Web3 is an exciting and innovative space with groundbreaking concepts. This article shares my perspective on Web3 and provides a roadmap for getting started with development in this domain.
Introduction to Web3
Unlike traditional Web2, Web3 applications decentralize backend services by running them on blockchain networks.
Key differences:
- Web2: Uses centralized servers (Java/Go) and databases (MySQL/Redis)
- Web3: Uses smart contracts (Solidity/Rust) running on-chain with data stored in the blockchain
Pros and Cons of Web3
Advantages:
- Tamper-resistant data (unless admin privileges exist)
- Transparent smart contract code
- Ideal for DeFi applications
Challenges:
- Transaction delays (seconds to minutes)
- Less suitable for high-frequency applications
