Hyperledger Hands-On second edition - Smart Contracts of the Trade Network

Trade-contracts

This repository contains the various smart contracts of the Trade Network.

There are two versions represented by the folders:

• v1 - Used from chapter 4 through 8
• v2 - Used to represent the addition of a new organization, part of chapter 9.

Under the respective version folder you will find the four smart contracts:

• Trade -- folder /trade
• Shipment -- folder /shipment
• Letter of Credit -- folder /letterOfCredit
• Export License -- folder /exportLicense

To ensure that VSCode properly identify each projects as a distinct smart contract, we recommend that you import each one separately into the workspace.

Pre requisites

Code has been tested on macOS Catalina and Ubuntu 18.04.
While it should run on other platform like Windows, it does not include the convenience scripts.

Component	Version
git	latest
jq	latest
docker	19.03-ce or greater is required
docker-compose	1.25.0 or greater installed
node	12.13.1+
npm	6.12 and above
Java	JDK 11
Gradle	6.4+
make	latest
g++	11.0.0

Note: When running the full network and smart contracts, Docker on Windows or Mac requires 8GB allocated to it. You can change this from the Docker config panel (Preferences -> Advanced)

Building the Smart Contracts

A convenience shell script is provided in the root of this repository: ./makeAll.sh

This script will invoke make all within each sub-repository. This will build, run the tests and package the smart contracts.

Manual build of the Java chaincode(exportLicense/letterOfCredit):

1. Change directory (cd) into the chaincode you want to build.
2. Run gradle build
3. To test the chaincode run gradle test

Manual build of the JavaScript chaincode(shipment/trade):

1. Change directory (cd) into the REST server you want to build.
2. Run npm install
3. To test the REST server run npm test

Deploying smart contracts

The smart contracts (aka chaincode) is deployed via the trade-network project.
