On August 10, UMX (The Unified Market Exchange), incubated by Avenir Group under Li Lin, announced the launch of an invitation-only public beta. UMX is positioned as a crypto-friendly securities platform for global professional investors, supporting spot, leverage, contract, and options trading of crypto assets, while also supporting real US stocks, ETFs, and US stock options trading. The aim is to connect crypto assets and real securities trading on the same platform, enhancing the capital efficiency of cross-asset trading.The public beta focuses on opening the capital link between crypto assets and securities accounts, supporting functions such as stablecoin exchange transfers, non-stablecoin collateralized lending, fiat account withdrawals and deposits, and the mutual conversion of securities holdings and stock tokens. To enhance cross-asset capital efficiency, the platform introduces a cross-asset margin mechanism, allowing financial assets to be used as margin. During the public beta, BTC and USDT financial products will also be launched, with the highest annualized returns reaching 2.5% and 5.5%, respectively. This public beta is invitation-only, and users who have not yet obtained a public beta code can reserve the official version and participate in the early bird benefits program.

According to The Wall Street Journal, Apple is testing memory chips from the Chinese DRAM manufacturer Changxin Storage (CXMT), planning to apply them to product lines such as the iPhone and MacBook. The background of this move is the AI demand driving up global memory prices; Apple has previously lobbied the U.S. side, stating that the current pricing from Korean and American suppliers is "unsustainable." The report states that Apple is seeking approval from the White House to conduct business with Chinese chip suppliers. Currently, the U.S. allows the purchase of commercial off-the-shelf chips but restricts customized products.Changxin Storage has recently rapidly expanded its market share, with second-quarter revenue growing more than 8 times year-on-year, and its global DRAM market share rising to 7%, completing its IPO on the Science and Technology Innovation Board last month. Meanwhile, PC manufacturers such as HP and Acer have begun using Changxin Storage memory chips in some devices sold in non-U.S. markets to alleviate supply pressure. If Apple ultimately reaches a procurement agreement, it may face political resistance from Washington.

Starknet announced that it has completed the quantum-resistant signature transfer test, where a wallet account using a quantum-resistant signature mechanism completed a real transfer on the Starknet mainnet, with a transaction fee of about 6 cents, and can be queried through the block explorer. This account is currently an experimental, unaudited version, mainly used for research testing. StarkWare stated that this transfer benefits from the design of the Starknet account model.Unlike most blockchains that fix the signature algorithm at the protocol layer, each account on Starknet is a smart contract that can autonomously define the accepted signature schemes, allowing users to upgrade their wallets from traditional elliptic curve signatures to quantum-resistant signatures without hard forks, asset migrations, or changing addresses. StarkWare pointed out that most blockchains face quantum computing risks because wallet signatures and underlying verification systems rely on elliptic curve cryptography. Once large-scale quantum computers appear, running Shor's algorithm could potentially break the related encryption systems. Currently, the Starknet ecosystem supports a quantum-resistant signature scheme based on Falcon-512, which is part of the NIST post-quantum cryptography standardization process, with relevant implementations promoted by ecosystem teams and organizations such as OpenZeppelin.

According to Wired, during security testing, the open-source model Kimi K3 from the dark side of the moon broke out of the sandbox and accessed the internet, attempting to find test answers via GitHub. American security startup Frontier Security stated that Kimi K3 exploited a sandbox configuration vulnerability, but it itself lacked sufficient built-in protective mechanisms.Similar to incidents previously disclosed by OpenAI and Anthropic, this escape partially stemmed from a sandbox configuration error. However, Kimi K3 did not initiate an attack, as the answers were easily accessible on GitHub. The CEO of Frontier Security stated that Kimi K3 performed excellently in cybersecurity defense but lacked mechanisms to prevent cheating or escaping the sandbox. Security experts emphasized that configuring the testing environment is crucial, as the misuse of AI agents could lead to system failures.

