We have hosted the application kohaku in order to run this application in our online workstations with Wine or directly.

Quick description about kohaku:

Kohaku is an open-source initiative by the Ethereum Foundation aimed at bringing privacy-by-default tooling into the Ethereum ecosystem. It comprises an SDK of privacy primitives, a reference wallet implementation (browser extension), and a collaboration platform for existing wallet teams to adopt composable privacy building blocks. The project recognizes that privacy leaks in Ethereum go beyond just on-chain visibility — they include RPC endpoints exposing IPs, address reuse across dApps, and metadata captured by analytics or monitoring systems. Kohaku addresses privacy holistically: from local light-client verification (to reduce reliance on centralized RPCs) to per-dApp account isolation (so one user session cannot be correlated across services). It also integrates with existing privacy protocols (e.g., shielded transaction pools) and envisions long-term capabilities like post-quantum signatures, hardware wallet hooks, and minimal-trust data queries (TEE/ORAM or PIR).

Features:

• SDK bundling modular privacy and security primitives for wallet integration
• Reference wallet implementation showing per-dApp address isolation and shielded transactions
• Built-in light client verification to reduce dependency on centralized RPCs and preserve trustless state
• Integration with multiple privacy protocols (e.g., shielded pools) for private send/receive flows
• Metadata protection features such as optional P2P transaction broadcast and minimal RPC exposure
• Roadmap support for advanced capabilities: zero-knowledge recovery, post-quantum signatures, hardware wallet interoperability

Programming Language: TypeScript.
