Explaining SNARKs Part IV: How to make Blind Evaluation of Polynomials Verifiable
<< Part III In this part, we build on Part II and III to develop a protocol for verifiable blind evaluation of polynomials, which we will define shortly. In Part

Bellman: zk-SNARKs in Rust
Bellman is a Rust-language library for building zk-SNARKs — small, cheap-to-verify zero-knowledge proofs of arbitrary computations. The goal of bellman is to make it easier for the general public to

Explaining SNARKs Part III: The Knowledge of Coefficient Test and Assumption
<< Part II In Part II, we saw how Alice can blindly evaluate the hiding :math:`E(P(s))` of her polynomial :math:`P` of degree :math:`d`, at a point :math:`s` belonging to Bob.

Explaining SNARKs Part I: Homomorphic Hidings
Constructions of zk-SNARKs involve a careful combination of several ingredients; fully understanding how these ingredients all work together can take a while. If I had to choose one ingredient whose
