Blockchain and Web3 Revolution

Blockchain is a distributed ledger technology that records transactions securely and transparently. It's the backbone of cryptocurrencies and decentralized applications (dApps). **How Blockchain Works**: Transactions are grouped into blocks and linked together using cryptography, ensuring data integrity and immutability. **Key Features**: - **Decentralization**: No central authority controls the system. - **Transparency**: Transactions are visible to all participants. - **Security**: Cryptographic techniques prevent tampering. Applications beyond cryptocurrencies: - **Smart Contracts**: Self-executing contracts with predefined rules. - **NFTs**: Unique digital assets representing ownership. - **Supply Chain**: Transparent tracking of goods. Web3 extends blockchain to create a decentralized internet. Key tools include Ethereum, Solidity, and frameworks like Truffle. Begin your journey by creating a simple smart contract or interacting with blockchain APIs. Platforms like Alchemy and Moralis offer free tools to experiment.
