Decentralized applications (dApps) are underpinned by blockchain technology, which enables the creation of secure and transparent applications that operate independently of a central authority. This technology leverages a distributed ledger to maintain data integrity and user autonomy. Blockchain’s key features, such as immutability and smart contracts, allow transactions to occur without intermediaries, reducing the risk of fraud and enhancing trust. As a result, dApps can provide more democratized access to services, fostering innovation in various sectors.
