What is Web3?

The vision that blockchains and smart contracts form the next era of the web — permissionless and decentralized, where users own their data and the protocols instead of centralized companies.

Framed against Web1 (read-only but open) and Web2 (interactive but company-controlled), Web3's core promise is ownership: decentralized networks run the logic transparently and participants can hold a stake in what they use.
