Asset transfer

This is setting up 2 orgs with 2 peers each and Org3 with 1 peer. All the orgs are joined through node js SDK client

It includes all the requirements as listed below.

1. Using Solo orderer

2. Fabric CA for certificates.

3. TLS is enabled

4. It includes a node.js app for doing all the setup activities:

   • create channels
   • join peers into channels
   • install chaincodes
   • instantiate chaincodes
   • invoke transactions
   • query the ledger

Node js app is a client invoking all the above activities for all peers/orgs

Transfer Consortium Setup

1. Org1 and Org2 with 2 peers each and Org3 with one peer.
2. Pre-created Member Service Providers (MSP) for authentication and identification
3. An Orderer using Kafka broker
4. Testchannel – this channel is public blockchain which all three orgs have read and write access to it.

Artifacts

• Crypto material has been generated and configured for all peers, the orderering node and CA containers.
• An Orderer genesis block (genesis.block) and channel configuration transaction (test.tx) has been pre generated.

Testing

Terminal Window 1

cd transferq3app (root folder)

./startServer.sh

• This launches the required network.
• Installs the fabric-client and fabric-ca-client node modules
• And, starts the node app on PORT 4000

Terminal Window 2

In order for the following shell script to properly parse the JSON, you must install jq

./setupNetwork.sh

This scripts goes through and

• enrolls org users,
• creates channel,
• join peers to channel,
• installs chaincode,
• instantiates chaincode,
• invokes chaincode to create assets
• invokes chaincode to transfer assets
• and queries chaincode.

A sample output looks like this:
