Bitcoin development has shifted from a weekend hobby for cypherpunks to a professionalized workforce. Who is funding the code?
% of commits from sponsored vs independent developers over time.
Distribution of maintainers by sponsoring entity.
Bitcoin never sleeps. What began as a weekend project for a handful of cypherpunks has evolved into a global 24/7 industrial-grade operation.
The "follow-the-sun" model: When US devs log off, Europe and Asia Pacific maintain the momentum. Review activity never hits zero.
Weekend coding has plummeted from 40% (2009) to ~8% today. Bitcoin is no longer a hobby; it is a professional vocation.
Bitcoin's recruitment is shifting geographical gears. Over the last decade, we've moved from a predominantly North American and European base to a truly global professionalized workforce.
While "Western Hubs" remain the primary recruitment engine, the **geopolitical footprint** of Bitcoin's code is expanding.
We are seeing a notable surge in **Asia Pacific** participation, while regions like **Africa** have established a consistent yearly footprint for the first time.
Note: "Undisclosed" data (~65% of contributors) reflects the project's cypherpunk roots and the cultural value of pseudonymity.
Workforce Stability: Tracks the stability of the active project team. It focuses on "Regulars" (contributors with 3+ commits in a given year), regardless of when they first joined, and shows how many remain active in subsequent years. This measures system continuity.
