TCCSCI Demo System

A Docker-based demo for SCIP and T-SCIP using a Hyplerdeger Fabric instance, a private Ethereuem instance, a SCIP Gateway, and a client application.

Prerequisites

• Fulfill the Hyperledger Fabric installation requirements.
• Git
• The following ports must be free:
  • 7050 - 7051
  • 7053 - 7054
  • 7545
  • 8080
  • 8054
  • 9054
  • 9443 - 9444
  • 17054
  • 18054
  • 19054
• Ensure to replace the IP address provided in /scip-gateway/connectionProfiles with the external IP address of the host machine (found using ipconfig for example).

Usage

StartAll.sh

The script deploys and starts the demo scenario. Invoke this script as follows:

./StartAll.sh [no-cache]

Specifically, it does the following:

• Pulls the official fabric-samples.
• Starts the official fabric test-network.
• Deploys the Fabric 2PC4BC Resource Manager Smart Contract along with a sample smart contract to a channel on fabric.
• Deploys a ganache network.
• Deploys the Ethereum 2PC4BC Resource Manager Smart Contract on the ganache network.
• Deploys an instance of the SCIP Gateway.
• Configures the SCIP Gateway instance to communicate with the fabric and Ethereum blockchains.
• Configures the SCIP Gateway instance to use the deployed 2PC4BC Resource Manager Smart Contracts.

The no-cache optional argument ensures building fresh ganache and SCIP Gateway Docker images.

StopAll.sh

The script tears down the demo scenario. Invoke this script as follows:

./StopAll.sh

Sample Invocations

After deployment, you can test the setup using the following requests.
