Web3 represents a vision of a decentralized internet built on blockchain technology. As CTO of Softechinfra, I've explored Web3 technologies and their applications. Understanding Web3 is increasingly important for developers and businesses alike.
What is Web3?
Web3 refers to the third generation of the internet:
Web1 (1990s-2000s): Read-only, static websites Web2 (2000s-present): Read-write, user-generated content, platforms Web3 (emerging): Read-write-own, decentralized, user-controlled
Core Principles
Key Technologies
Blockchain
- The foundation of Web3:
- Distributed ledger
- Immutable records
- Consensus mechanisms
- Smart contracts
Smart Contracts
- Self-executing code on blockchain:
- Automate agreements
- No intermediaries
- Transparent execution
- Immutable once deployed
Decentralized Applications (dApps)
- Applications built on blockchain:
- Frontend: Traditional web tech
- Backend: Smart contracts
- Storage: IPFS, Arweave
- Identity: Wallet-based
