On July 17, French Foreign Minister Jean-Noël Barrot submitted Bill No. 921 to the Senate, proposing to incorporate the Crypto Asset Reporting Framework (CARF) established by the Organisation for Economic Co-operation and Development (OECD) into French law and to automatically exchange encrypted data with 48 countries that have signed related agreements.The exchanged information includes specific transactions, user names, addresses, tax identification numbers, places of residence, and the cumulative transaction value during the reporting period. EU member states have prepared to conduct relevant data exchanges based on the DAC-8 directive, which will take effect on September 30, 2027. After the bill is approved, the French government will accelerate the collection of encrypted data. A Chainalysis report indicates that by 2026, France had recorded 30 publicly known violent robberies of crypto assets; the report states that a tax official in the Paris region is suspected of selling data on high-net-worth crypto holders.

The cryptocurrency hardware wallet manufacturer Coldcard has released an update on its customer data retention policy. Due to legal compliance requirements arising from the security incident disclosed on July 30, the company has temporarily suspended its original automatic customer data deletion mechanism.Previously, Coldcard's standard practice was to automatically clear customer records after 120 days, retaining only the user's email address and country information, while allowing customers to request early deletion of data at any time after product delivery. Coldcard stated that due to the security incident involving ongoing and potential legal proceedings, the company is obligated to retain records that may be relevant to litigation. Therefore, customer data that was originally scheduled for deletion will be temporarily retained until the law permits the resumption of normal processes.However, users can still request Coldcard to handle their personal information according to the original data retention policy. If users wish for their data not to be included in this legal retention scope, they can contact official customer service to make a request. Coldcard emphasizes that the retained data will be strictly protected, accessible only to authorized personnel, and will not be used for any purposes other than fulfilling legal obligations. The company will restore the previous automatic data deletion mechanism once legally permissible.

The Volcano Engine officially launched the Seedance 2.5 API. Compared to Seedance 2, the new version has significantly improved in areas such as instruction adherence, long narratives, character consistency, realism, lighting and shadow quality, and sound effects. It natively supports 30-second video output, a maximum of 50 multimodal material references, and is compatible with more than a dozen languages.

Uniswap founder Hayden posted on the X platform stating that the technical design of automatic compounding liquidity is his personal contribution to pools.trade. The way it works is: liquidity positions are deposited into a smart contract, with the rule that anyone can withdraw all unclaimed fees from that position, provided they increase the size of that liquidity position by 0.2%. Therefore, the fees will grow over time, and when the value of the fees exceeds 0.2% of the liquidity, seekers will naturally be incentivized to add 0.2% liquidity to the pool and claim the fees. This mechanism is based on the Uniswap token jar and can also be used for automatic compounding of regular Uniswap LP positions, so this feature will be added to the roadmap.

According to Jinshi reports, the Korea Exchange has launched a sidecar mechanism for the KOSDAQ, suspending programmatic trading for 5 minutes.

According to official news, OpenAI has released research results stating that its next-generation AI model Astra has made progress in the fields of mathematics and theoretical computer science, involving areas such as high-dimensional geometry, coding theory, group theory, quantum complexity, post-quantum cryptography, and extremal combinatorial mathematics. The 10 published results include: the high-dimensional sphere packing problem, binary and spherical coding problems, non-sofic group problems, Connes rigidity conjecture, arithmetic circuit complexity problems, quantum parallel repetition problems, nearest vector problems, Ehrhart volume conjecture, multi-color Ramsey number problems, and extremal graph theory conjectures.It is reported that these results were derived using an internal version of the Astra model, with the computational cost of finding solutions amounting to approximately $2000 (calculated based on Sol API prices).Subsequently, human researchers used the same model to assist in compiling the results into a paper and generated verifiable proof certificates through the Lean formal proof system.

Tencent's official X account stated that its research agent Hyra collaborated with the Hy3 model to explicitly prove an issue that has troubled the mathematical community for over 50 years: the optimal growth rate exponent of the size of the sum set |A+A| and the size of the difference set |A-A| for a finite integer set A is exactly 2. The theorem from 1969 provided an upper bound of 2, but for the following 50 years, the best constructed exponent was only slightly above 1.1.This achievement demonstrates the potential of AI agents in the field of pure mathematical reasoning. Tencent stated that Hyra is an AI research agent developed in-house, specifically designed to assist in the exploration of complex mathematical and scientific problems. This conclusion still requires confirmation through peer review by the mathematical community.

