A Beginner's Guide to Blockchain Data Exploration
Navigating the world of blockchain can be overwhelming, especially for newcomers. With the recent surge in NFT-related events and WEB3 adoption, understanding tools like Etherscan—the primary Ethereum blockchain explorer—has become essential. This guide will help you decode blockchain data and leverage Etherscan's features effectively.

1. Etherscan: Capabilities and Limitations
What Etherscan Can Do:
