7.3 Hyperleger Fabric - Commercial paper tutorial

This tutorial will show you how to install and use a commercial paper sample application and smart contract.

In this tutorial two organizations, MagnetoCorp and DigiBank, trade commercial paper with each other using Paper-Net, a Hyperledger Fabric blockchain network.

In this tutorial, we will operate Org1 of the test network as DigiBank and Org2 as MagnetoCorp

The commercial paper tutorial allows you to act as two organizations by providing two separate folders for DigiBank and MagnetoCorp. The two folders contain the smart contracts and application files for each organization. Because the two organizations have different roles in the trading of the commercial paper, the application files are different for each organization.

 --lang node \
 --path ./contract \
 --label cp_0

$ peer lifecycle chaincode install cp.tar.gz
