- Ethereum co-founder Vitalik Buterin urges the crypto community to adopt copyleft licenses.
- This shift aims to ensure shared innovation and prevent the sector from moving away from its open-source roots.
Ethereum’s co-creator, Vitalik Buterin, believes the cryptocurrency world is drifting too far from its original open-source principles. He is now strongly encouraging developers to use copyleft licenses, a type of software license designed to keep innovation truly open and shared among everyone.
Why Copyleft? A Shift in Strategy
Buterin’s new stance, detailed in a recent post, marks a change from his earlier support for more permissive licenses. Permissive licenses allow anyone to freely use, modify, and reuse code without many rules.
However, copyleft is different: it not only allows code sharing but requires that any new projects built using that code must also be open for everyone to see and use, under the same terms.
This change comes because Buterin feels the crypto space has become more competitive and mercenary. He argues that we can no longer simply rely on people sharing their work purely out of niceness. In a more commercialized crypto world, voluntary sharing isn’t enough to keep things truly open.
Copyleft acts as a practical solution, ensuring that public contributions benefit the entire ecosystem rather than just a few private companies. It pushes for a give-and-take approach, where using someone’s open code means you also make your new work open.
While Buterin acknowledges that copyleft might have some challenges, like requiring code to be shared even if it hasn’t been widely distributed, he believes the benefits outweigh the negatives, especially now that open-source software is common everywhere.
He sees copyleft as a “neutral way of incentivizing more diffusion,” helping to build a shared pool of code that grows when people contribute back.
Crypto investor Adam Cochran has supported Buterin’s view, agreeing with the core idea even with minor edge cases. This push for stronger open-source rules comes as the crypto industry grapples with growing centralization and private, closed-off innovations. Buterin hopes this will bring the sector back to its original values of teamwork and transparency.
Ethereum Staking Continues to Grow
Separately, but showing continued strength in the Ethereum network, staking on the platform has reached a great milestone. Over 35 million ETH, which is more than 28.3% of the total supply, is now locked into Ethereum’s proof-of-stake system. This shows a clear trend of investors choosing to earn rewards from their ETH rather than selling it.
In the first half of June alone, over 500,000 ETH was staked. Large players like Lido handle more than 25% of all staked ETH, while major exchanges like Binance and Coinbase also account for great portions. Coinbase, in particular, has become Ethereum’s largest node operator, managing over 11.4% of staked ETH through its validators.
This surge in staking is happening alongside intense whale accumulation, with large investors adding over 871,000 ETH in a single day on June 12th, marking the highest daily inflow in 2025. This has pushed total holdings in wallets with 1,000 to 10,000 ETH past 14.3 million ETH, according to Glassnode data. ETH is currently trading at $2,550, down 1% in the last 24 hours.
