The number of developers on the leading 4 blockchain projects continued to grow in the double-digits in July, totaling more than 1,200 on each project.
Ethereum and Polkadot have the largest totals of developers and consistency as a network and tooling continue to improve.
Increasing developer action indicates deep rooted determination to invest in infrastructure development regardless of overall market circumstance.
In July 2025, four blockchain networks broke a significant milestone by each having more than 1,200 actively contributing developers, marking an industry-wide trend of rising development activity. on-chain storage and GitHub tracking tools data indicate these platforms continued in double-digit growth rates in developer activity from the previous month, indicative of a general uptrend in core innovation and usage in ecosystems.

This dynamic development represents a turning point since blockchain communities mature away from speculation and towards value creation by developers. Analysts say that increased developer activity tends to occur prior to long-term maturity for a platform, bearing in mind that recurring code contributions often lead to improved products and robust infrastructure updates.
Ethereum, Polkadot, Cosmos, and Solana are some of the projects that boasted more than 1.2K developers in July. These environments not only led in absolute developer numbers but also recorded robust percentage gains, with figures of between 12% and 22% month-on-month.
Ethereum and Polkadot Lead in Volume and Consistency
Ethereum remained the most developer-rich ecosystem, having around 2,100 developers, thanks partly to its upgrades through modular upgrades, rollup integrations, and Layer-2 deployments. Polkadot was the next, with its more than 1,700 developers powered by parachain-based development and continuous updates of its cross-chain messaging protocol. The two projects have shown annual growth in their user base, further confirming them as high-utility platforms that are preferred by teams focused on infrastructure development.
Cosmos and Solana also experienced massive increases in their number of coders, with approximately 1,300-1,400 active developers on each platform. Cosmos enjoyed incremental interchain security and new validator modules, whereas the increase in Solana correlates with innovations in validator clients and the growth of its mobile stack. Despite all platforms varying in structure, the pattern towards comparable growth is an indicator of a larger shift in industry-wide engineering prioritization.
Double-Digit Developer Growth Reflects Long-Term Commitment
The rise in developer engagement is seen as a vital signal for investor confidence and long-term sustainability. Unlike short-lived trends driven by token speculation, active developer growth reflects meaningful work on scalability, tooling, security, and end-user applications. Such advancements are often key precursors to future adoption.
Industry experts also note that developer momentum is a leading metric for project relevance in bear or bull market cycles. As markets remain moderately volatile, platforms focusing on long-term infrastructure improvements are expected to maintain relevance regardless of price movements.
