Introduction to web3: Web3 is a widely used term to describe the next generation of the Internet, emphasizing the concepts of decentralization, openness, and user empowerment. Here's a brief introduction to Web3 for someone unfamiliar with the concept: 1、Web2 vs. Web3: Web2 (the current Internet) is dominated by centralized platforms such as Google, Facebook, and Amazon, where user data and power are largely controlled by these platforms. Web3, on the other hand, strives for decentralization, aiming to create an Internet where users have more control, enabling them to directly participate and control their data through technologies like blockchain. 2、Decentralized Technologies: Blockchain is a core technology of Web3, serving as a distributed ledger to ensure transparency and security of data without the need for centralized verification. Smart contracts are self-executing contracts on the blockchain, automating transactions without the need for intermediaries, thus enhancing efficiency and reliability. 3、Digital Assets and Cryptocurrencies: In Web3, digital assets are issued and managed through blockchain technology, including cryptocurrencies (such as Bitcoin, Ethereum) and non-fungible tokens (NFTs). These digital assets can be utilized in decentralized applications (DApps), which are applications built on the blockchain and not controlled by a single entity. 4、User Privacy and Data Ownership: Web3 emphasizes user ownership of data, achieved through decentralized identity verification and storage, allowing users better control over their personal information. 5、Open Standards and Interoperability: Web3 aims to promote open standards and protocols to ensure better interoperability among different decentralized applications and platforms. In summary, Web3 aims to create a more open, decentralized, and user-friendly Internet, allowing users to directly participate and benefit from the digital economy.
