KZG Commitment

Properties of KZG:

Trusted setup 🙁
Pairings
constant sized Polynomial 🙂

Trusted Setup

To commit to degree \(\leq l\) polynomials, we need to construct Structured Reference Strings: \( (g, g^\tau, g^{\tau^2} , …, g^{\tau^l})=(g^{\tau^i})_{i\in [0,l]}\)

Note 1: The trapdoor \(\tau\) is generated by distributed protocols, for instance, ….

Note 2: …

From Arithmetic Circuit to Quadratic Arithmetic Programs

Definition of Arithmetic Circuit

Let \(C: \ \mathbb{F}^n \ \rightarrow \ \mathbb{F}^k\) be a map which takes \(n\) arguments from a finite field \(\mathbb{F}\) as inputs and compute \(k\) outputs in \(\mathbb{F}\). \(C\) is an arithmetic circuit if the outputs are determined by the operations \(+\) and \(\times\) to the
