Hyperledger source code Analysis of Fabric Deliver means that the client obtains data from the ordering service via the Grpc interface (for example, data from a specified block). The Orderer node receives the request message, which is first given to the Deliver of the server structure in the Orderer.common.server package (SRV ab. Atomicbroadcast_deliverserver) Error method processing. This method further invokes the Handle of the deliverserver structu

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) Error method processing. This method will mainly call the Handle (SRV ab) of the HANDLERIM

General use of fabric, mostly with the remote interaction, and in the interaction, in addition to the logic of simple code, time is also accompanied by the transmission of files, and there may be a lot of files in the file. Whether we can make a judgment, if the file exists, then we do not upload, look at the code # for a test @task @roles ("Mgmt") def Test (): if Int (run ("[E '/etc/passwd1 '] echo 11 | | echo ") = = one: print" Yes, f

Root CA CAs are generally grouped by organization, that is, ORG1,ORG2,ORG3 have their own CAs. When the CA is started, two environment variables, fabric_ca_server_ca_certfile and Fabric_ca_server_ca_keyfile, are set. What happens if you don't set these two up? In fact, if not set, the CA server will generate these two files on its own according to the default CA CONFIG. This time the CA is called the ROOTCA. · Fabric_ca_server_ca_certfile is the certificate of the current CA (public key) · Fabri
