Low-degree polynomial extension: using the above polynomial constraints, we can obtain a computation trace polynomial of length uts * N. For security reasons, we perform commitment to the polynomial on a larger evaluation domain, with the domain amplification factor as extension_factor. In the above case, we could calculate a polynomial p(x) from I(x). When we use an extension_factor of 8, we will calculate another 32(8-1)* points on p(x).Published on 10 May 2023Updated on 8 Sept 2025FAQ179Lead traders: Spot lead trading guidelines
