What is Web3 & Web 3.0? Is there a difference?

What is Web3?

“Web3” commonly refers to blockchain-based approaches to ownership and online services. “Web 3.0” can also refer to the Semantic Web, where structured data helps systems exchange and interpret information. The terms are sometimes used interchangeably, so context matters.

The familiar Web 1.0, Web 2.0 and Web3 labels describe overlapping approaches, rather than eras with precise starting and ending dates.

Web 1.0: Early websites were largely pages to read and navigate. The label is useful shorthand for that publishing model, although interactive services also existed.

Web 2.0: Social networks, publishing tools and online platforms made it easier to create and share content. These services remain widely used; they did not end in 2014.

Web3: Blockchain applications can let users hold transferable tokens and authorize activity through their own wallets. The degree of decentralization varies, and a token does not automatically give ownership of a company, copyright or control over a service.

Is there a difference between Web3 & Web 3.0? 

The distinction depends on how the author uses the terms.

The Semantic Web concerns structured, linked information. Blockchain-oriented Web3 focuses more on shared ledgers, tokens and wallet-based interaction. A product can use elements of both, without necessarily improving privacy or security.

What to assess in practice

Look at who can change the system, who controls access, how data is stored and which rights a token actually gives. Those details are more useful than assuming that a Web3 label establishes a better product.
