Vitalik Buterin has unveiled Kohaku, a new open-source privacy solution for Ethereum, at Devcon. This initiative directly addresses growing concerns about transaction transparency on the blockchain. Kohaku is designed with a modular architecture, enabling developers to build privacy-focused wallets without relying on a central authority. This decentralized approach aims to empower users with greater control over their personal data and financial activity. The project's roadmap includes future expansion to incorporate mixnets and zero-knowledge (ZK) based browsers, further strengthening its privacy capabilities. Buterin's personal demonstration highlights the significance of Kohaku in the ongoing effort to enhance privacy and security within the Ethereum ecosystem, fostering greater user trust and adoption. ```
