Welcome to Unit 5Lightning Nodes Hands-On with Polar
That's enough theory for now! It's time for another hands-on unit. We will look at the different node implementations in the Lightning Network and how they interoperate. This will give you the chance to set up a complete Bitcoin Lightning Network on your local machine using Lightning Polar, connecting to and programming nodes in Python, and exploring and comparing the different testing networks available to developers. You can start by reviewing the unit learning outcomes and then reviewing the unit resources.

AI Summary
This unit provides practical experience working with Lightning nodes. You will set up a local Lightning Network environment and experiment with different node implementations. Here are some key takeaways:
- Understand the role of Lightning nodes within the network.
- Examine how different node implementations interact and communicate.
- Explore how to set up a local Lightning Network using Polar.
- Recognize how developers test and experiment with Lightning infrastructure.
You can start by reviewing the unit learning outcomes and the unit resources.
