As we have seen in previous chapters, a Lightning node is a computer system that participates in the Lightning Network. The Lightning Network is not a product or company, it is a set of open standards that define a baseline for interoperability. As such, Lightning node software has been built by a variety of companies and community groups. The vast majority of Lightning software is _open source_, meaning that the source code is open and licensed in such as way as to enable collaboration, sharing and community participation in the development process. Similarly, the Lightning node implementations we will show in this chapter are all open source and collaborative developed.

Unlike Bitcoin, where the standard is defined by a _reference implementation_ in software (Bitcoin Core), in Lightning the standard is defined by a series of standards documents called _Basis of Lightning Technology (BOLT)_, found at the lightning-rfc repository at:

There is no reference implementation of the Lightning Network, but there are several competing, BOLT-compliant and interoperable implementations developed by different teams and organizations. The teams that develop software for the Lightning Network also contribute in the development and evolution of the BOLTs.

Another major difference between Lightning node software and Bitcoin node software is that Lightning nodes do not need to operate in "lockstep" with consensus rules, and can have extended functionality beyond the baseline of the BOLTS. Therefore, different teams may pursue various experimental features that, if successful and broadly deployed, may become part of the BOLTs later.

In this chapter you will learn how to set up each of the software packages for the most popular Lightning node implementations. We've presented them in alphabetical order to emphasize that we generally do not prefer or recommend one over the other. Each has its strengths and weaknesses and choosing one will depend on a variety of factors. Since they are developed in different programming languages (e.g. Go, C, etc.) your choice may also depend on your level of familiarity and expertise with a specific language and development toolset.
