1. The "Evolution" of the Internet: From Library to "My Domain, My Rules"

Imagine if the Internet were a huge library, then:

Web1.0 (1990s): The library is filled with books, but you can only passively flip through them, not even doodle.

Web2.0 (2000s to present): Readers begin to write reviews and stick notes on books, but the library administrators (giants like Google, Meta, etc.) hold all the copyrights and distribution rights of these notes. For example, the photos you post on social media theoretically belong to you, but the platform can monetize them and even delete your account.

Web3.0 aims to break this "centralized hegemony" — turning the library into a "community-built and shared space," where everyone is not only a reader but also an author, and a master of "digital assets."

2. The "Magic Tool" of Web3: How Does Blockchain Make Data "Come Alive"?

Blockchain, like a globally shared public ledger, records every transaction and piece of data. Its core features:

Decentralization: Data is not stored on a company's server but is replicated across thousands of computers worldwide, making it undeletable.

Immutable: Once recorded on the blockchain, it's like being glued with 502 adhesive, unchangeable unless agreed upon by a majority of nodes.

Transparency: Everyone can see the ledger's contents, though account identities can remain anonymous (e.g., using a public key address).

Smart contracts are the "vending machines" on the blockchain:

You input conditions (e.g., "If A transfers 100 yuan to B, automatically trigger a reward mechanism"), and the system executes automatically, without human verification.

For example, on DeFi lending platforms, users can borrow money by mortgaging cryptocurrencies, with interest calculated automatically by algorithms, eliminating the need for banks.

3. How Web3 Empowers Ordinary People to "Turn the Tables"?

1. Data ownership returns to users

On Web3 social platforms, the copyright and earnings of your posts and videos belong to you. If the platform shuts down, your digital assets won't vanish into thin air. It's like uploading photos to your digital safe rather than a company's server.

2. Using NFTs to prove "you are you"

NFTs (Non-Fungible Tokens) are the "unique certificates" of the digital world. For example:

Purchasing a CryptoPunk pixel avatar means it forever belongs to you, and you continue to earn a share when it's resold.

In the metaverse, your virtual real estate and clothing can be proven with NFTs, ending the era of "platforms can shut you down anytime."

3. Join a DAO, a "company without bosses"

DAOs (Decentralized Autonomous Organizations) are like cooperatives formed by like-minded "digital nomads":

For instance, in the Gitcoin community, developers voluntarily collaborate on open-source projects, with profits distributed based on contribution.

Major decisions are made by voting, with each person having an equal vote, completely ending "capital monopolies."

4. The "Future Battlefield" of Web3: What Areas Are Being Transformed?

Finance: DeFi eliminates the need for intermediaries in lending and trading, accessible 24/7 globally.

Art: Artists sell their works directly through NFTs, bypassing gallery commissions.

Games: Your game equipment is NFT, allowing cross-platform trading, even "laying eggs to produce small equipment."

Identity: DID (Decentralized Identity) allows you to log into all Web3 applications with one wallet, with privacy information encrypted and stored.
