Stable coins maintain price stability by anchoring fiat currencies such as the US dollar, which are mainly divided into three categories: 1. Fiat currency collateralization types such as USDT and USDC; 2. Cryptocurrency collateralization types such as DAI; 3. Algorithm types have higher risks. Mainstream stablecoins include USDT with the highest market value and the best liquidity. USDC is known for its compliance and transparency. DAI relies on the decentralized mechanism. TUSD adopts on-chain real-time audit. BUSD is gradually withdrawing from the market due to supervision. USDP is known for its high compliance and security. Both are widely circulated on mainstream exchanges.

The currency circle seems to have a low threshold, but in fact it hides a lot of terms and complex logic. Many novices "rush into the market" in confusion and end up losing money. This article will give a comprehensive explanation of common terms in the currency circle, the operating logic of real money makers, and practical risk control strategies to help readers clarify their ideas and reduce investment risks.

MySQL supports transaction processing, and uses the InnoDB storage engine to ensure data consistency and integrity. 1. Transactions are a set of SQL operations, either all succeed or all fail to roll back; 2. ACID attributes include atomicity, consistency, isolation and persistence; 3. The statements that manually control transactions are STARTTRANSACTION, COMMIT and ROLLBACK; 4. The four isolation levels include read not committed, read submitted, repeatable read and serialization; 5. Use transactions correctly to avoid long-term operation, turn off automatic commits, and reasonably handle locks and exceptions. Through these mechanisms, MySQL can achieve high reliability and concurrent control.

Character set and sorting rules issues are common when cross-platform migration or multi-person development, resulting in garbled code or inconsistent query. There are three core solutions: First, check and unify the character set of database, table, and fields to utf8mb4, view through SHOWCREATEDATABASE/TABLE, and modify it with ALTER statement; second, specify the utf8mb4 character set when the client connects, and set it in connection parameters or execute SETNAMES; third, select the sorting rules reasonably, and recommend using utf8mb4_unicode_ci to ensure the accuracy of comparison and sorting, and specify or modify it through ALTER when building the library and table.

Recently, the discussion in the digital asset field has remained hot. Dogecoin DOGE, as one of the most popular focus, has become a question that many people have explored. Where does it "settling down"? What is the relationship with the current leading trading platform, Binance?

Whether you operate on mainstream trading platforms such as Binance Binance, Ouyi OKX, Huobi, or Gate.io Sesame Open Door, they all form the core of your trading strategy.

The core difference between USDC, DAI and TUSD lies in the issuance mechanism, collateral assets and risk characteristics. 1. USDC is a centralized stablecoin issued by Circle and is collateralized by cash and short-term treasury bonds. Its advantages are compliance and transparent, strong liquidity, and high stability, but there is a risk of centralized review and single point failure; 2. DAI is a decentralized stablecoin, generated through the MakerDAO protocol, and the collateral is a crypto asset. It has the advantages of anti-censorship, transparency on chain, and permission-free, but it also faces systemic risks, dependence on centralized assets and complexity issues; 3. TUSD is a centralized stablecoin, emphasizing real-time on-chain reserve proof, providing higher frequency transparency verification, but has a small market share and weak liquidity. The three are collateral types and decentralization
