On Understanding of the Permutation in Plonk

Question 1:

There are two list \((a_1, a_2, a_3,…a_n)\) and \((b_1,b_2,b_3,…,b_n)\)

how can we prove they contain the same element? (now we only consider to have the same elements, permutation comes in next question) This question would help you to understand why the permutation construction in Plonk is constructed in …

The Short NIZK Argument in Pribank

We give a commit-and-prove zero-knowledge argument Protocol for the satisfiability of a QAP for an arithmetic circuit \(C\). For wires in the circuit \(\{a_i\}_{i=0}^n\), we denote the input witnesses are \(\{a_i\}_{i=0}^k\), the inner circuit witnesses are \(\{a_{i}\}_{i=k+1}^l\) and the statements wires are \(\{a_{i}\}_{i=l+1}^n\). The quadratic arithmetic program, Pedersen commitment and …

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
