## Note on Language
|
|
|
|
We use slightly different language than others to describe PLONK concepts. Here's the
|
|
overview:
|
|
|
|
1. We like to think of PLONK-like arguments as tables, where each column corresponds to a
|
|
"wire". We refer to entries in this table as "cells".
|
|
2. We like to call "selector polynomials" and so on "fixed columns" instead. We then refer
|
|
specifically to a "selector constraint" when a cell in a fixed column is being used to
|
|
control whether a particular constraint is enabled in that row.
|
|
3. We call the other polynomials "advice columns" usually, when they're populated by the
|
|
prover.
|
|
4. We use the term "rule" to refer to a "gate" like
|
|
$$A(X) \cdot q_A(X) + B(X) \cdot q_B(X) + A(X) \cdot B(X) \cdot q_M(X) + C(X) \cdot q_C(X) = 0.$$

- TODO: Check how consistent we are with this, and update the code and docs to match.
