Golden Finance reported that the StarkNet ecological project Pragma announced the launch of the first phase of the Verifiable Random Function (VRF) in Cairo 1. Pragma VRF will help numerous smart contracts on Starknet, especially those that need to prove that they use external, unchangeable random sources. The first phase involves publishing the randomness proof as call data so that anyone can verify it off-chain. The second phase is coming soon, which will directly implement the verification of the proof on the chain. Users who request VRF need to bear the gas cost of their callback function and the symbolic fee of the randomness request.