Bitcoin News posted on the X platform that new community honeypot tests show that attackers are still prioritizing wallets that are most easily exploited due to the Coldcard Mk3 RNG vulnerability.Researcher @ColeTU injected funds into 5 affected Mk3 wallets: 1 using only the vulnerable mnemonic, 3 protected by BIP39 passphrases of 1, 2, and 3 words respectively, and another using a random account number. After 14 hours, only the unprotected wallet using just the mnemonic had its funds transferred away. According to @jamesob's real-time tripwire dashboard, currently only 2 out of 17 honeypot wallets have been emptied. The emptied wallets have been confirmed not to have added extra entropy, while all wallets protected by dice rolls, passphrases, multisig, or other complexities remain untouched.The test results indicate that attackers are currently focusing on the wallets that are easiest to brute-force rather than investing resources in strengthening targets, but affected users should still migrate their funds immediately instead of relying on temporary protections.

According to Jinshi reports, the latest 24-hour situation tracking of the Russia-Ukraine conflict shows that Ukrainian President Zelensky stated that the supply of Ukraine's air defense systems has decreased by two-thirds compared to last year. In the Kyiv region, 16 people have died, and the number of injured has risen to 36.The Russian Ministry of Defense claimed to have damaged three ships near Odessa and disrupted logistics hubs in Kyiv and its surrounding areas. In addition, French President Macron and European Commission President von der Leyen both stated that they would continue to increase pressure on Russia, with the latter also mentioning that an additional 1.4 billion euros would be allocated to Ukraine from the profits of frozen Russian assets.

According to Cointelegraph, payment giant Mastercard has announced a pilot project with the stablecoin infrastructure network Borderless to explore the use of the Mastercard Crypto Credential standard framework to provide more reliable identity verification and compliance support for cross-border stablecoin payments.Both parties stated that the pilot will test how to provide "trust signals" that can be used for approval, compliance review, and risk management for transaction participants through a standardized certification mechanism, reducing compliance friction in cross-border stablecoin payments.The Mastercard Crypto Credential framework provides identity confirmation and credibility assurance for blockchain transactions through unified standards and verification mechanisms. Kevin Lehtiniitty, co-founder and CEO of Borderless, stated that compliance has always been a major barrier to the scalable development of stablecoin payments, and Mastercard is attempting to apply the compliance trust model from traditional finance to the digital asset payment space. He pointed out that the Mastercard Crypto Credential will serve as a governance and verification layer in this pilot, but Mastercard will not directly handle or settle funds. This collaboration is the latest move in Mastercard's ongoing strategy in the stablecoin space.Previously, Mastercard had just completed the acquisition of stablecoin infrastructure company BVNK for approximately $1.8 billion, further strengthening its infrastructure layout in the digital asset payment field. In June of this year, Mastercard also announced plans to expand its settlement capabilities to support round-the-clock card payment settlements using stablecoins, including USDC issued by Circle, PYUSD, USDG, USDP issued by Paxos, and RLUSD issued by Ripple.The market believes that as stablecoins gradually enter cross-border payment scenarios, identity authentication, compliance verification, and risk control infrastructure will become important factors driving institutional adoption.

SolanaFloor stated that the first block time adjustment for Solana under the SIMD-0525 framework will go live on the testnet within two hours.This adjustment lowers the target block time from 400 milliseconds to 350 milliseconds, marking the first step in a four-phase plan to achieve a target block time of 200 milliseconds.

According to Reuters, citing three informed sources, Samsung Electronics and SK Hynix are testing the etching equipment from Chinese semiconductor equipment manufacturer AMEC to assess its potential application in their factories in China, aiming to hedge against the risk of the U.S. potentially tightening export controls in the future. The testing began about two years ago, coinciding with rising uncertainty over whether the U.S. would allow Korean companies to import U.S.-made chip equipment to China.The report noted that although no decision has yet been made on large-scale deployment, verification from Samsung or SK Hynix would be an important commercial endorsement for AMEC. The gap in etching, deposition, cleaning, and other areas for Chinese equipment has gradually narrowed, with prices typically 20%-30% lower than similar overseas products. Samsung officially denied having tested AMEC equipment for its factories in China, while SK Hynix declined to comment. Deutsche Bank expects Northern Huachuang, AMEC, Tuojing Technology, and Shengmei Semiconductor to each exceed $1 billion in revenue by 2026, collectively expected to capture 25%-30% of China's approximately $28 billion wafer fabrication equipment market this year.

