What is Band VRF ?
Randomness is a fundamental function that helps to operate many decentralized applications (dApps). However, the root and foundation of this vital randomness mechanism is often neglected. Band’s VRF service addresses the fundamental issues that threaten the integrity of various Web3 use-cases by providing a pseudorandom output along with the proof of authenticity that validates the random number generation process.
Key Features
Unpredictability
Ensure it is impossible to predict randomness to increase the odds of success because the seed is unknown ahead of time. A VRF provider is randomly selected to add another layer of unpredictability.
Unbiased
Uniform distribution, therefore, all numbers in the range have an equal chance of being selected.
Verifiable
The result can't come out of thin air, it holds transparency and is verifiable after it has emerged.
Tamper-Proof
Not a single person or entity can tamper with the RNG process

How does Band VRF work?
Band Protocol's solution for verifiable pseudorandomness is based on the BandChain blockchain. Our protocol uses a Verifiable Random Function (VRF) to cryptographically secure and verify that output results have not and cannot be tampered with.
Similar to the BandChain Oracle Network, the BandChain Verifiable Randomness is a VRF system that serves requests from dApps. Validators on the BandChain and the VRF Oracle Script are responsible for generating the random number requests that are verifiably random. Final validated results are stored on the BandChain as proof of the random number generation process before returning the results to the requested dApps.
