Hyperledger Fabric Hello World is about building your first blockchain network. We will make use of fabric-samples provided by Hyperledger. The first Blockchain network will be built using Docker containers. The first network will result in running containers representing some of the following:
The key point to note that the Hyperledger Fabric executes blockchain transactions within a channel. If the channel name is not provided, a default channel name such as mychannel is used.
./byfn.sh -h
Execution of above command would show following on sole:
Figure 1. byfn.sh execution
./byfn.sh -m generate
Above command does some of the following:
Execute the following command to bring the Blockchain network up and running.
./byfn.sh -m up
Following happens as a result of bringing up the network:
Figure 2. Create Hyperledger Channel
Figure 3. Peer Nodes join Hyperledger Channel
Figure 4. Hyperledger Fabric Install Chaincode
Following command can be executed to bring down the network
./byfn.sh -m down
Figure 5. Hyperledger – Bring Down Blockchain Network
Following represents the docker containers which got started to bring up the network:
