Event-catcher for Hyperledger Fabric.
It connects to a node in the Hyperledger fabric network to listen for events. It has the following features.
- Listening raw block events.
- Listenin filtered block events.
- Listening block and private data events.
- Listening chaincode events.
- Listen to block events on multiple channel.
- Listen to chaincode events on multiple chaincodes.
- Gateway-SDK is used.
Go to the release page and download docker-compose files.
Before you start, get your Hyperledger Fabric network up and running. Create a channel, upload a chaincode (or multiple chaincodes) and make a few transactions.
mkdir paratonnerreTest
cd paratonnerreTestCopy all three files into "paratonnerreTest" folder.
In order to run the application, you need to prepare the following 3 files.
- user certificate (cert.pem)
- user private key (*_sk)
- peer tls certificate (ca.crt)
< For Fabric Samples Test Network >
You can access the files by following the path below in the test network in the Fabric samples repository.
For User Certificate:
- fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/signcerts/cert.pem
For User Private Key: (After copy-paste, change name to priv_sk)
- fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/keystore/< private key file >
For Peer Tls Certificate:
- fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
Download files and put into paratonnerreTest folder.

- MSP_ID=Org1MSP
- PEER_ENDPOINT=localhost:7051
- PEER_HOST_ALIAS=peer0.org1.example.com
