HyperledgerProjects

The repository contains a POC for using different Hyperledger Fabric Components

Folder Strucutre

• use case : sample use case for an Art Forgery/Artifact Transfer Network
• artprovenance : contains the HLF related network configuration files
• decentralization : contains answers to decentralization section
• guides: containes steps to execute run the network & use of configtxlator to extend the network

The master & client_app branches has the complete working poc

Covering Kafka/Nodejs client SDK/Chain code

Network topology

• 3 Orderers
• 3 Zookeepers
• 4 Kafka brokers

The [guides][guides/] section covers:

1. Artifact Transfer test Script
2. How to generate client app ceertificates
3. How to use CONFIGTXLATOR to ass a new org

A working chain code example is available [here][/artprovenance/artifact/chaincode/artifact_transfer]

To setup for firt time use ./setup.sh or excute the commands manually according to your envirnoment.

The [runTestScript.sh][/artprovenance/runTestScript] is semi-automated test script for the artifact transfer chaincode

Storing the keys

cp -a .hfc-key-store/ ~/.hfc-key-store

Client App Test script

the follwoing will trigger create function
