A Comprehensive Guide to Building Decentralized Applications
This comprehensive course provides a comprehensive overview of Hyperledger Fabric development, catering to both novices and seasoned developers who are interested in creating decentralized applications (DApps). The course covers the fundamental aspects of Hyperledger Fabric, including its architecture and components, and then delves into more advanced topics such as chaincode lifecycle, front-end DApp development, complete application deployment, advanced fabric concepts, and considerations for production networks. Upon completion of this course, participants will have practical experience in establishing local fabric networks, writing and deploying chaincodes, creating user-friendly DApps, and managing high-quality fabric networks.
Hylerdeger Fabric Developer Objectives
By the end of this course, participants will be able to:
Understand the Architecture: Comprehend the core components of Hyperledger Fabric and its architecture, including peers, orderers, channels, and more.
Set Up Local Networks: Implement a local fabric network using Docker compose, CLI, and SDKs.
Develop Chaincodes: Write, install, instantiate, and upgrade chaincodes using Go and shim APIs.
Manage Chaincode Lifecycle: Understand the full lifecycle of chaincode, including approval, commitment, security, and integration with CouchDB.
Build Frontend DApps: Develop decentralized applications using popular frameworks like Node.js and React, and connect them to Hyperledger Fabric.
Deploy Applications: Master end-to-end deployment of DApps with integrated REST APIs, UI development, and network monitoring.
Implement Advanced Concepts: Work with access control lists, channels, private data, hardware security modules (HSM), and decentralized identity management.
Manage Production Networks: Understand the considerations for deploying in a production environment, including high availability, monitoring, logging, and data migration.
Prerequisites
Programming Knowledge: Familiarity with programming languages like Go, Node.js, and understanding of React is beneficial.
Understanding of Blockchain: Basic understanding of blockchain technology and decentralized systems.
Software Requirements: Access to a computer with Docker, Go, Node, and other related development tools installed.
Recommended Experience: While not mandatory, previous experience with Hyperledger Fabric or other blockchain platforms would be helpful.
