Apologies if you’ve already answered these, but the information is a bit dense, and I have a few questions to help me put this work into context… Say, practical takeaways.
Could one use case for this be to help people in developing nations receive small amounts of bitcoin instantly and with low transaction fees? I suppose the question is, can this work well for small payments as well as for large ones?
Additionally, how critical is liveness for trustlessness? Could this work on a mobile app for example?
What are the worst case scenarios, especially if the LSP is shut down by the authorities?
How much do you think this can scale with 1MB blocks? Does this essentially solve the billions of Lightning users metric without the need for changes to bitcoin?
Finally, are there any implementations underway? Could this be compatible with LND or CLN, say as a plugin or layer, or would an entire new node be needed, such as one built with LDK?
