Why are your messages available to everyone?
When you send a message through a mobile application, it may create the impression of complete privacy in communication. In reality, however, your message passes through numerous intermediary servers before reaching the recipient. The server sees the recipient, the content, and the time of sending.

The transaction ID (TXID) is the unique identifier for each transaction in the Blockchain, generated through an Encryption Algorithm to ensure the traceability and transparency of the transaction. Users can check the transaction status through the blockchain explorer and can use the transaction ID to diagnose issues or trace the flow of funds. Understanding the transaction ID is crucial for the asset security of users.

Testnets are crucial for blockchain security, allowing developers to test new features in an isolated environment before launch, preventing financial losses and reputational damage. They use virtual tokens, offer faster transaction processing, and invite user participation, thus enhancing safety and reliability in the blockchain ecosystem.

What is hidden behind the abbreviation GDP?
Gross Domestic Product (GDP) is a key indicator of the health of a national economy. This figure reflects the total value of all goods and services produced within a country over a specific time period. From basic bread to high-tech products,

Farming in decentralized finance allows you to earn cryptocurrency by locking assets in DeFi protocols. Users earn interest by providing liquidity or participating in staking. Despite the high potential for returns, there are risks, including rug pulls, smart contract vulnerabilities, and price volatility.

What is the financing rate? The core principle is explained in one article.
In the cryptocurrency perpetual futures market, the funding rate is a key mechanism for maintaining market order. Simply put, it is a periodic fee transfer between long and short positions. This fee is not a commission charged by the exchange, but a direct transfer between position holders.
The financing rate can be either positive or negative. When the financing rate is positive, long traders pay fees to short traders; when the financing rate is negative, short traders pay fees to long traders. This automatic adjustment mechanism ensures that the price of perpetual futures contracts does not deviate too far from the spot market price.
Why do perpetual futures require a funding rate mechanism?
Unlike regular futures contracts that have an expiration date, perpetual futures contracts have no delivery date, allowing traders to hold positions indefinitely. This creates a problem: if left unchecked, futures prices may deviate from the spot.

IDO (Initial Decentralized Offering) is a blockchain-based fundraising mechanism that differs from traditional methods. It operates through smart contracts on decentralized exchanges, allowing direct investment from users' wallets. Key advantages include immediate liquidity and organic pricing, but investors must be aware of associated risks, including potential scams and market volatility. Careful research is essential before investing.

Information systems constantly face growing security threats. Cybercriminals attempt daily to intercept, damage, or steal critically important data transmitted through open communication channels. To combat these challenges, humanity has turned to one of the most powerful insights.

Exponential Moving Average (EMA) is a Technical Analysis tool that can quickly respond to asset price trends. Compared to ordinary Moving Averages, EMA places more weight on the latest price data. By calculating the Closing Price of a specific period and the previous EMA, traders can use EMA to assess market trends, apply crossover strategies, and combine with SMA to reduce the risk of false signals. Although EMA is sensitive and effective, it is not perfect and should be used in conjunction with other indicators to manage risk.

Decentralized Initial DEX Offerings (IDOs) are a novel fundraising method for cryptocurrency projects, allowing token sales on decentralized exchanges without central control. They utilize smart contracts for instant trades and fair pricing, but come with risks like project reliability and potential fraud. Investing requires careful analysis and understanding of potential losses.

Why has this "free pie" of Airdrop become a hotbed for scams?
If you've been in the crypto space, you've definitely heard the term "Airdrop". Normally, this is a token that project teams distribute for free to promote themselves — a seemingly great marketing strategy. But here's the problem: because some people actually profit from airdrops, scammers have also caught on to the opportunity.
In recent years, how fast has the growth of fake airdrop scams been? As long as a strange coin has appeared in your wallet, you know: the scammers have already set their sights on you.
The three major tricks of scammers

These fake websites often come from social media, email mass sending, and even through black

Quick Overview
Economic models are essential tools for understanding market operations. They break down complex economic systems into analyzable parts, helping us predict price fluctuations, market trends, and policy impacts. These models are not only applicable to traditional economic analysis but also hold significant reference value in the crypto asset market.
Why is it important to understand economic models?
Economics involves numerous interconnected factors, making it difficult to analyze the entire system directly. Economists have developed a methodology—by deconstructing and simplifying, using economic models to understand economic interactions.
The main value of economic models includes:
- Revealing causal relationships between different economic variables
- Predicting future economic trends and events based on historical data
- Assessing the potential impact of specific policy interventions
- Providing quantitative basis for business decisions and policy formulation
