description: Pantheon private network with privacy enabled quickstart tutorial # Private Network with Privacy Enabled Quickstart Tutorial The Private Network with Privacy Enabled Quickstart runs a private network of Pantheon and Orion nodes managed by Docker Compose. It is an expanded version of the [Private Network Quickstart](../Tutorials/Private-Network-Quickstart.md). You can use the [Block Explorer](../Tutorials/Private-Network-Quickstart.md#block-explorer), make [JSON-RPC requests](../Tutorials/Private-Network-Quickstart.md#run-json-rpc-requests), and create [transactions using Metamask](../Tutorials/Private-Network-Quickstart.md#creating-a-transaction-using-metamask) as described in the [Private Network Quickstart tutorial](../Tutorials/Private-Network-Quickstart.md). This tutorial describes how to use the examples provided in the EEAJS library to [create and send private transactions](#send-private-transactions-and-read-values). !!! important The quickstart runs a private network suitable for education or demonstration purposes. The quickstart is not intended for running production networks. ## Prerequisites To run this tutorial, you must have the following installed: - MacOS or Linux !!! important The Private Network Quickstart is not supported on Windows. If using Windows, run the quickstart inside a Linux VM such as Ubuntu. - [Docker and Docker-compose](https://docs.docker.com/compose/install/) - [Nodejs](https://nodejs.org/en/download/) - [Git command line](https://git-scm.com/) - [Curl command line](https://curl.haxx.se/download.html) ## Clone Pantheon Quickstart Source Code Clone the repository from the `pantheon-quickstart` repository where `` is replaced with the latest version (for example, `1.1.0`). ```bash tab="Command" git clone --branch https://github.com/PegaSysEng/pantheon-quickstart.git ``` ```bash tab="Example" git clone --branch 1.1.0 https://github.com/PegaSysEng/pantheon-quickstart.git ``` ## Clone EEAJS Libraries Clone the `PegaSysEng/eeajs` library: ```bash git clone https://github.com/PegaSysEng/eeajs.git ``` In the `eeajs` directory: ```bash npm install ``` ## Start the Private Network with Privacy Enabled In the `pantheon-quickstart/privacy` directory, start the network: ```bash ./run.sh ``` The Docker images are pulled and network started. Pulling the images takes a few minutes the first time. The network details are displayed. ```bash Name Command State Ports -------------------------------------------------------------------------------------------------------------------------- privacy_bootnode_1 /opt/pantheon/bootnode_sta ...

That is, the other nodes cannot access the contract. After deploying the contract, Event Emitter stores a value. In the `eeajs` directory, run `eventEmitter.js`: ```bash node example/eventEmitter.js ``` !!! tip The network takes a minute or so to get started. If you get a ` Error: socket hang up` error, the network isn't fully setup. Wait and then run the command again. The Event Emitter logs are displayed. ```bash Transaction Hash 0xe0776de9a9d4e30be0025c1308eed8bc45502cba9fe22c504a56e2fd95343e6f Waiting for transaction to be mined ...
