KZG Schemes

Definition

KZG schemes, named after Kate, Zaverucha, and Goldberg, are a type of polynomial commitment scheme used in advanced cryptographic proofs, particularly zero-knowledge proofs. These schemes allow a prover to commit to a polynomial without revealing its coefficients and later prove evaluations of that polynomial at specific points. KZG commitments offer efficiency and succinctness, making them valuable for scaling blockchain networks and enhancing privacy. They are a critical component in many modern cryptographic protocols.
