written in Go and loaded using the Go plugin package. A plugin includes a main package with exported symbols and is built with the command go build -buildmode=plugin. Every system chaincode must implement func New() shim.Chaincode in the main package. An example can be found in the repository at examples/plugin/scc. Existing chaincodes such as the QSCC can also serve as templates for certain features, such things like logging and testing. Note: On imported packages: the Go standard library requires that a plugin must include the same version of imported packages as the host application (Fabric, in this case)
