Mastering Hyperledger Chaincode Development using GoLang

• Chaincode development using GoLang
• Application Development using Fabric Node SDK
• Use of Private Data
• Use of Instantiation & Endorsement policies
• Building support for Rich Queries & Asset History
• Building Programmatic access control with "Client Identity Library"
• Testing tools for Chaincode such as Golang Testing framework & MockStub

NOTE:

• April 2020 - Course updated to Fabric 2.1

Developers face many challenges when it comes to developing Hyperledger Fabric Chaincode.

• Lack of documentation from developer's perspective

• Need to setup the Fabric development environment

• Non-availability of development tools | standard practices

• No comprehensive guide on how to productively develop chaincode

This course is my attempt to address all of these challenges.

E.g., Student do not need to spend time on setting up dev environment from scratch - course provides "One ClickLaunch"

E.g., Course provides development utilities that will help developers to focus on learning to code

E.g., Shows step by step how to leverage various Fabric concepts to build working chaincode

E.g., Working chaincode for ALLconcepts covered in the course

E.g., Commands to be used for development purposes (wrapped in utility scripts as part of the course)

Utility Scripts

• Utility scripts are provided to achieve developer productivity; long commands on command line are difficult to follow & type

• Students may need to go through some of the utility scripts on their own

PLEASEDONOTJOINTHECOURSEif you do not like to use productivity/development scripts and rather type long command on the terminal prompt :-)

PS:

• This is a Hands on course. Please do NOTjoin if you do not have experience in coding

• Take a preview of the lectures. Please do NOTjoin if you do not understand my accent or lecture pace :-)

Course Highlights:

• Ready to use development environment setup with multiple configurations (project repository available for download)

• Hyperledger Explorer setup that may be launched by students to get a graphical view of the network

• Provides easy to use tools/scripts so that developers can focus on learning Chaincode development

• Sections start by going over the concepts. Walk through lectures show the concepts in action with REALcode

• Every section requires the student to do coding (exercises)

• ALLsections | ALMOST alllectures requires the student to do Hands On activities
