We set out to investigate potential improvements to Lightning on both the protocol level and in how it’s used. With an awareness of current privacy best practices and pitfalls, what else is possible to improve Lightning privacy?We’ve split our findings into three chapters, though there’s obviously a compounding effect to adopting multiple of these techniques, along with pitfalls that can render a whole stack of privacy techniques ineffective. No silver bullets, at least not yet!This research is open source at lightning-privacy-research. Comments, suggestions, fixes, and additional ideas are all welcome.
