Amazon Managed Blockchain Workshop

Amazon Managed Blockchain

Updated to support Fabric v1.4x

Building and deploying an application for Hyperledger Fabric on Amazon Managed Blockchain

This workshop builds a Hyperledger Fabric blockchain network using Amazon Managed Blockchain. Once the Fabric network has been created, you will deploy a 3-tier application that uses the Fabric network to track donations to a non-profit organisation, and track how those donations are spent by the non-profit. Donations and spending are tracked on a Hyperledger Fabric blockchain network with both donors and non-profits (NGO's) being members of the network. The 3-tier application consists of the following components:

  • Node.js / Angular user interface application, accessing services provided by a RESTful API
  • RESTful API, running as a Node.js Express application, using the Hyperledger Fabric Client SDK to query and invoke chaincode
  • Fabric Chaincode, written in Node.js, deployed to a Hyperledger Fabric network

This workshop will build a Hyperledger Fabric blockchain network using Amazon Managed Blockchain, deploy the chaincode, start the RESTful API server and finally run a UI application that uses the RESTful API to interact with the Fabric network. The workshop is divided into four parts:

  1. Building a Hyperledger Fabric blockchain network using Amazon Managed Blockchain. Instructions can be found in the folder: ngo-fabric
  2. Deploying the chaincode, or smart contract, that provides the donation and spend tracking functionality. Instructions can be found in the folder: ngo-chaincode
  3. Starting the RESTful API server that exposes the chaincode functions to client applications. Instructions can be found in the folder: ngo-rest-api
  4. Running the User Interface application. Instructions can be found in the folder: ngo-ui

Getting started

To build the network, deploy the chaincode, start the RESTful API server and run the application, follow the README instructions in parts 1-4, in this order:

  • Part 1: Start the workshop by building the Hyperledger Fabric blockchain network using Amazon Managed Blockchain.
  • Part 2: Deploy the non-profit chaincode.
  • Part 3: Run the RESTful API server.
  • Part 4: Run the application.
  • Part 5: Add a new member to the network.
  • Part 6: Read and write to the blockchain with Amazon API Gateway and AWS Lambda.
  • Part 7: Use blockchain events to notify users of NGO donations.
  • Part 8: Deploy Hyperledger Explorer.
  • Part 9: Integrating blockchain users with Amazon Cognito.

Cleanup

To clean up your resources delete the Hyperledger Fabric network managed by Amazon Managed Blockchain and the AWS CloudFormation template as follows:

  • In the AWS CloudFormation console delete the stack with the stack name <your network>-fabric-client-node
  • In the Amazon Managed Blockchain console delete the member for your network. This will delete the peer node, the member, and finally, the Fabric network (assuming you created only one member)
  • In the AWS Cloud9 console delete your AWS Cloud9 instance
