Marco Posted on Twitter Earlier Today:
I have been the quality assurance and testing maintainer of Bitcoin Core for about 7 years now. In a challenging decision, I concluded to transition out of my role as maintainer.
I remain passionate about open source and Bitcoin and I am positive about the future, however being a maintainer is no longer a good fit for me personally. I am happy about my achievements and recognize that they would not have been possible without my sponsors.
I am grateful for @Okcoin having supported 3 out of my 7 years as maintainer, and for @paradigm having co-sponsored the last grant.
Four Bitcoin Core maintainers remain: Michael Ford, Hennadii Stepanov, Andrew Chow, Gloria Zhao.
