Other than a preset configuration, anchor peer requires configuration
update to a live channel. An update transaction is first created using
configtxgen and a proper configuration file. This transaction is signed
and sent to ordering service. A new configuration block carrying this
anchor peer update transaction, is generated by ordering service. A
fter this block reaches all peers joining this channel, each peer commits
the block and now knows the anchor peer. Through gossiping each
peer now knows all peers, both inside and outside its own organization,
as channel members.
