KZG Polynomial Commitment
KZG stands for Kate-Zaverucha-Goldberg. It is a non-transparent polynomial commitment scheme that requires a trusted setup. It uses pairings and polynomial commitments to deterministically check the validity of a degree d polynomial using d queries. KZG can achieve very succinct proofs, but at the cost of higher prover time and interactive verification.
KZG commitment has 4 different steps:
This was a brief overview of the mathematical concepts involved in KZG, with some specifics omitted [2,3].
