Number Theoretic Transform: a discrete Fourier transform over a finite field, enabling fast polynomial multiplication in stark proof systems over the goldilocks field
NTT replaces complex roots of unity with primitive roots in a prime field, achieving O(n log n) polynomial multiplication with exact integer arithmetic
in cyber, NTT is a core operation in STARK proof generation, where large polynomial evaluations and interpolations dominate computation cost
efficient NTT implementations exploit the structure of Mersenne primes and goldilocks field primes to maximize hardware parallelism
