Introduction to Blockchain Explorers
A blockchain explorer is a specialized tool that allows users to browse and query transactional data on a blockchain network. Unlike traditional web browsers, these explorers focus exclusively on retrieving blockchain-specific information. Mastering this tool is essential for anyone navigating the WEB3 space.
Key Features:
- Provides real-time access to transaction histories, wallet balances, and block details
- Each blockchain has its dedicated explorer (e.g., Bitcoin explorers only work for BTC data)
- Serves as a transparent ledger verification system
