An arithmetic circuit is a computational model that performs mathematical operations on inputs. In cryptography, it represents a sequence of addition and multiplication gates used to define a computation for zero-knowledge proofs. These circuits transform a computational problem into a form verifiable without revealing the inputs themselves. Their structure is fundamental for proving the correctness of complex calculations privately.
