English Web3 Basics
What is Web3, and how does it differ from Web2?
Understand Web3 through control of accounts, assets and application rules.
The short answer
Web3 describes applications that emphasize user control of digital assets, identity and interaction rules, often using blockchains and smart contracts. It is not one product, and it does not mean every website needs a token.
Start with the product problem
A conventional membership site can store accounts, orders and permissions in a database. Consider an on-chain design when independent asset control, shared verification or publicly executed rules matter. This is a planning recommendation, not a strict definition of Web3.
Web2 and Web3 can work together
A product can keep its website, support desk and business dashboard while adding wallets and contracts. Assess hosting, administrative powers and contract rules separately; a wallet button alone does not tell you how the product is governed.
Define three boundaries in the specification
Specify what must be on-chain, which actions users must confirm and which powers remain with the project team. Describe one complete user journey before choosing networks and tools.
A project checklist
- Identify what needs on-chain verification: assets, permissions or records.
- Map responsibilities across users, the dashboard and contracts.
- Validate the core journey before discussing tokens or growth mechanics.
Common questions
Does a Web3 project need its own token?
No. A token should follow a specific product mechanism. Wallet login, credentials or verification do not by themselves justify creating one.
Can an existing website add Web3 features?
Start by assessing how wallets and contract interactions fit the existing account system, then define the integration scope.
