Overview

Package configtx provides utilities to create and modify a channel configuration transaction. Channel transactions contain the configuration data defining members and policies for a system or application channel and can be used to either create or modify existing channels. Both the creation of a new channel or modification of an existing channel outputs an unsigned transaction represented in a protobuf binary format that must be signed by the requisite number of members such that the transaction fulfills the channel's modification policy.

See https://hyperledger-fabric.readthedocs.io/en/master/configtx.html#anatomy-of-a-configuration for an in-depth description of channel configuration's anatomy.
