PANews reported on November 18th that Vitalik Buterin showcased "Kohaku" at Devcon. This open-source framework provides privacy and security modules for Ethereum wallets and applications. Kohaku's current GitHub repository includes protocol packages such as Railgun and Privacy Pools, supporting fund shielding and proof of innocence. Privacy Pools uses association lists to prevent illicit fund obfuscation. In the demonstration, the wallet integrated Railgun provided privacy protection for publicly accessible funds; future integration with Mixnets and the ZK browser may follow. The Ethereum Foundation established the Privacy Cluster (47 people) and renamed the PSE team to Privacy Stewards to advance features such as "private voting" and "confidential DeFi."
