zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

is a manufacturer of industrial-grade unit
heaters suitable for hazardous and severe-duty locations.
The Hydronic Unit Heater (HUH2) series of heat-
exchanger unit heaters were specifically designed to meet
the demanding requirements of the oil & gas industry. The
operating conditions of this industry require heating equip-
ment that is safe, reliable, dependable, and available
when you need it. The rugged design features of the HUH2
series also makes it ideal for use in other heavy-duty
industries that include pulp & paper, power generation, mining, steel mills, foundries, water and
wastewater treatment plants, chemical plants, and hazardous material storage facilities.
