The command line interface allows developers to download and run a private node on a local machine.
This allows developers to carry out testing without having to connect to the test net or the main net, which is a lot faster and efficient.
The Command Line Interface (CLI) is a part of Ontology's core implementation.
The CLI, along with the node can be downloaded by executing the following shell commands-
git clone https://github.com/ontio/ontology.git
go get github.com/ontio/ontology
