Web3 represents the next evolution of the internet, built on blockchain technology. Unlike Web2 (dominated by tech giants), Web3 is decentralized, giving users control over their data and digital identities. Ethereum is a key player, enabling smart contracts and decentralized applications (dApps). Web3 also includes NFTs, DeFi, and DAOs, creating a user-owned internet. Challenges remain, such as scalability and adoption, but Web3 promises a more open and fair digital economy.

Blockchain is a distributed ledger technology that records transactions across multiple computers securely. Each block contains data, a timestamp, and a link to the previous block, forming a chain. This design makes tampering nearly impossible. Blockchain is the backbone of cryptocurrencies like Bitcoin and Ethereum but has broader applications, including supply chain tracking, voting systems, and smart contracts. Its decentralized nature eliminates intermediaries, reducing costs and increasing efficiency. Transparency and immutability are key features, making blockchain revolutionary for many industries.

Over the next decade, blockchain technology is expected to evolve significantly, driving innovation across industries. Decentralized finance (DeFi) will expand, offering more secure and accessible financial services without intermediaries. Central bank digital currencies (CBDCs) will gain traction, integrating blockchain for faster, transparent transactions. Additionally, scalability improvements (e.g., layer-2 solutions, sharding) will address current speed and cost limitations. Interoperability protocols will enable seamless cross-chain transactions, fostering a connected blockchain ecosystem.
