Demonstration of Invoice Financing on a Bank Network

Invoice Financing demo on a Bank Network using Hyperledger Fabric

The Bank Network is composed of two banks (organizations), Alpha and Beta. Each bank has two peer nodes.

Step 0: prepare a Fabric Node

Following the steps for a fabric node, which includes the prerequisite, fabric-samples and hyperledger fabric images.

cd fabric-samples

Step 1: bring up everything for demonstration

cd invfinancing-banknetwork
./starteverything.sh

Step 2: install the required SDK

npm install

Step 3: Enrol user-alpha and user-beta in wallet

node enrollAdmin-alpha.js
node registerUser-alpha.js

node enrollAdmin-beta.js
node registerUser-beta.js

ls wallet

Step 4: Perform client applications.

Substitute bank with alpha or beta to reflect which bank runs the client application.

Initialize a new invoice for a company: node initInv-bank.js <company> <invno> <invamount>. For example,

node initInv-alpha.js Alice inv-bob001 10000

Query an existing invoice: node queryInv-bank.js <company> <invno>. For example,

node queryInv-alpha.js Alice inv-bob001

Request loan on an existing invoice: node requestLoan-bank.js <company> <invno> <loanamt>. For example,

node requestLoan-alpha.js Alice inv-bob001 7000

You can try any combination of command, simulating query from other bank, or company applies amount exceeding the invoice amount, etc.

Step 5: Clean up

./teardowneverything.sh
