Ethereum (ETH) crossed the 1 million cumulative developer milestone on June 15, further strengthening its role as the biggest developer ecosystem in the blockchain industry. The accomplishment was noted by Consensys co-founder Joseph Lubin, who referenced a goal first outlined in his keynote at DevCon5 in Osaka in 2019.
According to an analysis by Joseph Chalom, CEO of SharpLink and former head of digital assets strategy at BlackRock, Ethereum's ecosystem is now home to 1,012,824 developers.
In a post on X, Lubin celebrated the achievement, writing ‘We got there’ and saying that he envisioned the developer community surpassing one million contributors.
The numbers include the developers who have contributed code to the main network, L2 ecosystems, developer tools, client software, or infrastructure projects. Major networks included Optimism, Arbitrum, Base, zkSync, and Starknet.
Electric Capital's data shows that Ethereum had around 232,000 active developers in the last 12 months, which is higher than any other competing blockchain network.
Experienced developers continue to be the drivers of innovation in the ecosystem, according to data. 70% of all code commits were made by seasoned contributors, suggesting that Ethereum is being developed by a very active core community, while not necessarily a group of one-time contributors.
The milestone comes in response to a prediction made by Lubin in his DevCon5 2019 presentation, When 1 Million ETH Devs?
Since then, Ethereum has had a number of growth catalysts, such as the DeFi boom in 2020, the NFT craze in 2021, the Merge upgrade in 2022, and the explosive growth of Layer-2 solutions in 2023 and 2025.
The OneMillionDevs initiative, launched by Consensys, also helped in various ways, including developer education programs, hackathons, and onboarding, to encourage new developers to join the ecosystem.

Ethereum has seen a drop in the percentage of active crypto developers from 82% in 2020 to 31% in 2026, but it still outperforms the rest of the blockchain industry in the number of developers.
Chalom’s post highlights a key competitive question in crypto: ‘The decisive question…is not which chain is fastest, but where the best builders choose to build for the long term.’
The milestone is coming at a time when Ethereum is preparing for the Glamsterdam upgrade, which is scheduled for the third quarter of 2026. The upgrade aims to enhance scalability, decentralization, and Layer-1 performance.
