Academy of Social Sciences Expert: Changxin Technology's overseas on-chain transactions may weaken the domestic capital market's dominance in pricing technology assets

According to Caixin, Zhao Yao, a special researcher at the Payment and Clearing Research Center of the Financial Research Institute of the Chinese Academy of Social Sciences, stated that recent offshore digital asset platforms have launched on-chain trading products around Chinese technology companies such as Changxin Technology. This indicates that global digital financial platforms are creating trading exposure around high-quality Chinese technology assets, organizing price expectations, trading liquidity, and cross-border capital entry in advance. Although these products do not correspond to A-share equity, they are synthetic perpetual contracts or pre-market perpetual contracts settled in stablecoins such as USDC and USDT. However, if offshore platforms take the lead in forming a continuous trading market for technology assets, it may weaken the pricing dominance of domestic capital markets over technology assets.Zhao Yao suggested accelerating the construction of digital financial infrastructure for the renminbi, promoting the coordinated development of tokenized deposits by commercial banks, wholesale CBDC, and tokenization of technology assets, and exploring pilot projects for technology asset tokenization in Hong Kong to enhance the capital organization capability and international pricing power of the renminbi in global technology financial competition.

Zilliqa Ledger application exposes serious vulnerability, signing 5 native transactions may leak private keys

Zilliqa stated that there is a serious random number generation vulnerability in the Zilliqa Ledger application, affecting the Schnorr signatures of native non-EVM Zilliqa transactions. Attackers can recover the signer's private key from the biased temporary random numbers using only publicly available on-chain data.Any account that has signed and broadcasted about 5 or more native transactions through the Zilliqa Ledger application should be considered compromised. Since the related signatures are permanently recorded on the chain, subsequent updates to the application cannot eliminate the risk, and the affected private keys must be deactivated. EVM transactions and development tools such as zilliqa-js, gozilliqa-sdk, and pyzil are not affected.The vulnerability arises from the application selecting the wrong 32 bytes when copying the random number, retaining 8 bytes of zero padding and losing 8 bytes of entropy, resulting in each random number having a maximum of 64 bits fixed to zero. Attackers can use 5 or more affected signatures to recover the private key within seconds using ordinary hardware. Zilliqa observed suspected active exploitation on July 19 and confirmed the root cause on July 21.Zilliqa has suspended native transactions to prevent further loss of funds and is preparing a revised application with Ledger. However, the revised version cannot protect the exposed keys, and affected users should not transfer assets on their own but wait for the official announcement of a coordinated disposal plan.

The National Development and Reform Commission released the "Action Plan for the Cooperative Development of Artificial Intelligence," proposing eight major actions to promote global AI collaboration

The National Development and Reform Commission officially released the "Action Plan for the Cooperative Development of Artificial Intelligence," aimed at building an open, shared, secure, orderly, and collaboratively governed global artificial intelligence ecosystem. The plan clearly outlines eight core actions, comprehensively promoting deep international cooperation in the AI field from multiple dimensions, including data, computing power, algorithms, talent, and governance. At the foundational level of data and computing power, the action plan emphasizes the need to promote cross-border data flow and build a trustworthy cross-border data space, collaboratively constructing a high-quality corpus; at the same time, it promotes the interconnection of intelligent computing facilities, providing inclusive intelligent computing services to developing countries, and creating low-carbon intelligent computing infrastructure driven by green energy.In terms of industrial empowerment and ecological sharing, the plan encourages the co-construction of an international open-source community for artificial intelligence, promoting the sharing of general large models, basic algorithms, and tool components, and supporting countries in conducting localized innovation based on open-source models. By deepening "Artificial Intelligence +" cooperation, it aims to build a cross-national industrial cooperation platform, promoting the deep application and empowerment of AI technology in fields such as science, manufacturing, healthcare, education, agriculture, and governance. In addition, the plan also proposes the establishment of a joint training mechanism for top digital talent, collaboratively formulating occupational standards and skill certification systems, comprehensively enhancing public literacy, and jointly addressing the structural impacts of AI on employment.Regarding industry rules and technical security, the action plan advocates for the co-construction of rules and standards and collaborative governance for security. All parties will strengthen information sharing on cybersecurity threats and emergency response cooperation, researching ways to enhance the explainability, transparency, and safety of artificial intelligence. Finally, the plan emphasizes adherence to the technological ethics principle of "AI for Good," collaboratively constructing an ethical guideline system dedicated to eliminating algorithmic biases in the forms of racism, discrimination, and others. By promoting international governance cooperation in AI research, it aims to contribute public scientific products to the Global South, effectively serving the United Nations' 2030 Sustainable Development Goals.

The Russian Financial Supervisory Authority will be authorized to monitor all cryptocurrency transactions, with those over 60,000 rubles required to be reported

According to Bits.media, a new draft bill submitted by the Russian government aims to grant the Financial Supervisory Authority the power to monitor all cryptocurrency transactions. For cryptocurrency transactions exceeding 60,000 rubles and foreign trade cryptocurrency transactions exceeding 1,000,000 rubles, the agency will collect complete information such as the full names or corporate names of the payer and payee, wallet addresses, actual addresses, birth dates, and taxpayer identification numbers. Transactions below 60,000 rubles only require the provision of names and wallet addresses.The bill also stipulates that the new limit for digital asset transactions by banks is 1% of the bank group's capital, and banks must hold corresponding funds to cover risks for the purchased cryptocurrencies. The central bank will be authorized to restrict or prohibit specific cryptocurrency operations when they threaten investor interests or may "undermine the stability of the financial system," with the scope extending from non-bank financial institutions to banks. The bill is expected to take effect simultaneously with the main cryptocurrency regulatory legislation, originally scheduled for implementation on July 1, but the review has been postponed. The first deputy governor recently stated that the relevant laws may take effect on September 1.
