Montgomery Multiplication

Many algorithms in number theory, like prime testing or integer factorization, and in cryptography, like RSA, require lots of operations modulo a large number. The Montgomery (modular) multiplication is a method that allows computing such multiplications faster. Instead of dividing the product and subtracting n multiple times, it adds multiples of n to cancel out the lower bits and then just discards the lower bits.

HyperNova: Recursive arguments for customizable constraint systems

The paper is now updated. The newly added content highlights a new use of folding schemes. Previously, folding schemes were used to construct IVC. We now show that certain folding schemes (e.g., Nova's) unlock a new approach to add ZK in proof systems.

Sparsity-Aware Protocol for ZK-friendly ML Models: Shedding Lights on Practical ZKML

Dong Mo 博士团队新做的一个 ZKML 的工作。主要讲的是通过 ternary network 可以将神经网络模型 （LLM 之类）无损压缩和整数化，并且在这种简化的基础上面设计了一个叫 SpaGKR 的 ZK 算法，实现高效 ZKML inference。目前初步测下来能做到 100X 以上的速度提升，之后会补实验部分。
