Web3

web

dapp

A broad term for internet apps that use blockchains, wallets, smart contracts, and tokens for ownership or coordination.

definition

Web3 describes applications where users interact through wallets, smart contracts, and on-chain assets rather than only through accounts controlled by a central platform. The term covers many designs and is not a single protocol.

caveats

Web3 systems can still rely on centralized frontends, hosted RPC providers, admin keys, bridges, or off-chain data. Evaluating the actual trust model matters more than the label.
