Blockchain browser is a must-have on-chain query tool for Web3 users. 1. It serves as a "search engine" in the decentralized world, allowing users to openly and transparently verify all records on the blockchain; 2. The core functions include querying transaction details, viewing account information, exploring block data and tracking smart contracts; 3. When tracking transactions, you need to obtain the transaction hash, select the browser corresponding to the public chain, and enter the hash to view the status, address, amount and fee details; 4. Confirm whether the transaction is successful through the browser is a key step to ensure the security of digital assets. Proficient use can help users better understand and participate in the blockchain ecosystem, thereby operating more safely and stably in the decentralized world.

Blockchain confirmation time refers to the time it takes for a transaction to be broadcasted to be packaged by a block and written to the chain. The confirmation speeds of different chains vary. 1. Bitcoin produces blocks on average in 10 minutes, and it is recommended to confirm 6 times to ensure security; 2. Ethereum produces blocks in about 12 seconds, and 1-3 times can be confirmed, and most transactions are completed within 1 minute; 3. The BSC chain block time is about 3 seconds, suitable for high-frequency trading; 4. The TRON tide block time is 1-3 seconds, suitable for real-time transfer; 5. The Polygon block time is about 2 seconds, with low fees, and is widely used in DeFi and NFT. Trading hash (TxID) is required for query and confirmation status. Recommended platforms include: 1. Ouyi OKX, which supports multi-chain transaction query; 2. Binance, suitable for BSC chain; 3. Huobi HT

Public keys are used to receive assets and identity identification, private keys are used to sign and control assets. The two are based on asymmetric encryption technologies such as ECDSA. Private keys can be derived from public keys but vice versa. mainstream platforms such as Ouyi OKX adopts multiple signatures and cold storage, Binance uses hardware isolation and layered permissions, Huobi HTX implements hot and cold separation and whitelisting mechanisms, and Gate.io gate combines multiple signatures and distributed storage; public keys and private keys are used in blockchain for identity authentication, asset control and decentralized login; key security management suggestions include offline backup, anti-phishing, enabling multi-factor authentication and using multi-signature or MPC; among different management methods, single keys are at high risk, multiple signatures are suitable for teams, and hardware equipment is highly secure but costly.

High-frequency trading is one of the most technologically-rich and capital-intensive areas in the virtual currency market.
