Web2 gave users convenient platforms but left accounts, data, and assets inside company databases. Web3 tries to make some of those assets portable through wallets and chains.

Mechanics

How to reason about Web2 vs Web3

In Web2, login usually proves access to a platform account.

In Web3, wallet control can prove ownership across applications.

The useful shift is portability, not adding tokens to every product.

Web2 platforms own your data and assets
Web3 aims to give ownership back to users via blockchains
Ownership is the defining difference, not the technology

Example

Web2 vs Web3, applied

A Web2 game item may disappear if the platform shuts down. A Web3 item can be held in a wallet and potentially used or traded elsewhere if the ecosystem supports it.

RememberDecision rule: Ask what the user can actually do with the asset outside the original platform.

Common mistakes

The usual Web2 vs Web3 trap

Web3 ownership is often overstated. A token may prove ownership, but images, rights, utility, and servers can still be off-chain.
