Building Your First Ethereum Dapp Practice Exam

Building Your First Ethereum Dapp Practice Exam

Building your first Ethereum DApp (Decentralized Application) means creating an application that runs on the Ethereum blockchain instead of a traditional centralized server. Unlike normal apps where data is stored in one company’s database, DApps use smart contracts on Ethereum to ensure transparency, security, and decentralization. This allows users to interact directly with each other without needing a middleman, such as a bank or big corporation.
For example, you could build a DApp for secure payments, voting, or digital collectibles. With Ethereum, these apps are trustless, meaning the rules are enforced by code instead of people. Learning to build your first Ethereum DApp helps you understand how blockchain works and gives you hands-on experience in creating the technology behind cryptocurrencies and Web3 innovations.
