Blockchain project

Blockchain app / client

This folder contains the Angular web application.

Blockchain app / server

This folder contains the Spring Boot application which runs an embedded Tomcat server and connects to the HyperLedger Fabric network using the fabric-gateway-java dependency.

Blockchain smart-contract

This folder contains the smart contract developed in NodeJs using dependencies like fabric network, the project is then compiled, packaged and loaded onto a fabric environment. It takes advantage of IBM Blochain Platform VScode extension to load and manage the smart-contract onto the local fabric network.

Blockchain Wallet Migration

This folder is mainly used for migrating the wallet from the 1.4 Version to 2.x+ because the server application uses th latest fabric-java-sdk dependency which uses a new, faster way to configure a wallet to use withing the network.
