According to Foresight News: Ola, a programmable privacy and scalability solution, has recently integrated the Poseidon2 hash into its proof system, resulting in over a 40% improvement in prover performance compared to the original Poseidon hash.

Poseidon2 is a new hash algorithm that maintains the same level of security as Poseidon hash while offering better zk-friendly features. Ola's proof system includes several zk-friendly hash algorithms, such as private state tree, public state tree, signature verification process, and plonky2 recursive process.

Ola announced that its zkVM testnet is set to launch in early Q4 this year, with more development details to be revealed soon.
