Node Academy: Chapter 3A - Installing and syncing Bitcoin Core

Leo guides viewers through the process of installing Bitcoin Core, the most popular implementation of a Bitcoin node. The video covers three installation methods: compiling from source, downloading the source code, and installing from the Ubuntu Snap Store. The presenter recommends installing Bitcoin Core from source for those interested in open source and self-sovereign software.

For the first method, compiling from source, the video explains the process step by step. It begins with preparing the machine by installing necessary software packages using the provided command. The source code is then downloaded from the Bitcoin Core GitHub repository, and a specific version is selected. After generating a makefile and configuring the system, the code is compiled and installed permanently on the machine.

The second method involves downloading the binary from the Bitcoin Core project's website. Viewers are guided on creating a separate folder for downloads, and then the appropriate binary file is downloaded based on the operating system. The compressed file is unpacked, and the binaries are moved to a location where the system can access them permanently.

The third method, installing from the Ubuntu Snap Store, is described as the most straightforward option. By executing a single command, viewers can install Bitcoin Core directly from the Ubuntu software repository. Additional instructions are provided to grant access to external drives if needed.

At the end of each installation method, the presenter congratulates viewers on successfully installing Bitcoin Core and suggests proceeding to the next guide for configuration.
