The Expansion of USDt and the Rise of XAUt: A New Landscape in the Stablecoin Market
Recently, Bloomberg pointed out in a monthly report that the growth momentum of USDt is strong, and surpassing Ethereum seems to be just a matter of time. In fact, since March 12, factors such as the demand for margin trading from cryptocurrency traders, the development of the gray industry, and the demand for the US dollar in certain countries and regions have jointly driven the rapid increase in the market value of USDt.
However, while USDt is receiving much attention, other assets issued by Tether that are pegged to stablecoins are rarely inquired about. According to official data, apart from USDt, Tether has also issued stablecoins pegged to the Euro, Renminbi, and Gold, namely EURt, CNHt, and XAUt.
Among them, EURt was issued as early as 2014, but its current market value is only about 45 million euros. CNHt was launched in September 2019, with a market value of about

When designing the physical laws of a virtual world, it is necessary to balance complexity and feasibility, considering the passage of time, the form of rules, and the scope of application. Synchronous and asynchronous time each have their advantages and disadvantages, and the open and closed forms of physical laws affect both engagement and computational efficiency. Additionally, a reasonable division of areas can help optimize resource use, creating an engaging environment with manageable computational load.

Global Economic Policy Barometer: The Influence and Outlook of the Jackson Hole Annual Meeting
Every year at the end of summer, the world's economic community focuses on an important event—the Jackson Hole Economic Symposium. This annual event attracts central bank officials, economists, financial market participants, and media representatives from around the globe to discuss economic policies and market trends.
This year's seminar will be held from August 22 to 24, with the theme "Reassessing the Effectiveness and Transmission of Monetary Policy." After years of a low-interest-rate environment, the U.S. economy has shown remarkable resilience in the context of significant interest rate hikes, sparking widespread attention and discussion. Despite widespread market predictions of a possible recession, data shows that the U.S. economy seems to ignore these forecasts and remains strong.
Low-interest mortgages held by homeowners and refinancing conducted by companies using ultra-low rates both reflect that the impact of monetary policy on the real economy is not as significant as it has been in the past. Jackson Hole Annual Meeting

Ethereum smart contracts Gas Optimization Practical Guide
The Gas fees on the Ethereum mainnet have always been a tricky issue, especially during times of network congestion. During peak periods, users often have to pay high transaction fees. Therefore, optimizing Gas fees during the smart contracts development phase is crucial. Optimizing Gas consumption can not only effectively reduce transaction costs but also improve transaction efficiency, providing users with a more economical and efficient blockchain experience.
This article will outline the gas fee mechanism of the Ethereum Virtual Machine ( EVM ), the core concepts related to gas fee optimization, and best practices for optimizing gas fees when developing smart contracts. It is hoped that this content will provide inspiration and practical assistance to developers, while also helping ordinary users better understand the operation of gas fees in the EVM, collectively addressing the challenges in the blockchain ecosystem.

From social data to AI brains: What kind of AI network will Port3 Network create for the Web3 world?
1. Introduction
In the world of Web3, data is transforming from static information into dynamic assets. In particular, user social behavior data is becoming the most valuable yet underdeveloped "digital mineral" in the AI era. The enormous value contained in social data generated every minute has not yet been fully explored.
We see that the reality of Web3 is fragmented: on one hand, we have witnessed explosive growth of vertical protocols such as DeFi, NFTs, and GameFi, with users generating a large amount of behavioral data both on-chain and off-chain; on the other hand, this data is scattered across isolated DApps, transaction records, and social platforms, lacking structured integration, making it difficult to build a unified profile and truly utilize it.
At the same time, the rise of AI is rapidly reshaping the entire

Crypto market Q3 macro research report: Alt season signal has appeared, institutions are adopting to drive selective bull run outbreak.
1. The macro inflection point has arrived: regulatory warming and policy support resonate.
As the third quarter of 2025 begins, the macro landscape is quietly changing. The policy environment that once pushed digital assets to the margins is now transforming into a systemic driving force. Against the backdrop of the Federal Reserve ending the interest rate hike cycle, fiscal policy returning to a stimulus track, and the accelerated construction of a "accommodative framework" for global encryption regulation, the crypto market is on the eve of a structural reassessment.
First, the macro liquidity environment in the United States is entering a critical turning point. Although the Federal Reserve continues to emphasize "data dependence", the market has reached a consensus on interest rate cuts within 2025. The divergence between the lagging dot plot and the leading expectations of the futures market is increasingly widening. This expectation gap has opened an upward channel for risk assets, especially digital assets.
At the same time, efforts from the fiscal side are also unfolding. For example, certain
