ePrint Report: Poseidon2: A Faster Version of the Poseidon Hash Function

Lorenzo Grassi, Dmitry Khovratovich, Markus Schofnegger

Zero-knowledge proof systems for computational integrity have seen a rise in popularity in the last couple of years. One of the results of this development is the ongoing effort in designing so-called arithmetization-friendly hash functions in order to make these proofs more efficient. One of these new hash functions, Poseidon, is extensively used in this context, also thanks to being one of the …
