Blockchain in dApps (decentralized applications) ensures transparency, security, and decentralization. It operates on a distributed ledger where transactions are recorded on-chain via smart contracts. Unlike traditional apps, dApps run on blockchain networks like Ethereum, enabling trustless interactions. A dApp development company make these applications with features like token integration, decentralized storage, and automated processes. By using blockchain, dApps eliminate intermediaries, enhancing efficiency and security for industries like finance, gaming, and supply chain management.