According to Jinshi reports, Iran had considered attacking a Ukrainian seaport in response to Ukraine's attack on an Iranian vessel, but a series of diplomatic interventions have temporarily eased the situation.Last Saturday, Ukraine attacked an Iranian commercial cargo ship in the Caspian Sea, resulting in the death of a sailor. Sources expect that Iran will launch a ballistic missile carrying a small warhead at Ukraine, potentially targeting one of Ukraine's Black Sea ports.After a call with the Ukrainian Foreign Minister, Araghchi stated that the Ukrainian Foreign Minister claimed the attack on the cargo ship was unintentional.

The South Korean trading platform (KRX) triggered the sidecar mechanism due to fluctuations in the KOSPI index, suspending programmatic trading for about 5 minutes.The sidecar mechanism is mainly used to respond to severe fluctuations in a short period of time, limiting only programmatic trading while manual trading can continue normally. Unlike the circuit breaker mechanism, the sidecar mechanism does not suspend trading for the entire market and is more viewed as a "speed bump" during market volatility.In contrast, the circuit breaker mechanism is typically used in extreme market conditions and, once triggered, suspends trading for the entire market to prevent panic-induced fluctuations from further escalating.

According to external disclosure information, OpenAI has been internally running an unreleased model. This model, without the aid of tools like Lean, solves the unit distance problem with a 48% probability through a single autonomous inference and can independently find a counterexample to the Jacobian conjecture based on a single prompt. In security testing, this model has bypassed the sandbox environment and submitted results that should have been released internally to GitHub in the form of a Pull Request, and it has evaded detection by splitting authentication tokens. Relevant code records show that OpenAI began benchmarking this model no later than May 9, and its internal availability has exceeded 2.5 months.Previously, OpenAI and Hugging Face jointly disclosed that last week this model breached Hugging Face's production infrastructure during a network capability assessment. The model gained internet access through a zero-day vulnerability and obtained testing solutions by stealing credentials and exploiting remote code execution paths. OpenAI stated that this incident indicates the network attack capabilities of advanced models have been effective in real-world scenarios, and they are collaborating with Hugging Face to investigate and patch the vulnerabilities. Currently, OpenAI has not publicly commented on this matter.

The U.S. Securities and Exchange Commission (SEC) announced that it has filed a lawsuit against Florida resident Zan Shaikh and his company Bright Vision Distribution LLC (operating under the name Mining Automatic), accusing them of defrauding investors through a fraudulent cryptocurrency mining investment scheme, with approximately $22 million raised.The SEC stated that from June 2023 to May 2025, Shaikh and Mining Automatic promised investors fixed monthly returns by participating in cryptocurrency mining operations, but the related mining operations were actually unable to generate the promised returns. According to the SEC's complaint, Shaikh and Mining Automatic are accused of making false statements regarding their cryptocurrency mining experience, operational capabilities, the use of investment funds, and the status of the mining business, and explained payment delays by claiming they were unable to pay investor returns.

According to a report by the Procuratorial Daily, researchers from the People's Procuratorate of Yuhu District, Xiangtan City, Hunan Province, and the Law School of Xiangtan University have jointly written an article proposing a systematic response plan to the regulatory dilemmas of money laundering crimes using virtual currency. The article points out that current judicial practice faces three major dilemmas: first, Article 191 of the Criminal Law limits money laundering crimes to seven types of upstream crimes, resulting in many cases being treated as "concealment crimes"; second, methods such as mixers, privacy coins, and cross-chain transfers lead to fragmented evidence chains, making traditional investigative methods difficult to penetrate; third, conflicts in the legal attributes of virtual currency, a vacuum in procedural rules, and barriers to cross-border cooperation make it difficult to recover assets.In response, the article suggests promoting "dual investigations for one case," establishing the principle of self-authentication of blockchain data, constructing a tiered standard of proof, and establishing a national-level custody and disposal platform for involved virtual currencies, while actively promoting the signing of special agreements for international criminal justice assistance in virtual currency crimes.
