Introduction to the World of Decentralized Identifiers
The Web3 revolution has brought new approaches to managing personal data, and one of the most promising technologies is the (decentralized identifier). When Sam Altman, the head of OpenAI, introduced Worldcoin, it became a

Blockchain is revolutionizing research. Decentralized Science (DeSci) is not just a technological trend but a rethinking of how scientific projects are funded, data is exchanged, and scientists worldwide collaborate. Traditional science faces structural problems: centralized

Support and resistance levels are essential skills that traders must learn in the volatile cryptocurrency market. They help traders identify reversal and breakout points, thereby improving the quality of trading decisions. Through various technical analysis methods, such as observing high and low points, trend lines, and Fibonacci ratios, traders can better grasp market trends. These concepts are not only the foundation of trading strategies but also provide effective solutions for dealing with price fluctuations.

Historical Origin and Relevance
Over a hundred years ago, Charles Dow laid the foundation for one of the most influential approaches to market analysis. His works, published in the Wall Street Journal in the early 20th century, were later systematized by researchers such as William Hamilton. Today, this approach remains relevant.

In the Bitcoin ecosystem, the Lightning Network is a solution that fundamentally changes transaction practices. It is a second-layer (Layer-2) protocol operating on top of the main Bitcoin blockchain, enabling users to work with digital assets much more efficiently.
Why Lightning

Cryptocurrency payment cards are rapidly becoming mainstream tools in the digital finance sector. The core value of these cards lies in their ability to facilitate purchases directly with virtual assets, eliminating the need for cumbersome pre-exchange processes. Compared to traditional manual exchange methods, modern payment cards enable automatic conversion at transaction points, and this seamless experience is driving rapid market expansion.
According to research data from Proficient Market Insights, the global cryptocurrency payment card market is expected to expand at a compound annual growth rate (CAGR) of 8.8% from 2024 to 2031. The growth in user base is equally remarkable — last year, the user scale increased by 150%, reflecting the market's hot demand.
This growth is driven by three factors: ease of use, attractive reward mechanisms, and relatively low transaction fees. For users seeking the best crypto card, the key is to find one that best suits their needs.

In cryptocurrency trading, market stop-loss orders and limit stop-loss orders are two main risk management mechanisms. Market stop-loss orders are executed immediately at the market price when the stop-loss price is reached, while limit stop-loss orders only execute once the market price reaches the limit price. Understanding the difference between these two helps better manage risk and optimize trading outcomes.

The golden cross is an important technical signal in cryptocurrency trading. When the 50-period moving average crosses above the 200-period moving average, it indicates that market sentiment is shifting from pessimistic to optimistic. However, this signal should be combined with market conditions, trading volume, and other indicators for comprehensive analysis to reduce risk and improve success rates. Proper risk management and strategic capital allocation are also essential.

This article discusses the importance of stop-loss orders in cryptocurrency trading, focusing on the execution mechanisms and risks of conditional market orders and conditional limit orders. Conditional market orders ensure high fill rates but offer no price guarantee, making them suitable for urgent stop-loss situations; conditional limit orders provide price control but may not be filled, making them more appropriate for conservative trading. The choice should be based on market conditions and risk preferences, and attention should be paid to slippage risks.

Starting from the identity management revolution
One of the most talked-about phenomena in the crypto market this year is the surge of the Worldcoin project founded by Sam Altman among user communities. The popularity of this project has suddenly brought the identity verification technology, which was previously overlooked in the Web3 ecosystem, into the spotlight. The success of Worldcoin demonstrates that underpinned by blockchain technology, digital identity management has moved from theory to practice.
As Web3 and decentralized digital identity(Distributed Digital Identity,

Blockchain has long struggled with a fundamental contradiction: maintaining decentralization while achieving the transaction throughput needed for mass adoption. Layer-2 solutions, particularly rollups, promised to break this deadlock by processing transactions off-chain while maintaining security g

Since Satoshi Nakamoto first introduced Bitcoin in 2008, the digital currency ecosystem has undergone tremendous transformation. Originally conceived as a peer-to-peer electronic cash system, it has now evolved into a vast industry covering multiple application scenarios. By 2025, blockchain technology has moved beyond the exploration phase and become the infrastructure supporting global transactions. Decentralized payment networks enable direct transfers by eliminating intermediaries, leveraging cryptographic algorithms and consensus mechanisms to fundamentally resist fraud. This architecture not only ensures the immutability of transactions but also provides a solid foundation for auditing and accountability.
How Blockchain Reshapes the Transaction System
The changes brought by next-generation payment technologies are multi-dimensional:
- Transaction speed and cost optimization: Compared to traditional financial channels, blockchain significantly shortens processing cycles while reducing operational expenses
- Enhanced security: Advanced cryptographic mechanisms greatly reduce the risks of digital transactions
- Complete transparency:
