+#
+# This verification makes use of two fundamental tools, which are necessary to
+# create a functioning transactional network with digital signature validation
+# and access control:
+#
+# * cryptogen - generates the x509 certificates used to identify and
+#   authenticate the various components in the network.
+# * configtxgen - generates the requisite configuration artifacts for orderer
+#   bootstrap and channel creation.
+#
+# Each tool consumes a configuration yaml file, within which we specify the topology
+# of our network (cryptogen) and the location of our certificates for various
+# configuration operations (configtxgen).  Once the tools have been successfully run,
+# we are able to launch our network.  More detail on the tools and the structure of

+# channel transaction file is broadcast to the orderer at channel creation
+# time.  The anchor peer transactions, as the name might suggest, specify each
+# Org's anchor peer on this channel.
+#
+# Configtxgen consumes a file - ``configtx.yaml`` - that contains the definitions
+# for the sample network. There are three members - one Orderer Org (``OrdererOrg``)
+# and two Peer Orgs (``Org1`` & ``Org2``) each managing and maintaining two peer nodes.
+# This file also specifies a consortium - ``SampleConsortium`` - consisting of our
+# two Peer Orgs.  Pay specific attention to the "Profiles" section at the top of
+# this file.  You will notice that we have two unique headers. One for the orderer genesis
+# block - ``TwoOrgsOrdererGenesis`` - and one for our channel - ``TwoOrgsChannel``.
+# These headers are important, as we will pass them in as arguments when we create
+# our artifacts.  This file also contains two additional specifications that are worth
+# noting.  Firstly, we specify the anchor peers for each Peer Org
+# (``peer0.org1.example.com`` & ``peer0.org2.example.com``).  Secondly, we point to
+# the location of the MSP directory for each member, in turn allowing us to store the
+# root certificates for each Org in the orderer genesis block.  This is a critical
+# concept. Now any network entity communicating with the ordering service can have
+# its digital signature verified.
