This refers to the creation of decentralized applications (dApps) that run on blockchain networks. These applications leverage blockchain technology to operate without a central authority, offering transparency, security, and immutability. In dApps development, developers use languages like Solidity to write smart contracts, ensuring automated and trustless execution of agreements. This process involves designing, coding, testing, and deploying decentralized applications to provide innovative solutions across various industries, from finance and supply chain to gaming and healthcare.
