upcoming review of MiCA should address this issue and provide a more pragmatic operational pathway for foreign issuers. The EU's Directorate-General for Financial Stability, Financial Services, and Capital Markets Union launched a public consultation on May 20 to assess whether the current framework is still applicable, with the consultation continuing until September 30.

According to official news, the Ethereum Foundation's "Trillion Dollar Security" (1TS) has announced a special grant to the Freedom of the Press Foundation (FPF) to support the ongoing development of the open-source tool WEBCAT, aimed at addressing the long-standing front-end code verification security gap in Ethereum wallets and decentralized applications (DApps).WEBCAT (Web-based Code Assurance and Transparency) is an open-source tool designed to help browsers verify whether the code loaded by a website matches the version publicly released by the developer.This funding will promote the expansion of WEBCAT to Ethereum wallets and application scenarios, enabling users to verify whether the front-end pages they access have been tampered with.The Ethereum Foundation stated that while HTTPS can verify the website a user is connected to and encrypt communication, it cannot prove that the front-end code actually running on the website is the same version released by the developer. If an attacker controls the website's front-end code, they may modify the transaction receiving address without the user's knowledge or induce the user to sign transactions that do not match the content displayed on the page.The Ethereum Foundation noted that front-end attacks have become a significant security risk for blockchain infrastructure, with malicious modifications to web interfaces potentially leading to supply chain attacks, DNS hijacking subsequent attacks, and user interface deception.WEBCAT was initially developed by the Freedom of the Press Foundation to enhance the code credibility of secure communication systems like SecureDrop.With this expansion into the Ethereum ecosystem, it will complement security measures such as "Clear Signing" in the 1TS program: the former helps wallets confirm that the application front-end has not been tampered with, while the latter helps users understand the transaction content they are approving.

The Ethereum community has submitted a new improvement proposal EIP "Tapered Issuance Burn," aimed at adjusting the ETH issuance mechanism to reduce the centralization and dilution risks brought about by excessively high staking ratios. The proposal points out that the ETH staking ratio exceeded one-third of the total supply in April 2026 and continues to grow.Under the current issuance curve, even if all ETH participates in staking, the staking yield will not be lower than approximately 1.5%, leading to a lack of a "closure mechanism" for staking incentives. This EIP proposes to destroy a portion of the theoretical rewards for validators in each epoch, with the destruction ratio increasing as the staking scale grows: when the staking rate reaches about 50%, the net staking yield will gradually drop to zero. The proposal believes that this mechanism can limit the continuous expansion of ETH supply, reduce the dilution pressure on holders, prevent excessive concentration of staking in custodial institutions and staking service providers, and maintain ETH's attributes as a neutral asset and a store of value.According to the design, under the tapered issuance mechanism, the ETH issuance will peak when the staking rate is around 20%, with an annual issuance rate of about 0.5%, and will drop to zero when the staking rate reaches 50%. Combined with the EIP-1559 and Blob fee destruction mechanisms, ETH supply may more frequently enter a deflationary state in the future. The authors of the proposal state that this plan is not aimed at individual stakers but rather corrects the long-term dilution issues brought about by the current issuance curve, allowing staking yields to ultimately be determined by market risk premiums rather than fixed algorithmic incentives.

Web3 security company CertiK released the "2026 First Half Wrench Attack Report." The report shows that in the first half of 2026, a total of 52 publicly verified wrench attack incidents were recorded globally, an increase of 33.3% year-on-year; related losses amounted to approximately $124 million, an increase of about 11.8 times compared to the same period last year.The report points out that attackers are shifting from exploiting technical vulnerabilities to targeting asset holders and their real-world relationship networks, with home invasion incidents rising from 1 in the first half of 2025 to 20, accounting for 41% of the total incidents during the same period. Europe has become a high-frequency attack region, with 33 incidents occurring in France, accounting for 63.5% of global cases.CertiK states that as real-world risks become a significant challenge for digital asset security, businesses and high-value individuals need to establish a more comprehensive protection system. CertiK has launched operational security services to help identify risks related to the exposure of information such as identity, home, residence, and travel trajectory; at the same time, through CertiK Security Workspace, it correlates off-chain intelligence, on-chain transactions, and AML risk signals to support institutions in tracking and analyzing cybercrime activities.In addition, CertiK is strengthening cooperation with international law enforcement agencies such as Interpol and Europol to provide technical support for cross-border attack investigations and security policy research.

