the Go programming language installed and your system is configured correctly. Now you need to create a subdirectory under your $gopath/src/to store your link code program. To make things simple, we provide a simple instruction: Mkdir-p $GOPATH/src/sacc cd $GOPATH/SRC/SACC We create a source file: Touch Sacc.go Housekeeping (coded) First let's prepare the code. Like every chain code, it implements the Init and invoke functions of the chain code. So let's use the GO Import statement to impo
