Blockchain Development on Hyperledger Fabric using Composer

via Udemy

Overview

Learn to develop Network Applications on Hyperledger Fabric & Composer Technology

What you'll learn:
  • Develop Hyperledger Blockchain Applications using Composer Framework
  • Model the Blockchain Applications using Composer modeling language
  • Evaluate if a business application will benefit by adoption of Distributed Ledger Technology
  • Develop front end (Client) applications using Composer API
  • Leverage Composer REST Server to design a web based Blockchain solution
  • Describe the various components of Hyperledger Fabric Technology (Peers, Orderer, MSP, CA ...)
  • Design Hyperledger Fabric Composer Business Network Application (NOT the infrastructure)

PS: Please READall the pointsbefore proceeding


***Composer - DEPRECATED- it is NOmore supported for Fabric updates***


But it is still a GREATway to learn Fabric Blockchain fundamentals & for carrying out POC. For production grade apps It is suggested that you take a look at my course "Mastering Chaincode Development using GoLang ...."

  1. Please do NOTjoin the course if you are NOT comfortable with coding

  2. Focus of the course is Composer based applicationdevelopment. Course will NOTteach you how to use ALL the various utilities/tools for hypereldger infrastructure component setup.

  3. Course is NOTfor Operators or Infrastructure engineers *but* you are welcome to try as it would help you in building a strong foundational knowledge. Take a look at my other Fabric courses if you are an Operations person.

  4. You MUSThave a basic understanding of Blockchain technology. Do take a preview before joining.

  5. This course willNOTteach you Javascript or any Javascript framework to develop UI

  6. You MUSTbe comfortable in installing software & tools on your machine. Course requires many tools to be installed.

  7. Please read thePre-Requisitesbefore signing up

  8. Try out the lectures in preview - if you have difficulty understanding the lectures/accent....I request youNOT tojoin

If you are still with me lets continue :-)

Background

Demand for Blockchain technologists is going up as multiple enterprises (&startups) are looking to achieve efficiency or/and create new business models enabled by the Blockchain technologies. Bitcoin & Ethereum have proven to the world that Blockchain technologies can change the way we do business. The challenge with these technologies is that they were both built ground up for public domain applications and are not always suitable for building an enterprise grade application. Hyperldger project, a Linux foundation initiative is driven by theindustry leaders to build Blockchain technology(s) that would provide a platform for creating Enterprise Blockchain Applications.

Business |Enterprise Blockchain Applications

The obvious question you may have at this point is, what do I mean by "Enterprise Blockchain Applications". The idea is that Blockchain technology for Business (or enterprise)would need to have certain characteristics that do not necessarily apply to the public domain Blockchain technology such as Ethereum. Characteristics that aredesired

  • Permissioning,

  • Network support | operation

  • Smart contract management

  • Control on howtransactions arevalidated

  • Trust management

  • Scaling, Performance, Throughput

  • ...

Hyperledger Fabric | Composer Framework

Hyperledger Fabric is a "Distributed Ledger Technology" a.k.a. Blockchain technology that has been builtground up with the needs of the "Business Blockchain Applications" in mind. Composer is adevelopmentframework that accelerates the development of Business Blockchain applications of Fabric platform.

This course will teach you how to develop Fabtric Blockchain Application using Composer.

Course Approach?

This course takes the approach of “Learnby doing”. Students are encouraged to try out all aspects of the technologies on their own aftereach lecture. Almost allof the concepts discussed in thelectures are shown in action by way code samples etc. The demo code used in the lectures is available for download from GitHub so that students can change the code to try out new things.

Multiple quizzes in each section will validate student’s knowledge. Coding exercises will help them understand the concepts better & gain confidence.

Course Outline

#1 Build a foundation - coversBlockchain concepts +Hyperledger project-fabric-composer

#2 Introduction to Hyperledger Fabric &Composer Technology

#3 Setting up the development tools - (Docker, NodeJS,Fabric, Composer tools ...)

#4 Fabric under the hood - student will learn how the Fabric technology works

#5 Learn to use the Composer tools (Modeling, Yo generators, RESTServer, CLI, Playground ...)

#6 ACMEAirline Blockchain Application : We will develop a Network application for this fictitious Airline

  • Business network modelling

  • Smart contracts development

  • Transaction processors - coding in Javascript

  • Client side code - in Javascript

  • Participant management

#7 Composer SDK/API

#8 Transaction flow in Fabric - unravel some of the mysteries :)

How can this course help you?

Many enterprises today are embarking on building Blockhain applications for their business domain. At this time the focus is on trying out the technologies by way of Proof of Concepts | Pilots. This course can put you on track to build the pilots/PoC in a very short period of time (~3 weeks)

Information of Hyperledger frabric (& Composer) is available online and freely.....so why take this course?

  • There are known challenges :The author of this course have gone through the development cycle many times and have taken care of describing the known challenges (& pitfalls)and solutions so, students won't struggle....& spend time on learning rather than searching for solutions on google :)

  • Learning curve is steep : Although information is available it would take new students considerable amount of time to digest &understand. The course has been designed to accelerate the learning process without overwhelming the students with too many details.

  • Coding guides | experience is limited : For every topic discussed in the course, there is a sample code. Seeing things in action and trying out the code will accelerate the learning

  • Time to market:Taking this course will prepare the student for the challenge - delivery of a working Fabric PoC/Pilot in 3 weeks is the goal :) [Assuming student spends 2 Hour/Day]