The Financial Services Commission of South Korea responded positively to the recent controversies surrounding single-stock leveraged exchange-traded funds (ETFs) when it released supplementary regulatory measures. Byeon Je-ho, the Director of the Capital Markets Bureau of the Financial Services Commission, clearly stated that launching leveraged ETF products targeting single stocks such as Samsung Electronics and SK Hynix in the domestic market has indeed had a significant effect in locking in domestic investment demand and preventing capital outflow to overseas leveraged markets like Hong Kong or the United States.In response to external accusations that single-stock leveraged ETFs are the "main culprit" behind the recent increase in volatility in the South Korean stock market, the Financial Services Commission refuted this claim. Byeon Je-ho pointed out that the recent dramatic market fluctuations cannot be solely explained by leveraged ETFs, with the core reason being the alternating expectations of the global semiconductor industry cycle. Data shows that from May 26 to July 10, the annualized daily return volatility of U.S. SanDisk (131%), Micron (123%), and Japan's Kioxia (118%) was higher than that of South Korea's SK Hynix (113%) and Samsung Electronics (96%). Additionally, some investors' contrarian operations have played a role in stabilizing stock prices to some extent.Regarding the demands from some politicians and market participants to "forcefully delist single-stock leveraged ETFs," the Financial Services Commission clearly rejected this request. The official explanation stated that delisting must meet statutory termination criteria such as a sharp decline in market value or a lack of liquidity providers (LPs), and currently, the market is showing signs of heating up due to excessive demand, which does not meet the delisting conditions. The Financial Services Commission indicated that such calls should be understood as the market's urgent expectation for strengthened compliance and robust regulatory measures.

According to Jinshi reports, the White House stated that President Trump will not allow Iran to launch attacks in the Strait of Hormuz without facing consequences. The United States can strike Iran at any time and in any place.

According to Etoday, the Financial Services Commission of South Korea has announced a draft amendment to the "Special Law on Preventing Telecom Financial Fraud and Returning Victim Funds," planning to include funds from phone scams that are transferred to crypto assets within the scope of victim compensation, and to clarify the standards for the return and valuation of crypto assets. The relevant regulations are expected to officially take effect on October 1.According to the new regulations, if the frozen assets are cryptocurrencies, victims will generally be compensated based on the type and quantity of assets; if the defrauded assets differ in form from the frozen assets, compensation will be made in the form of assets that existed at the time the account was frozen. In cases where cash and crypto assets are mixed, the regulatory authorities will value the crypto assets based on the market price at the time of freezing to determine the final compensation amount.The Financial Services Commission of South Korea stated that clarifying the form of returned assets and the timing of valuation will help achieve faster and fairer compensation in complex cases involving mixed funds from multiple victims. It is reported that the public consultation for the draft amendment will continue until August 24.

According to the report from the Cybersecurity Threat and Vulnerability Information Sharing Platform (NVDB) of the Ministry of Industry and Information Technology on July 8, recent monitoring has found serious security backdoor risks in the AI programming tool Claude Code developed by the American company Anthropic.The report pointed out that the affected versions of Claude Code are from 2.1.91 to 2.1.196. This tool has a built-in monitoring mechanism that can, without user consent, secretly transmit sensitive data such as users' location and identity identifiers to remote servers. The official recommendation is for relevant units and users to immediately conduct a comprehensive inspection, uninstall the affected versions of the terminal, or upgrade to the latest secure version that has removed the related backdoor code; at the same time, they should strengthen the control of external access permissions and traffic monitoring for development tools within the core business network segment to prevent the illegal transmission of sensitive data.
