The institution also completely exited its positions in Blackstone, the S&P 500 ETF, Mellanox Technologies, and Danaher, among others.

Tether Gold completed an audit by the Big Four accounting firms, with reserve gold valued at 2.246 billion USD

Tether announced that KPMG U.S. has completed an independent audit of the financial statements of TG Commodities, the issuer of Tether Gold (XAU₮), as of December 31, 2025, and issued an unqualified opinion. The audit shows that XAU₮ is fully backed by physical gold. This is the second stablecoin under Tether to complete an audit by one of the Big Four accounting firms, following Tether International, the issuer of USDT, in August of this year.During the audit, KPMG conducted a physical count and verification of each gold bar backing XAU₮, rather than relying solely on confirmations from custodians. As of December 31, 2025, TG Commodities holds 520,089.350 ounces of pure gold, valued at $2.246 billion, corresponding to the issued 520,089.300 XAU₮.The gold is stored in Swiss vaults and meets the London Good Delivery standards, with ownership belonging to the token holders, where each token corresponds to an indivisible ownership of specific gold bars. The company also hires an independent third party to conduct quarterly sampling tests of the gold bars.CEO Paolo Ardoino stated that XAU₮ is expected to become the first true competitor in the gold ETF market, as gold can be settled instantly, with lower custody costs and higher transparency. CFO Simon McWilliams mentioned that auditing the largest and most complex USDT and XAU₮ is paving the way for a comprehensive audit of the entire company.

DTCC: Tokenization services will integrate with Solana, scheduled to launch in the second half of 2027

According to PR Newswire, the Depository Trust & Clearing Corporation (DTCC) announced plans to integrate its Tokenization Service (DTCC Tokenization Service, DTS) with Solana's Layer 1 network, allowing eligible assets held by DTC to be converted into token form and to gain corresponding token lifecycle functionalities. This integration is expected to go live in the second half of 2027.DTS was officially launched on October 28, and this integration with Solana is an extension of its "multi-chain strategy." DTCC stated that after the integration, DTC tokenized assets will retain the same investor protections, ownership rights, and regulatory safeguards as traditional held securities, while enhancing liquidity, collateral liquidity, and capital efficiency.DTCC President and CEO Frank La Salla stated that this brings regulated DTC tokenized securities to another mainstream blockchain ecosystem; Brian Steele, President of Clearing and Securities Services, emphasized that the service is a "secure, interoperable, and market-neutral" infrastructure; Nadine Chakar, Global Head of Digital Assets at DTCC, mentioned that interoperability is key to the scalability of digital markets; Nick Ducoff, General Manager of Institutional Business at the Solana Foundation, stated that after the integration, tokenized securities can be settled and circulated like other on-chain assets.

Analysis: The process of deleveraging has accelerated, and Binance's Bitcoin open interest has decreased by 17% in one month

CryptoQuant analyst Darkfost stated that within less than a month, the open interest of BTC on the Binance platform has decreased from 10.6 billion dollars to 8.8 billion dollars, a drop of 17%. Meanwhile, its 180-day moving average has risen from 8.4 billion dollars to 8.6 billion dollars. As the open interest falls below the moving average, new signals of deleveraging are emerging in the market. In a bull market phase, this signal typically appears when market corrections are nearing their end, reflecting that traders are reducing their leveraged exposure, which includes both voluntary liquidations and forced liquidations due to insufficient margin.Aside from the fact that this process may last for months in a bear market, a similar signal last appeared in June of this year when the BTC price was below 60,000 dollars, subsequently rebounding to above 87,000 dollars, with an increase of over 45%. Currently, as the open interest declines, the market is also experiencing large-scale liquidations. Low volatility seems to encourage some traders to take on higher risks to compensate for the insufficient returns brought about by the narrowing price fluctuations, making them more susceptible to market reversal shocks. Over the past three months, the monthly liquidation scale on Binance has reached new highs since 2021: over 1.4 billion dollars in August, 1.1 billion dollars in September, and 1.3 billion dollars in October. This trend appears to continue into November, with the liquidation scale exceeding 520 million dollars before the end of the first half of this month.These data highlight the potential losses that leveraged trading can bring to investors. In a market environment with low volatility and shrinking trading volume, blindly increasing risk exposure due to a lack of patience can quickly lead to heavy costs. However, the deleveraging phase also helps improve the market environment. Reducing leveraged positions can lower the risk of cascading liquidations, allowing spot demand to play a greater role in market pricing, thereby helping Bitcoin establish a more robust market structure.

Chainstack disclosed that it suffered an AI-driven cyber attack at the end of October, resulting in the exposure of customer account information

Blockchain infrastructure service provider Chainstack disclosed that it experienced an AI-driven cyber attack from October 26 to 31, 2026. The attacker accessed the development environment through an unmodified default administrator credential and a Grafana instance without single sign-on protection, subsequently gaining cluster administrator privileges via an unauthenticated MCP tool server and stealing credentials through an automated platform, ultimately accessing the production environment to read the customer database.This incident resulted in the exposure of customer account information, including organization names, account holder names, member email addresses, and password hashes. The attacker also had access to systems containing node credentials, although there is no evidence that they were read; however, Chainstack still urged customers to rotate their node credentials. Chainstack stated that customer-facing services operated normally during the incident, and customer nodes, consoles, and APIs were not modified. Investigations revealed that the attacker used the open-source framework ARTEX, with no evidence found of exploiting software vulnerabilities. Chainstack has cut off the attack access path and requested customers to change passwords, rotate node credentials, regenerate platform API keys, and remain vigilant against phishing information.

first_img Ming-Chi Kuo: Jensen Huang may find it difficult to withdraw unscathed, NVIDIA should prepare for succession

Tianfeng International Securities analyst Ming-Chi Kuo stated that Jensen Huang's importance to NVIDIA lies in his ability to transform technologies deemed feasible by engineers into products that the company must invest resources in, take risks on, and deliver. He believes this provides the supply chain with strong order visibility and a willingness to cooperate with aggressive specification upgrades; this move will also force competitors to follow suit, thereby driving technological upgrades and supply chain investments across the entire AI industry.Kuo mentioned that compared to providing order visibility to the supply chain, deciding on and implementing aggressive specification upgrades is more challenging. Jensen Huang does not need to be the person within NVIDIA who understands new technologies such as HVDC, CPO/NPO, or CCL/PTFE the best; his value lies in weighing strategy, organization, technology, and supply chain simultaneously, and making decisions and allocating resources quickly. He indicated that based on the information currently available, it is difficult for Jensen Huang to step back completely; if so, the actual approach may be to gradually reduce NVIDIA's reliance on Huang's personal decisions while preparing a succession plan. Two things worth observing in this process are whether NVIDIA can continue to develop new products and technologies as efficiently as before, and how competitors will respond. He stated that supply chain research will be an important basis for judging the direction of AI technology and investment.
