The technology that provides the framework for decentralized apps (dApps) is known as blockchain. Blockchain technology enables the creation of applications that operate without a central authority, relying on a distributed ledger to maintain data integrity and security. Smart contracts, often built on blockchain platforms, automate processes without intermediary intervention. dApps leverage this decentralization to enhance transparency, security, and resilience against failures and fraud. As such, blockchain serves as a foundational technology for various industries, including finance, supply chain management, and digital identities.
