ETH: Ecosystem Developers by Commitment
Ethereum Ecosystem Developers by Commitment: daily data through 1 Nov 2026.
The developers of the Ethereum ecosystem by how much they contribute: full-time, part-time and one-time, with the number who started in crypto less than a year ago.
Why use it. Full-time developers are the core that ships most of the work. A network can hold its headline count on one-time contributors while its full-timers leave; the new-developer line shows whether it is still drawing people in. How to read it. The three commitment groups follow the source's classification by how many days a developer contributed over the last 84 days; the exact thresholds are in its documentation. New is counted by the first commit in crypto. Read the lines against their own history rather than against another ecosystem.
Calculation. Each day: the source's classification of the developers of the trailing 28 days by their contribution over 84 days and by the date of their first commit to a crypto repository. Source: Open Dev Data by Electric Capital (opendevdata.org), used under CC BY 4.0: daily snapshots of developer activity in public repositories that its open taxonomy assigns to each ecosystem, on its own 28-day rolling method. The taxonomy is maintained by Electric Capital and contributors, so an ecosystem can gain or lose repositories over time, which moves the past as well. The chart ends about a week behind today, at the source's own pace; only public work on GitHub is seen.
