Chainlink announced the launch of the verifiable random function (VRF), which generates trusted random numbers in decentralized applications. Now the function is available on the Ethereum blockchain for testing by users of the testnet.
This feature provides an important advantage for decentralized services — game developers will not be able to manipulate the results of certain actions. The result with cryptographic confirmation will be published on the blockchain, where anyone can check it using a public key. The fake value will not pass the verification with the key and as a result gets a monetary penalty.
