The idea is usually framed as a progression. Web1 was the early read-only internet of static pages you could only look at. Web2 is today's interactive internet, where you create and share content but a small number of large companies own the platforms, the accounts and the data. Web3 proposes a next step in which ownership and control shift back toward users through blockchains, self-custody wallets and tokens, so your identity and assets belong to you rather than sitting as entries in a company's private database.
In practice, Web3 today mostly refers to the growing ecosystem of dApps, DeFi, NFTs and self-custody wallets. Instead of logging in with a platform account, you connect a wallet you control and interact directly. Supporters argue this reduces dependence on gatekeepers and resistance to censorship; sceptics counter that much of it remains early, clunky, and sometimes more centralised in reality than the marketing suggests, with real risks attached for ordinary users.
It is best understood as an evolving aspiration rather than a finished product. The honest view is that Web3 captures a genuine and interesting set of ideas about ownership and openness, while a great deal of what it promises is still very much a work in progress. Crypto House covers it as a concept to understand critically, not as a guarantee of what the internet will become.
Key takeaways
- Web3 describes a blockchain-based internet where users own their data and assets rather than platforms owning them.
- It is often contrasted with Web2, today's platform-dominated internet, as a shift back toward user control.
- In practice it refers to dApps, DeFi, NFTs and self-custody wallets, and it remains early and uneven.
Web3 — preguntas frecuentes
How does Web3 differ from Web2?
Web2 is today's internet, where large platforms own the accounts, data and content you create. Web3 envisions blockchain-based services where you hold your own identity and assets through a wallet you control, rather than through a platform account.
Is Web3 just another word for crypto?
Not quite. Crypto refers to the assets and networks themselves, while Web3 is the broader idea of using them to build a more user-owned internet. Web3 relies on crypto, but it is a vision and a direction rather than a single technology.
