A key feature of decentralized applications (dApps) is their reliance on blockchain technology, which allows them to operate without a central authority or intermediary. This decentralization promotes transparency, as the underlying code is usually open-source and accessible to users. dApps leverage smart contracts—self-executing contracts with the terms directly written into the code—enabling automated execution of processes without manual intervention. This reduces the risk of fraud and increases security, as data is distributed across a network rather than being stored in a single location. dApps are utilized in various fields, including finance, gaming, and supply chain management.
