Glossary: Web2

What is Web2?

Web2 is the current era of the internet, defined by centralized platforms that host user-generated content, own user data, and monetize attention through advertising and subscriptions.

Web2 Explained

Remember when the internet was just static pages you could only read? That was Web1. Web2 is what we have now, and it changed everything by letting regular people create content, not just consume it.

You post on TikTok, write reviews on Google, message friends on WhatsApp. That is all Web2. The catch is that every platform you use to do that owns everything you put into it. Your followers, your data, your content history. All sitting on their servers, under their rules.

Web2 made the internet social and interactive. The tradeoff is that a handful of companies ended up owning most of it.

What Web2 Means For

Examples

1. A creator builds an audience of 500,000 followers on a Web2 platform, then loses access to all of them when the platform changes its algorithm or bans their account.

2. A Web2 SaaS company stores all user data on its own servers, giving it full control over what it collects, sells, or deletes.

3. An advertiser pays a Web2 platform to reach a specific audience segment, with the platform acting as the gatekeeper between the brand and the user.

4. A user tries to move their content library from one Web2 platform to a competitor and finds there is no easy way to export or transfer it.

FAQs

What does the term Web2 describe?

Web2 is a broad label for interactive internet services built around user accounts, hosted applications, and platform-operated infrastructure. It is descriptive rather than a formal technical standard, and services vary in how they handle data and control.

What are examples of Web2 services?

Social networks, video-sharing sites, online marketplaces, and cloud-hosted productivity apps are commonly described as Web2 services. The label describes a broad operating model, not a precise technical category.

How is Web2 commonly contrasted with blockchain-based apps?

Web2 services generally rely on platform-operated accounts and infrastructure. Blockchain-based apps can incorporate public ledgers, wallets, tokens, or smart contracts, but may still rely on centralized hosting and accounts. These labels describe broad patterns rather than fixed categories.

Will blockchain-based apps replace Web2 services?

There is no basis to expect one model to replace the other entirely. Many services combine conventional hosting and accounts with selected blockchain components where those components serve a specific purpose.

Why do blockchain projects use conventional web infrastructure?

Blockchains do not replace every part of an app. Teams often use conventional hosting, databases, identity services, and frontends alongside smart contracts to support interfaces, fast queries, and operations.
