Summary
🤩
RockstarAnthony Towns is a seasoned backend developer with 18 years of experience focusing on Bitcoin Core and other cryptocurrency protocol implementations, currently working on Bitcoin Core at Paradigm from Brisbane. He has a long track record in open source—spanning Debian leadership and release engineering to substantial contributions across bitcoin/bitcoin, Bitcoin-ABC, Peercoin, PIVX and Core Lightning—often improving configuration handling, test infrastructure, and protocol safety. Anthony combines low-level C/C++ systems work (memory/CScript fixes, atomic ops) with rigorous test automation and refactoring to make complex distributed-systems codebases more modular and maintainable. His background as Debian Project Leader and release manager underscores strong release and process engineering instincts that complement his cryptography- and privacy-focused contributions (including early Lightning work). Notably, he pairs deep engineering chops with a long-standing commitment to reproducible, well-tested open source tooling and archive-level infrastructure.
