Hyperledger Composer Environment Channels

Q

What Channels are included in my Hyperledger Composer Environment?

✍: FYIcenter.com

A

In the fabric-dev-servers.tar.gz package, only one channel, "composerchannel", is created in the Hyperledger Composer Developer Environment.

The peer node peer0.org1.example.com has been configured to this channel. You can only deploy Hyperledger Composer blockchain business networks into an existing channel.

Channels are used in Hyperledger Fabric to divide peer nodes into groups to provide better security control.
