The Bitcoin developer ecosystem is迎来 a turning point. The data released in 2025 sends a clear signal: the activity level of Bitcoin core development has risen sharply.

What does this mean? It indicates that the previous trend of waning development momentum has been reversed. Since the late 2010s, Bitcoin development had been in a slow state, but now this trend has finally reversed.

Looking at the numbers specifically. The discussion activity on the Bitcoin developer mailing list has increased by approximately 60% year-over-year, which is a significant rise. More intuitively, the contributor team—there were 135 developers involved in the Bitcoin core project throughout the year. This not only shows an increase in participation but also reflects a renewed focus and enthusiasm across the entire ecosystem.

Why did such a turning point occur in 2025? On one hand, Bitcoin’s market attention has continued to grow, naturally attracting more technical talent. On the other hand, some long-standing technical issues and upgrade directions have gradually reached consensus, giving developers a clearer sense of direction.

For holders, this signal is very important—a活跃的开发生态系统 means the protocol itself is continuously iterating and improving, with security and functionality both being enhanced.
