Fabric Source Analysis 6–GRPC Service GRPC Introduction GRPC is a multilingual open-source RPC technology developed by Google, which is used in fabric to implement remote calls between client and server. For example, the client defines an RPC service and generates the client code and the server-side code, and then runs the service-side code and the client-side code to realize the purpose of the client's C

Since my boss suddenly gave me an IBM Blockchain course website, I taught myself to finish two lessons from the blockchain provided by IBM and complete the compose-playground of this blockchain component in the fabric framework. This stand-alone construction is relatively simple, IBM's course has after-school this component related exercises and the document, therefore spent 2 days or so completed. Then the boss let me build a multi-machine cluster

When using shell commands for complex operations, the code tends to be complex and difficult to understand, and the Python scripting language is the equivalent of developing a common application, so maintenance and expansion are simpler, More importantly, the Python Ops tool fabric can automatically log on to other servers for a variety of operations, which is hard to do with the shell, but using the fabric
