Represents the field extension constructed as described here. The interface does not provide the full requirements to be a field (like the addition).

Elliptic curve built over the field Fq and the equation y^2 = x^3 + 4

Elliptic curve built over the field Fq^2 and the equation y^2 = x^3 + 4(u + 1)

Prime subgroup of Fq12, of order Fr.order, represented additively

Provides routines to compute the pairing over G1 x G2 -> GT

Implementation of an instantiation of Poseidon over the scalar field of BLS12-381 for a security of 128 bits and with the permutation x^5. The parameters of the instantiation are:

Implementation of an instantiation of Rescue over the scalar field of BLS12-381 for a security of 128 bits and with the permutation x^5. The parameters of the instantiation are:

Return true if the environment variable `BLST_PORTABLE` was set when building the library, otherwise false. Can be used to detect if the backend blst has been optimised with ADX on ADX-supported platforms.
