you can fully destroy perfect onchain privacy by leaking metadata (IP, user-agent, timezone, language settings, etc.). using Tor for any onchain interaction is one way but it's very easy to also fingerprint you as Tor user. what Ethereum needs is its own browser that _natively_ embeds Kohaku (as wallet) with the following system invariant: everyone using the same privacy profile (let's call them "Fingerprint Profile") looks exactly the same to websites, because the browser forces all observable behaviour into a small number of _standardised_ (but not Tor-identifieable) patterns. we can only win this if we control the kernel space (i.e. browser) and not only the user space (i.e. extension). also, my current thinking is that a browser is the interface to the internet and if we want to "scale" privacy in some form, a browser is the perfect distribution channel (private OSes will be much harder for example).
