The development enthusiasm for Bitcoin shows a significant uptick in 2025. According to data statistics, the number of emails in the Bitcoin developer mailing list has increased by approximately 60% compared to the previous period, which is a notable improvement.

More importantly, the number of contributors has increased. Currently, 135 different developers have contributed code to the Bitcoin Core codebase, up from 112 in 2024. This number carries an important signal — since peaking in 2018, the number of Bitcoin developers has been declining, but now there is finally a reversal.

What does this indicate? It suggests that more people are paying attention to the technical iteration of Bitcoin Core. Whether it’s security improvements or feature optimizations, more developers need to participate. This resurgence in development activity more or less reflects the entire ecosystem’s re-evaluation of Bitcoin’s technological prospects. As the Bitcoin ecosystem develops in 2025, we have reason to expect more technological innovation and improvements.

Finally, the day has arrived. The signal of developer resurgence is very clear. The number of Bitcoin developers has been declining since 2018, indicating that these past few years have indeed been lackluster. It's quite exciting to see a turnaround now. A 60% increase in emails, 135 new contributors... it really feels like the ecosystem has awakened.

Finally, the BTC developers are warming up again. It's been truly exhausting over these past 6+ years. Why does it feel like everyone in the crypto space has woken up and is working on technology together? 135 contributors—this number feels just right to me... a signal of reversal is coming. Developers increase > community enthusiasm > technological breakthroughs, this cycle needs to turn like this. Wait a minute, could it be that the bull market is here, and everyone has come out? Stop talking, this is exactly how BTC should be—purely driven by technology.

Finally seeing the number of developers rise again, this is not a false alarm.

A 60% increase in emails sounds impressive, but looking at it from another perspective—could this be the herd effect after a price increase? The number of developers has gone from 112 to 135. From a game theory perspective, it's the change in the incentive mechanism that truly acts as the trigger. What about on-chain evidence? Among these 135 contributors, how many are genuinely committed to deep engagement, and how many are just riding the market hype to fish in troubled waters? Data can be deceptive.

Wait, the number of developers increased from 112 to 135, which is a real bottom signal... much more reliable than just looking at candlestick charts.
