We talked to Brink grant recipient Hennadii Stepanov about how he started contributing to Bitcoin Core and his priorities for the next year.
I first heard about Bitcoin from friends at the beginning of 2017. I had some Linux system admin experience and at the time was maintaining a Java-based GUI of an accounting application for a credit union. Eventually, I spun up an old laptop to run Bitcoin Core but the laptop happened to have a small HDD and space was limited. I discovered that Bitcoin Core had a pruning option, which I tried using. While reviewing the related code, I spotted a bug in the documentation and decided to file my first Bitcoin Core pull request, #13844. It was merged and I was encouraged to see that I could help make improvements to the codebase.
Over 500 commits later and much like that first PR, I find that most of my contributions are motivated by my personal experience as a Core user. I mostly contribute to the GUI (where I was recently made a maintainer), peer-to-peer code, concurrency code, and the build system. I am excited to continue contributing to Bitcoin Core and have a few different areas of focus over the next year.
First and foremost I plan to use my time reviewing as many PRs as possible. Reviews can be scarce on the project and for such a security-critical application, it’s vitally important that all code changes are thoroughly reviewed.
In the peer-to-peer code, I’ll spend some time researching additional criteria for estimating the quality of a node’s peers. I hope to decrease the number of different heuristics currently being used and to simplify peer scoring.
Lastly, I will continue to keep the Ukrainian language translation for the Bitcoin Core project up to date since it was previously abandoned.
I’m proud of the contributions I made while sponsored by CardCoins and Payvant and look forward to continuing my work with Brink’s support.
