Hyperledger source code Analysis of Fabric Broadcast means that the client sends the request message (for example, after the endorsement transaction is completed) to the ordering service via the Grpc interface. These request messages are given to the broadcast (SRV ab) of the server structure in the Orderer.common.server package. Atomicbroadcast_broadcastserver)

The previous analysis program looked at the details of the analysis, so without the concept of framework, took two days to analyze the Hyperledger fabric architecture design, analysis of the program does not reference any information, such as error welcome correction, common progress. The author has the following questions before the detailed analysis procedure: 1) How the CLI (command line) client sends a
