Use Private Net for development
As a developer, it would be a good idea to run an NEO private-net on your own machine. Deploying you smart contracts on the test-net should be the final step of your development(before publishing on the main-net), so all the development, testing and debugging should be done on your own private-net. Today I'm here to show you how to easily set up an NEO private net using
python on Ubuntu Linux

- If you don't have
Dockeralready, you can visit their this Installation Guild on their official website.
Step 1: Clone the Docker Image provided by City of Zion
City of Zion is an independent group of open source developers, designers and translators formed to support the NEO BlockChain, they have built the docker image of a pre-build private network, with a wallet file storing all the 100 million NEO, which we will use later.
It's much easier for people to set up a private Net with the docker image, basically, all we have to do is clone it and then run the image on our local machine.
docker pull cityofzion/neo-privatenet
Step 2: Run the docker Image
Simply run the docker image with the following command:
docker run --rm -d --name neo-privatenet -p 20333-20336:20333-20336/tcp -p 30333-30336:30333-30336/tcp cityofzion/neo-privatenet
After running the image, you should be able to see the image status with command:
Yay! Now the Neo Private net is up and running on our machine. Next, we will try to use
neo-python to interact with the private net.
Step 3: Install
First of all, we need to make sure we have python3.6, also install some required packages:
apt-get install software-properties-common python-software-properties add-apt-repository ppa:deadsnakes/ppa apt-get update apt-get install python3.6 python3.6-dev python3.6-venv python3-pip libleveldb-dev libssl-dev g++
git clone https://github.com/CityOfZion/neo-python
(Recommanded)Make a virtual environment with python3.6
cd neo-python # get into the neo-python repository python3.6 -m venv venv source venv/bin/activate
pip3 install -U setuptools pip wheel pip3 install -e .
For more detail about setting up
python neo, you can visit their GitHub Readme
Step 4: Use neo-python to connect to the private net:
Delete Old private-net chain:
rm -rf Chains/privnet
Open the CLI connected to the private-net
python prompt.py -p
-p parameter means private net, you can use prompt.py to interact with main-net or test-net as well.
After entering this command, you should see a CLI opened.
Step 5: Download the wallet file and get your 100 million NEO!
Download the wallet and save it under the
neo-python directory: https://s3.amazonaws.com/neo-experiments/neo-privnet.wallet
In the CLI, command:
open wallet neo-privnet.wallet
and then enter the password:
coz (for City Of Zion)
You can enter
wallet again to see basic information about this wallet. You should be able to see the
100000000 NEO under
Now you have a NEO private-net running with a wallet containning all the assets on this blockchain! We're so rich right now! can start our development :)
I'm still playing around with NEO contract development, once I got something I'll share it on here on Steemit too:)
