What is a dApp?
A decentralised application, or dApp, runs on a blockchain network instead of a company’s central servers. Its core logic lives in smart contracts that anyone can inspect.
How it works
Users typically connect to a dApp with a crypto wallet rather than a username and password. Because the code is open and runs on a shared network, no single operator can quietly change the rules.
