I’ve looked at the 2 PDFs in the most recent reply, and it looks like they are actually quite similar to the existing schemes ([1] Minglejingle, [2] LIP-0004, and [3] Non-interactive Mimblewimble transactions, revisited).
@Andi, how does your idea differ from those 3? Are there any notable improvements over these schemes? AFAICT, your writeups each seem to be just minor variations of [2] and [3], but if there is something more novel about your approach that I may have overlooked on my first read, please let me know, and I’d be happy to take another look.
