Why Kohaku Is Central to Ethereum’s 2025 Privacy Shift

Ethereum faces a challenge in privacy as it continues to prioritize security without effectively addressing user needs in wallets and apps. Despite advancements in privacy tools and protocols over the last decade, by 2025, the everyday use of privacy features remains cumbersome. Kohaku, introduced by Vitalik Buterin at Devcon 2025, aims to bridge this gap by providing a modular framework that includes a software development kit (SDK) and a browser extension wallet. Kohaku emphasizes risk-based transaction controls and supports both private and public modes for transactions. It integrates with existing privacy tools while focusing on usability, encouraging developers to adopt its principles. The project also raises questions about the balance between privacy and regulatory compliance, as it introduces features that allow selective transparency. Kohaku highlights the importance of creating a user-friendly experience in private blockchain interactions, aiming to simplify the use of Ethereum for everyday users while pushing the boundaries of privacy in adherence to regulatory frameworks.
