Introduction

**Course Review: Decentralized Applications (Dapps) on Coursera** In the rapidly evolving world of blockchain technology, understanding how to create decentralized applications (Dapps) is becoming increasingly essential for developers and innovators. The "Decentralized Applications (Dapps)" course on Coursera, which is the third course in the Blockchain specialization, provides an in-depth exploration of Dapp design and development, offering students invaluable skills in a field that's gaining traction across various industries. ### Course Overview The course aims to equip learners with a comprehensive understanding of how to design and develop end-to-end decentralized applications. As you navigate through the modules, you will gain hands-on experience working with tools such as Truffle IDE, smart contracts, a simple web client, and the MetaMask client. The curriculum focuses on the architecture of Dapps, highlighting both the front-end client interface and the underlying blockchain and smart contracts. ### Syllabus Breakdown #### 1. Decentralized Applications (Dapps) The course begins with an essential foundation — understanding the blockchain server architecture. In this module, learners will receive guidance on how to install a blockchain server and create a peer-to-peer network of nodes. By deploying the Dapp on a local test network before taking it live, students will learn the critical processes involved in building a reliable Dapp. #### 2. Truffle Development Truffle is a popular development framework for Ethereum that simplifies Dapp development. This module delves into the user-friendly environment that Truffle provides. It covers essential commands such as `develop`, `init`, `compile`, `migrate`, and `test`. By the end of this section, students will have a clear grasp of the entire development and testing process required to successfully build a complete Dapp. #### 3. Design Improvements The course highlights best practices that are unique to smart contracts and Dapps. In this module, students will discover various design improvements that can help in enhancing the usability and security of their Dapps, ensuring that their applications are not only functional but also adhere to industry standards. #### 4. Application Models & Standards The final module discusses important Ethereum Improvement Proposals (EIPs) and the ERC (Ethereum Request for Comment) process, which are pivotal for keeping the Ethereum blockchain updated. Students will learn about ERC 20 for token-based Dapps and ERC 721 for non-fungible tokens (NFTs), providing them with an understanding of the different application models used in the ecosystem. ### Why You Should Take This Course 1. **Hands-On Learning**: The course emphasizes practical skills, allowing students to gain experience with real-world tools and technologies that are foundational to Dapp development. 2. **Industry Relevance**: With the increasing adoption of blockchain technologies across sectors, having the ability to create Dapps provides a competitive edge in the job market. 3. **Expert Instruction**: The course is taught by knowledgeable instructors who bring their expertise and insights from the blockchain industry, ensuring that learners are receiving high-quality education. 4. **Comprehensive Curriculum**: Covering everything from the basics of Dapp architecture to advanced best practices and standards, the course provides a well-rounded education that suits both beginners and experienced developers looking to expand their skillset. ### Conclusion The “Decentralized Applications (Dapps)” course on Coursera is an outstanding resource for anyone interested in diving into the world of blockchain and decentralized technology. It offers a structured learning path that equips participants with the necessary skills to design, develop, and enhance Dapps effectively. With practical exercises, valuable insights, and contemporary curriculum, this course is highly recommended for developers, tech enthusiasts, and anyone looking to future-proof their career in the tech landscape. Whether you're a novice seeking to understand Dapps or a seasoned developer wanting to enhance your blockchain knowledge, enrolling in this course is a smart investment in your professional development.

Syllabus

Decentralized Applications (Dapps)

We will explore the notion of the blockchain server as the foundation for a Decentralized Application. We will demonstrate how to install the blockchain server and establish a peer-to-peer network of nodes. It is a common practice to develop and test a Dapp on a local test network before deploying it on a public network.

We'll explore the user-friendly environment that Truffle provides for developing and testing a Dapp. We'll explore further the truffle commands such as: develop, init, compile, migrate, test - all with truffle in front of them and with any parameters. This module will illustrate the steps needed in developing and testing a complete Dapp.

In this module, we will discuss a few of the many best practices exclusive to smart contracts and Dapps that will improve your basic Dapp design.

We will discuss Ethereum Improvement Proposal and the ERC process that are essential for keeping Ethereum blockchain updated. We will also explore the standard ERC 20 for token Dapps and ERC 721 for non-fungible tokens.
