transactions, and this differentiation is highlighted in Hyperledger Fabric through its fundamental role in the entire transaction flow, from proposal and endorsement, to ordering, validation and commitment Authority, CA4, which is used to issue certificates to administrators and network nodes. CA4 plays a key role in our network because it dispenses X.509 certificates that can be used to identify components as ordering service node O4 performs a very different role for the channel C1 than it does for the network N. When acting at the channel level, O4’s role is to gather transactions and distribute blocks inside
