- Ethereum launches Kohaku roadmap to enhance wallet privacy via modular framework, prioritizing user-controlled security tools.

- SDK enables customizable privacy modules, Helios light client reduces third-party dependency, and ZK-based recovery tools streamline account management.

- Post-quantum "killswitch" and universal hardware app address emerging threats, while Privacy Cluster embeds privacy into Ethereum's core protocol.

- Future plans include kernel-level browser, AI transaction scoring, and 2026 privacy-preserving account abstraction to unify public/private fund control.

- Initiative aims to retain privacy-conscious users through open-source collaboration, balancing regulatory compliance with decentralized security innovation.

Ethereum has launched the Kohaku roadmap, a comprehensive initiative aimed at enhancing wallet privacy and security across its network. Coordinated by

Ethereum
Foundation (EF) developer Nicolas Consigny, the project introduces a modular privacy framework designed for developers and advanced users. Vitalik Buterin, Ethereum co-founder, emphasized that full-stack privacy and security are "first-class priorities" for the network, marking a strategic shift toward user-controlled confidentiality toolsThe Ethereum Foundation releases roadmap for private wallets,[1]. The initiative includes a software development kit (SDK) enabling other wallets to integrate privacy features either fully or in targeted modules, fostering a decentralized approach to securityEthereum Launches Kohaku Roadmap to Strengthen Wallet Privacy,[2].

Kohaku's architecture is built on a plugin system, allowing developers to customize wallets and add privacy protocols incrementally. The first phase integrates the Helios light client, enabling users to validate blockchain data locally without relying on centralized RPC providers. This reduces dependency on third-party services for transaction verification, a key vulnerability in current systemsThe Ethereum Foundation releases roadmap for private wallets,[1]. Additionally, the roadmap introduces a "wallet connection kit" for peer-to-peer RPC communication and tools like ZKemail, ZKpassport, and Anon Adhar for zero-knowledge recovery. These tools aim to streamline social recovery processes while maintaining privacy, addressing common pain points in account managementEthereum Devs Unveil Kohaku Roadmap to Boost Wallet Privacy …,[3].

The Ethereum Foundation has also prioritized post-quantum security, incorporating a "killswitch" that allows users to enable accounts using Falcon or Dilithium verifiers. These cryptographic schemes are optimized for Solidity and designed to protect against quantum computing threats, a growing concern in the crypto spaceEthereum Devs Unveil Kohaku Roadmap to Boost Wallet Privacy …,[3]. Furthermore, the project includes a universal Ethereum hardware app, aiming to eliminate vendor lock-in and support advanced features like zero-knowledge hardware signers compatible with existing privacy protocolsKohaku Unveils Ethereum's Privacy and Security Roadmap,[4].

To institutionalize privacy efforts, the EF has formed the Privacy Cluster, a group of 47 engineers, researchers, and cryptographers. This initiative, alongside the Privacy and Scaling Explorations (PSE) team, focuses on embedding privacy tools directly into Ethereum's Layer 1 protocol. Key objectives include private payments, confidential identity systems, and zero-knowledge infrastructure, ensuring privacy is a foundational aspect of the network rather than an afterthoughtThe Ethereum Foundation releases roadmap for private wallets,[1]. Collaborations with entities like Ambire, Railgun, and Helios underscore the project's open-source ethos, with contributions welcomed via GitHub repositoriesKohaku Roadmap - HackMD,[5].

Looking ahead, Kohaku outlines ambitious future directions. These include a native Ethereum browser designed to operate closer to the system kernel, enhancing dApp security through IPFS-based interfaces and privacy-focused front-end languages. The roadmap also explores local AI transaction scoring to assess risk levels without exposing user data and plans for privacy-preserving account abstraction by 2026. This would leverage client-side zero-knowledge proofs to unify control over public and private funds, a critical step toward seamless user experiencesETHDILITHIUM and ETHFALCON for Ethereum PQ Era,[6].

The launch of Kohaku reflects Ethereum's broader commitment to addressing regulatory and technical challenges in the privacy space. By integrating modular tools and fostering collaboration, the network aims to retain privacy-conscious users while aligning with evolving security standards. As the project progresses, its success will depend on developer adoption and the scalability of its protocols across Layer 2 networks. The Ethereum Foundation's emphasis on open-source development and community engagement positions Kohaku as a pivotal step in the ecosystem's evolution toward a more secure and private digital futureThe Ethereum Foundation releases roadmap for private wallets,[1]Ethereum Launches Kohaku Roadmap to Strengthen Wallet Privacy,[2]Ethereum Devs Unveil Kohaku Roadmap to Boost Wallet Privacy …,[3]Kohaku Unveils Ethereum's Privacy and Security Roadmap,[4]Kohaku Roadmap - HackMD,[5]ETHDILITHIUM and ETHFALCON for Ethereum PQ Era,[6].
