Decentralized Application (DApp) Development from Coursera

The course aims to provide a thorough understanding of the core principles and characteristics of decentralized applications (DApps). Participants will learn about the benefits and challenges of DApp development, including decentralization, immutability, and user empowerment.

● Participants will acquire the necessary skills to develop front-end interfaces for DApps. They will learn modern web development technologies such as HTML, CSS, and JavaScript frameworks (e.g., React, Angular) to create engaging and user-friendly interfaces that interact with the underlying blockchain.

● The course will cover the integration of smart contracts with DApps. Participants will learn how to interact with smart contracts from the front-end using web3.js or similar libraries, enabling DApps to read from and write to the blockchain, execute transactions, and update contract states.

● Participants will gain insights into designing DApp architecture and optimizing user experience. They will learn best practices for structuring DApps, handling data flows between the front-end and smart contracts, and implementing intuitive user interfaces that seamlessly interact with the blockchain.

● The course will cover essential aspects of testing, deploying, and maintaining DApps. Participants will learn how to write comprehensive tests for their DApp's smart contracts and front-end components, deploy DApps to testnets or the mainnet, and ensure ongoing maintenance and updates to keep their DApps functional and secure.
