Definition ∞ zkML arithmetization is the process of converting a machine learning model’s computations into an arithmetic circuit, which can then be proven using zero-knowledge proofs. This transformation allows for verifiable execution of AI models, meaning one can cryptographically confirm that a model was run correctly on specific inputs without revealing the model itself or the inputs. It is a crucial step for privacy-preserving and auditable artificial intelligence.
Context ∞ The field of zkML arithmetization is a rapidly developing area at the intersection of zero-knowledge proofs and machine learning, with news often highlighting its potential for verifiable AI on blockchains. This technique is central to enabling confidential inferences, secure data sharing for model training, and provably fair AI systems. Current research focuses on optimizing the arithmetization process to reduce the computational cost and proof size, making it practical for real-world applications.
