Struct halo2_gadgets::poseidon::primitives::P128Pow5T3
source · pub struct P128Pow5T3;
Expand description
Poseidon-128 using the $x^5$ S-box, with a width of 3 field elements, and the standard number of rounds for 128-bit security “with margin”.
The standard specification for this set of parameters (on either of the Pasta fields) uses $R_F = 8, R_P = 56$. This is conveniently an even number of partial rounds, making it easier to construct a Halo 2 circuit.
