ChainCatcher reported that Ethereum co-founder Vitalik Buterin retweeted the Kohaku roadmap, stating that full-stack privacy and security are Ethereum's top priorities. According to his retweet, Kohaku is a set of primitives that provide security and privacy for wallets.
The core goals of Kohaku are: to provide an SDK with powerful privacy/security primitives; to build a reference implementation wallet for advanced users based on this SDK; and to collaborate with other wallets to implement all or part of the SDK according to their needs.
