Transaction Shipping System to enable distributed transactions on Hyperledger Fabric
- Start your source and destination networks.
- Navigate to a location where you want to run transaction shipping system and clone the project:
git clone https://github.com/sm86/hyperledger-distributed-transactions.git - Open the repository :
cd hyperledger-distributed-transactions/ - Install the required dependencies :
npm install - Start the docker container for Couch:
./setup.sh - Initialize the database:
node app - verify your initialization by checking if there are 3 databases in http://localhost:5990/_utils/
Note: Make sure port 5990 is not being used. In case you need to change it, update the port in setup.sh and db/couchdb.js
This section is responsible for listening to transactions on the channel, filtering them as per policy and storing them on the transaction queue.
- Make sure source attributes are correct in config.json
- For the first time, we will enroll the admin
node enrollAdmin.js - Now, we will register user for our platform
node registerUser.js - Update/ create corresponding Network.yaml file in /source folder and you are now good to go.
- Start the blocklistner and this runs forever, listening and processing transactions:
node blocklistener.js
This section is responsible for retrieving from the transaction queue, processing to required format and sending the transaction onto destination. Make sure source attributes are correct in config.json
- For the first time, we will enroll the admin
node enrollAdmin.js - Now, we will register user for our platform
node registerUser.js - Update/ create corresponding Network.yaml file in /source folder and you are now good to go.
- Start the blocklistner and this runs forever, listening and processing transactions:
node shipTransactions.js - NOTE: Use 'forever' node package to keep the script running all time.
