A dApp protocol, or decentralized application protocol, refers to a set of rules and standards that enable the development and operation of decentralized applications. These applications run on a blockchain network, allowing them to operate independently of a central authority.Protocols typically define how data is shared, how transactions are processed, and how users interact with the application. They ensure security, transparency, and trust among participants by utilizing smart contracts, which are self-executing contracts with the terms directly written into code.Developers can build various dApps on these protocols to serve diverse purposes, such as finance, gaming, and social networking. Popular examples include Ethereum, which supports numerous dApps, and protocols like TRON and Polkadot, each offering unique features and frameworks for developers.By leveraging dApp protocols, users can engage with applications without relying on intermediaries, thus promoting a more open and efficient ecosystem.
