Non-Arithmetic Operations

Definition

Non-arithmetic operations refer to computational steps within a program or circuit that do not primarily involve standard addition or multiplication, such as comparisons, bitwise operations, or memory access. When converting a program into an arithmetic circuit for zero-knowledge proofs, these operations often present a challenge, requiring more complex and resource-intensive arithmetization. Efficiently handling non-arithmetic components is a significant area of research to improve the practicality of verifiable computation. Their efficient representation directly impacts proof size.
