Bitcoin Core PR Review Club

A weekly review club for Bitcoin Core PRs

What is this? A weekly club for reviewing Bitcoin Core PRs at 17:00 UTC on Wednesdays in the #bitcoin-core-pr-reviews IRC channel on libera.chat.

What’s it for? To help newer contributors learn about the Bitcoin Core review process. The review club is not primarily intended to help open PRs get merged.

Who should take part? Anyone who wants to learn about contributing to Bitcoin Core. All are welcome to come and ask questions!

What’s the benefit for participants? Reviewing and testing PRs is the best way to start contributing to Bitcoin Core, but it’s difficult to know where to start. There are hundreds of open PRs, many require a lot of contextual knowledge, and contributors and reviewers often use unfamiliar terminology. The review club will give you the tools and knowledge you need in order to take part in the Bitcoin Core review process on GitHub.

How do I take part? Just show up on IRC! See Attending your first PR Review Club for more tips on how to participate.

Who runs this? Upcoming meetings are scheduled by Bitcoin Core contributor glozow. The meetings are hosted by a variety of Bitcoin Core contributors. See some of our previous hosts.
