In the first contact with the fabric is usually directly follow the Wiki tutorial step-by-step installation of the configuration, execute a series of commands, and eventually run it up, but many people on the running process and its basic knowledge point may not be very familiar. Based on this today I will take the $fabric_root/examples/e2e_cli/classic demo as an example to share some of my understanding, hope can be helpful to the beginner. Genera

time, which may miss this "virtual value" during this process. COUCHDB is run as a standalone database process with peer, so there are additional considerations for setup, management, and operation. We can consider starting with the default embedded Leveldb, which can be transferred to COUCHDB if additional complex rich queries are required. modeling Chaincode Asset data as JSON is a good practice so that we can execute the complex rich queries we need in the future. Using the CouchDB in Ch