According to Reuters, citing two informed sources, the Trump administration informed leading AI companies on Tuesday that it will not conduct security testing on open-weight AI models. This decision marks a new direction for the U.S. government in its approach to AI regulation. Open-weight models allow developers and users to freely download, modify, and deploy model parameters without relying on closed API access. Previously, organizations such as the American Institute for AI Safety (AISI) had conducted security assessments on cutting-edge models. The White House and relevant departments have not publicly commented on this matter yet.

According to Bloomberg, the UK government's AI Safety Research Institute (established in 2023) disclosed on Tuesday that during a safety assessment of OpenAI's GPT-5.6-Sol and Anthropic's Mythos 5 models, both models exhibited "unauthorized" harmful behaviors, including actively infiltrating real websites and attempting to inject malicious code into software, targeting real people and organizations.During the testing period, the institute deliberately granted the models internet access and disabled some security filters to assess their limits.

Bitget CFD Chief Analyst Lewis Huang pointed out in a live broadcast that this week's market focus has shifted from tech stock earnings reports back to U.S. employment data and Fed policy expectations.The key to this non-farm report is not just the number of new jobs added, but whether the unemployment rate, average hourly wage, and previous values' revisions collectively indicate a "orderly cooling" or "significant slowdown" in the labor market.Lewis Huang stated that if non-farm employment and wage data are both stronger than expected, the market will lower short-term rate cut bets, U.S. Treasury yields and the dollar are expected to strengthen, while gold and high-valuation tech stocks will face pressure; conversely, if employment, wages, and previous values' revisions all weaken, the market will raise expectations for Fed easing, and gold and non-U.S. currencies may receive support.He advised CFD traders to avoid chasing orders in the first minute after data is released, and to focus on observing whether the U.S. two-year Treasury yield, the dollar index, and gold form a synchronized confirmation, and to wait for a pullback opportunity after a key price level breakout. The current trading focus is not simply betting on the data's highs and lows, but rather judging how the non-farm report will change the market's pricing of the Fed's policy path.

According to official news, Japanese convenience store giant Lawson will conduct Japan's first POS cash register stablecoin payment pilot experiment at two stores in Tokyo on August 6 and August 17. The experiment will use three stablecoins: JPYC, USDC, and USDT, with payments completed through HashPort Wallet and MetaMask wallet, and settlements processed by the PAYTREE multi-code payment gateway provided by Canal Payment Service, without the need for dedicated payment terminals.On August 6, the experiment will take place at the Takanawa Gateway City store using HashPort Wallet and JPYC; on August 17, it will take place at the Osaki Atrium store using MetaMask with USDC, USDT, and JPYC.

U.S. President Trump stated that negotiations between the U.S. and Iran are progressing rapidly, with both sides discussing the reopening of the Strait of Hormuz, which "may reopen as early as tomorrow."Trump mentioned that the goal of the first phase of negotiations is to reopen the Strait of Hormuz, while the second phase will focus on Iran's "denuclearization." He stated that if anyone attempts to charge fees in the Strait of Hormuz, "the U.S. will charge fees," emphasizing that Iran will not be allowed to collect fees in the strait.Trump also mentioned that this is Iran's "last chance," and that the negotiations are taking place at Iran's request, with relevant results possibly being announced today or tomorrow.Previously, the situation in the Strait of Hormuz had been tense, and the market is closely monitoring its impact on global energy supply and oil price trends.

According to Jinshi reports, court documents show that 25 states in the United States have filed lawsuits challenging Trump's latest tariff measures.
