There is active research going on to construct Lattice cryptography based VRF. Muhammed F. Esgin and others have proposed a practical implementation of Lattice based VRF. In this method, The secret key is constructed a short vector. Fiat-Shamir Heuristics with Aborts technique is used to prove the knowledge of the secret key. What are the key steps in realising Lattice based Verifiable Random Functions efficiently?
