HyperLedger-Fabric-App

Created a MarketPlace Use case using IBM Hyperledger Fabric

Inspiration:

• CraigList.
• The Distibuted Ledger Technology to have single Ledger distributed over the various nodes.This single ledger helps in deriving the history of the commodity and its flow between the different ownerships.
• Similar Use case implemented in Ethereum Platform

What it does:

• The purpose of the DApp is to buy and sell commodities between the different accounts.
• Also the event monitoring process in order to maintain the single ledger for transactions.

Challenges:

• Cloud setup and its Integration
• Security certification problems using local instances and docker images
• Docker Images management
• Angular Js Integration

Implementation:

• Docker - Run the Hyper Ledger Fabric Peer
• Hyperledger Composer - To define the Business Network definitions (Model files, Logic Javascript, Access Control List)
• Composer Rest Server - To create the REST API Interface to the Hyperledger Application
• Angular Front End - To Interact with expose REST API.

Build With:

• Hyperledger Fabric, Composer, Docker, Node.js, Angular.js, Docker, REST, Shell script, Bluemix.
