Carrone Detention Case Update

Ethereum core developer Federico Carrone was detained briefly in Turkey over a privacy tool research question and released after international support.

Carrone Freed After Detention in Turkey Linked to Privacy Tool Research

Ethereum core developer Federico Carrone, known to the community as Fede's Intern, spent 24 hours in detention in Turkey on a charge tied to a privacy tool. The Turkish Interior Minister accused him of helping others misuse Ethereum through a privacy tool. Carrone says the accusation traces back to a January 2022 research paper he co authored on Ethereum and Tornado Cash, describing the work as analysis of mixers and their properties, not illegal activity.

Friends and colleagues worldwide pressed for his release. UAE, UK, US, Europe, Argentina, and even members of the Solana ecosystem reached out to Turkish officials. Carrone was freed and has relocated to Europe while the case stays open; his lawyer is assembling a defense, and he has not ruled out returning to clear his name. The incident mirrors other high profile legal battles around Tornado Cash co founders and raises questions about how open source privacy research is treated under the law.

The episode is part of a wider crackdown on privacy research. Carrone donated 500000 USD worth of ETH to Roman Storms defense as a show of solidarity. The case underscores how support networks function in crypto space, but also draws attention to legal risk for donors. The community is watching how Turkey and other jurisdictions will balance privacy, security, and regulation.

The Turkish detention spotlights a broader tension between privacy research and the law. Open source privacy tools exist to defend user anonymity, but governments view them as dual use and sometimes as enabling wrongdoing. The lack of clear international norms creates a chilling effect on researchers who fear legal exposure for publishing or sharing code.

The case could influence policy, funding, and hiring in the crypto space. If prosecutors pursue these cases more aggressively, developers may move research to jurisdictions with clearer rules. The international response shows how communities can mobilize to support contributors, but the fundamental question remains where legitimate research ends and illegal activity begins. The pending verdict in Turkey and related cases will be watched by policymakers, investors, and researchers alike.
