This EIP introduces a new precompiled contract which implements the hash function used in the Poseidon cryptographic hashing algorithm, for the purpose of allowing interoperability between the EVM and ZK / Validity rollups, as well as introducing more flexible cryptographic hash primitives to the EVM.
