Ethernet is the fastest growing blockchain developer in 2025 with 16,000+ developers; Solana explodes, Bitcoin is third, and blockchain developers transform developer ecosystems.
In 2025, Ethereum has established itself as the most successful blockchain developer ecosystem, with over 16,000 new developers joining between January and September.
Ethereum Foundation records (referencing Electric Capital data) suggest that with this surge, Ethereum has gone way ahead of all blockchain projects in the entire world.

The total number of active developers currently runs at 31,869 users of both the core network and layer-2 solutions like Arbitrum and Optimism.
These numbers do not include cases of counting developers who can work on several networks within the Ethereum ecosystem.
This development supports Ethereum as the leader in blockchain innovation and smart contract development.
Solana is second with more than 11,500 new developers in 2025, and its total number of active developers is 17,708.
Although this is a remarkable growth, the Solana Foundation has raised concerns regarding the fact that the data collected by Electric Capital could underreport its true developer count by approximately 7,800, given the difficulty in monitoring all the Solana activity.
The developer base across Solana has increased 29.1% over the past year and exceeded by a staggering 61.7% in the previous two years, ranking it as one of the fastest-growing ecosystems in blockchain development.
However, other specialists warn that these numbers may be temporarily over-inflated due to the use of AI-assisted coding and projects in hackathons.
Bitcoin, the first project of blockchain technology, follows in third place in the attraction of new developers in 2025, attracting nearly 7,500 new contributors each year. The number of active developers in it has reached 11,036.
Although its growth rate in terms of developers is lower than that of Ethereum and Solana, Bitcoin can still be regarded as an important ecosystem whose developers continue to show interest in enhancing its underlying protocol and introducing additional tools to support it.
This dynamic of developer growth underscores Ethereum as the blockchain technology at the forefront of innovation in 2025 due to its established and broad ecosystem, as Solana carries on with its blistering growth. Bitcoin has secured a strong position in the cryptocurrency market, supported by a dedicated base of developers.
