Detailed Description

template<typename Params>
class bb::crypto::Poseidon2< Params >

Native Poseidon2 hash function implementation.

This implementation is differentially tested against the stdlib (circuit) implementation. The stdlib tests (stdlib/hash/poseidon2/poseidon2.test.cpp) validate both implementations against independent test vectors from https://github.com/zemse/poseidon2-evm and verify that native and circuit implementations produce identical outputs.
