Crypto Developers Are Leaving for AI as GitHub Activity Surges

Blockchain development is shrinking fast. Weekly crypto code commits have dropped roughly 75% since early 2025, falling from approximately 850,000 to just 210,000, while active developers in the space declined by 56% to around 4,600, according to analytics platform Artemis. The numbers paint a clear picture of an industry losing momentum.

The contrast with the broader tech world is striking. GitHub welcomed around 36 million new developers in 2025 alone, pushing its global total past 180 million users, with platform-wide commit activity growing approximately 25% year over year. A significant portion of that growth is being driven by artificial intelligence. The platform now hosts over 4.3 million AI-related repositories, imports of large language model SDKs surged 178% to more than 1.1 million repositories, and generative AI projects are pulling in over one million monthly contributors.

The data strongly suggests developers are shifting their focus toward AI infrastructure and away from blockchain. Machine learning notebooks grew around 75%, AI deployment tools jumped roughly 120%, and TypeScript overtook Python and JavaScript as GitHub's most-used programming language after gaining over a million new contributors in just one year.

Within crypto, losses are widespread. Ethereum's weekly active developers fell 34% to around 2,800. Solana dropped 40% to roughly 940 developers, while Coinbase's Base network shed 52%. Newer chains suffered even steeper declines, with BNB Chain commits falling as much as 85%.

That said, the sector may be consolidating rather than collapsing entirely. Experienced developers with over two years of tenure grew 27% and now account for roughly 70% of all commits. The sharpest losses are among newer, part-time contributors.

Crypto development has historically rebounded with bull markets, but the growing appeal of AI careers backed by heavy venture funding makes this particular talent shift harder to reverse.
