On March 12th, Bitcoin Core developer Andrew Chow said that code review is one of the biggest challenges Bitcoin currently faces.
Most Core developers are passionate about writing code for new features, but few enjoy the more mundane task of reviewing code submitted by their peers.
Chow said more contributors need to focus on code review, responding to the more than 300 PRs in Core’s GitHub repository. The community has a Bitcoin Core PR Review Club that meets weekly to help new contributors understand the review process.
