📖 Reading: The Promise and Reality of Web3

Web3 represents a vision of a decentralized internet where users control their own data and digital assets. Built on blockchain technology, Web3 aims to eliminate centralized intermediaries, giving power back to individuals through cryptographic protocols and distributed systems. While blockchain first gained attention through Bitcoin, its applications extend far beyond cryptocurrency.

Smart contracts—self-executing code on the blockchain—enable trustless transactions and decentralized applications (dApps). These applications run on peer-to-peer networks rather than centralized servers, theoretically offering greater transparency, security, and user control. Non-fungible tokens (NFTs) represent unique digital assets, while decentralized finance (DeFi) reimagines traditional financial services without banks.

Critics argue that Web3 faces significant challenges: high energy consumption, scalability issues, regulatory uncertainty, and a steep learning curve for mainstream adoption. Many implementations have been criticized as solutions looking for problems. However, proponents believe that decentralization will fundamentally reshape how we interact online, creating more equitable and user-centric digital ecosystems.
