The technology used to develop decentralized applications (dApps) primarily includes blockchain platforms. Blockchains are distributed ledgers that enable secure data transactions without the need for a central authority. These applications utilize smart contracts—self-executing contracts with the terms directly written into code—facilitating transactions and interactions on the network. Popular blockchain platforms for dApp development include Ethereum, Binance Smart Chain, and Polkadot. The decentralization aspect enhances trust, transparency, and security, making dApps a preferred choice for various industries looking to innovate and provide user-controlled experiences.
