first_img Analysis: The significant net outflow of BTC spot ETFs from May to July reflects the absence of institutional buying, and the market may have entered the clearing tail end

On-chain data analyst Murphy stated that this cycle is significantly different from the past due to the influx of traditional institutional funds brought in by the BTC spot ETF. He pointed out that the net flow of the ETF essentially records the subscription and redemption results of authorized participants (AP) in the primary market. It will only translate into net inflows or outflows in the data when the selling pressure in the secondary market continues to push the ETF price away from its net asset value and exceeds the arbitrage cost line.Murphy analyzed the data from glassnode and noted that from January to February, the market showed "high trading volume + slight net outflow," indicating that although there was obvious panic selling at that time, there was still a large amount of buying support. In contrast, from May to July, the market exhibited "low trading volume + significant net outflow." The more core signal was not a significant increase in selling pressure, but rather the absence of marginal buying, leading to the ETF consistently trading at a discount and resulting in AP redemptions.He believes that this stage is more likely to reflect a second round of "surrender" at the institutional level, which typically belongs to the tail-end clearing pattern of the market, and judges that this may provide new layout opportunities for retail investors, although the duration cannot be clearly determined by the current data.

Over 1.2 million leveraged retail accounts in South Korea have triggered margin calls, with approximately 320,000 to 360,000 accounts being fully liquidated by brokers

According to Yicai, global chip stocks faced a Black Monday. On that day, during the Asian trading session, rising geopolitical tensions in the Middle East suppressed risk appetite, with SK Hynix plunging over 15% on the Korean Exchange, marking the largest single-day drop in 18 years; the South Korean benchmark index KOSPI fell more than 9% in a single day, retreating 25% from its historical high on June 22.Data from the Financial Supervisory Service of Korea shows that the total amount of forced liquidations across the entire South Korean market reached 344.2 billion won in a single day, the largest scale of credit liquidation this year. Retail investors accounted for 92% of leveraged positions, referred to as "ant investors," who made full bets on memory chips and have very weak capacity to withstand volatility. As of Monday, over 1.2 million leveraged retail accounts in the entire South Korean market had reached the margin call line. Among them, approximately 320,000 to 360,000 accounts have been fully liquidated by brokerages, resulting in the loss of principal, with some accounts even owing debts to brokerages.Institutions believe that the short-term Gamma effect of leveraged shorts in South Korea cannot be eliminated, and the trillion-won level of leveraged selling pressure has not been fully cleared, with the risk of volatility still unresolved. However, this round of decline is not a reversal of the industry's fundamentals but rather a concentrated deleveraging event following macro shocks faced by crowded high-position leveraged trades.

Detailed explanation of the security item change event released by Gate: Confirm that the applicant has a good grasp of highly matching external information and is advancing on-chain analysis and asset tracking procedures

Gate recently released a detailed verification statement regarding the security item changes and fund loss incident reported by customer 9****6. After an internal review, the platform confirmed that the applicant submitted materials highly matching the customer's account, including Email, phone number, real-name information, transaction records, and Alipay screen recordings. The platform pointed out that the Alipay screen recording required access to the customer's Alipay account and successfully passed multiple identity verifications, indicating that the applicant not only possessed account information but also obtained the customer's external real-name information, Alipay account, and device permissions in advance.The platform emphasized that its security unbinding review implements a four-fold verification process of "multi-channel advance notification + system risk control preliminary screening + manual multi-layer review + time protection." After notifying the customer through dual channels, the application was processed only after waiting two days without objections, and a 24-hour withdrawal prohibition protection was imposed after modification. Upon investigation, there were no information leakage logs within the platform, and some sensitive identity information provided by the applicant was external information previously unknown to the platform.Regarding fund recovery, the platform has sorted out the flow of funds and collaborated with multiple departments to conduct on-chain analysis and asset tracking, currently coordinating with third parties like Tether to advance the freezing process, and will cooperate with judicial investigations in the future. The platform advises customers to conduct comprehensive security reinforcement on their devices and expresses regret that the customer did not contact the platform within the three-day notification period.

Vitalik's post details the entire technical tree behind the mainline of the confusion protocol (iO)

Vitalik Buterin published an article titled "Obfuscation: building the final boss of cryptography (Part I)", systematically outlining the entire technical tree behind the mainline of the obfuscation protocol (iO). The article points out that obfuscation technology can transform programs into "encrypted programs", allowing computations on plaintext inputs while hiding internal logic. Theoretically, it can achieve "trustless trusted third parties", and when combined with blockchain, it can build nearly trustless voting systems, auction protocols, and various other applications. However, the current iO scheme, while technically polynomial time, incurs enormous practical overhead, with expected runtimes exceeding the lifespan of the universe.The article details the construction process of lattice-based iO, covering the stacking of primitives such as fully homomorphic encryption (FHE), attribute-based encryption (ABE), obfuscated circuits, function encryption, and XiO. Vitalik stated that the field has moved from "impossible" to "provably secure" over the past decade, but there remains a significant gap to practical application. He proposed three future paths: further optimizing the existing lattice-based route, adopting bolder cryptographic assumptions to simplify constructions, or exploring entirely new assumptions that are completely different from lattices, emphasizing that if any direction succeeds, it will largely "solve cryptography", enabling any protocol describable by an ideal trusted third party to be securely implemented.
