Developer ReportJanuary - June 2019The Developer Report is built on proprietary data from Electric CapitalElectric Capital is a digital asset management firm. We invest in programmable money and blockchain applications based on innovative technology, market adoption, and real use cases. We compile code, do security audits, run nodes to programmatically inspect the blockchain, have market intelligence based on proprietary software, and Follow us on Twitter ElectricCapitalData PipelineCurtis SpencerTwitter jubosContributorAvichal GargTwitter avichalContributorKen DeeterTwitter puntium2AuthorMaria ShenTwitter MariaShenWhy analyze developer activity31. Crypto networks are new open plats on which a new generation of applications will be built. 2. A clear, early signal for an emerging plat is engagement from developers. Developers build the applications that deliver value to end users and customers, and set off a virtuous cycle attracting more developers.3. The base layers of the crypto stack are uniquely open source, allowing us to analyze and understand developer engagement in an unprecedented way.4. Electric Capital tracks developer adoption as a leading indicator of where future value will be created and captured.Electric Capital indd 27,000 code repositories.analyzed 22M commits to find original code authors.across 3,400 crypto ecosystems.The Developer Reports compile findings from our ongoing research.4Help map the crypto ecosystemWe’ve opened our ecosystem map on GitHub so that anyone can contribute1. a pull request in https// or email We will use this data for our reports going forward.For more details on our ology, consult our appendix.5cutive Summary1. Despite market downturns in 2018, Full Time developers increased 13 year-over-year in June 2019 and are consolidating around high network value projects.2. Code commit volume is consistent but total monthly active developers are down 10 Y/Y.3. 80 of developer loss came from One Time per month and Part Time developers.4. The biggest developer drop-off came from projects outside of the Top 100 by network value.5. Smart Contracts, Infrastructure, and DeFi ecosystems continue to gain Full Time developers.6. Overall crypto ecosystems are approaching the size of well known open source projects such as Apache, but still has plenty of space to grow.6Part 0Overview7During Crypto Winter, code commits across 27k repositories remained flat8But at first glance, open source crypto developers appear to be down.9June 2018 7,671 monthly developersToday 6,842 monthly developersWhy does developer count appear to be downLet’s segment by1.
