DApps are decentralized applications built on top of a blockchain network to leverage its computing resources, security, and consensus properties of blockchain. Unlike traditional centralized applications where data and control reside with a central authority or server, DApps utilize the distributed nature of blockchains for enhanced security and transparency. DApps typically interact with the blockchain through smart contracts to access data or perform operations securely without relying on intermediaries. They often have user interfaces similar to traditional web or mobile applications but connect directly to the blockchain network instead of relying solely on centralized servers. While some DApps may rely heavily on one or more specific smart contracts for their core functionalities (e.g., token exchanges), others may use multiple interconnected smart contracts working together to achieve complex workflows within the application ecosystem.
