1. Web3
1. What is web3?
When the Internet was just emerging in the 1990s, we could only view the news published by the central node on the network, and users only passively accepted it. This era, we call it web1.0.
After the millennium, Internet technology has entered the stage of being readable and writable. Users can publish photos, texts, and videos. This is the legendary web2.
Web 2.0 has brought social interconnection and generated huge value. However, as a number of Internet companies were born and grew into giants, data began to be "hidden" by the giants in their own platforms. The Web was fragmented and gradually violated the original vision.
Facing the dilemma of network monopoly, web3 came into being. Web3 is not a network monopolized by one large technology company, but a decentralized network, created, operated and owned by users.
Web 3.0 emphasizes on the basis of blockchain technology, giving control to users for the first time, and the centralized platform is replaced by distributed and decentralized blockchain services.
Personal understanding:
Web 3.0 is not an either-or, gradually replacing relationship with Web 2.0. The two are more like parallel worlds that coexist, and they also need to be connected.
2. The dapp architecture of web3
Traditional Internet products generally adopt the classic C/S (Client/Server) architecture.
The centralized application in web2.0 is completely different from the application system in web3.
Those services on the server side that need to be non-tamperable, open and transparent, and confirmed are put on the public chain. The Server side evolved into Server/Mainnet.
Coupled with the Web UI interface for ordinary users, the general architecture of encryption products has become C/S/M (Client/Server/Mainnet).
Encrypted product architecture = smart contract + business server + front-end UI
