# Chainlink [Chainlink](https://chain.link/) is a decentralized blockchain oracle network built on Ethereum, the industry-standard Web3 services platform connecting the people, businesses, and data of today with the Web3 world of tomorrow, and [Chainlink VRF](https://chain.link/vrf) provides cryptographically secure randomness for blockchain-based applications. #### **Chainlink VRF (Verifiable Random Function):** Chainlink VRF is a provably fair and verifiable random number generator (RNG) that enables smart contracts to access random values without compromising security or usability. For each request, Chainlink VRF generates one or more random values and cryptographic proof of how those values were determined. The proof is published and verified on-chain before any consuming applications can use it. This process ensures that results cannot be tampered with or manipulated by any single entity including oracle operators, miners, users, or smart contract developers. {% hint style="success" %} With Chainlink VRF, [Dystolab Crates ](/ecosystem/nft-collections/dystolab-crates.md)are completely anti-cheat and 100% enjoyable! {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
