DApps, or decentralized applications, are software applications that run on a blockchain or a peer-to-peer network, rather than being hosted on a single centralized server. This structure enhances security and reduces the risk of control by a single entity.DApps utilize smart contracts, which are self-executing contracts with the terms directly written into code. These contracts automatically enforce and execute agreements, allowing DApps to function without relying on intermediaries.Users interact with DApps through web browsers or mobile applications, often using digital wallets to manage identity and transactions. This setup promotes transparency and fosters trust among users, as all activities are recorded on the blockchain, making it difficult to alter or manipulate data.DApps can serve various purposes, including finance (DeFi), gaming, social networking, and governance. Their decentralized nature enables global accessibility, empowering users to engage without geographical or institutional barriers, while also potentially lowering costs and increasing efficiency.
