and I built a folding scheme from (unstructured) lattice assumptions, which will be presented at Asiacrypt this week! (1/8) Lattice folding schemes face two issues: witness norm growth (completeness), and norm growth when extracting (non-relaxed knowledge soundness). We use a split-and-fold technique to get around #1, and we use witness cross-terms (which we also fold) for #2. (2/8)
