What is a Verifiable Random Function (VRF)?
A verifiable random function (VRF) is a random number generator (RNG) whose output can be cryptographically proven to be random. The mechanism can be briefly summarized as follows.
- A series of inputs are passed to the VRF.
- VRF computes the inputs and generates pseudo-random outputs.
- The fact that the output is random can be cryptographically verified by anyone, at any time.
- All proofs are published and verified on-chain before the application uses the output.
Why do we need random numbers on the blockchain?
There are many different scenarios where blockchain applications need randomness. Some examples are.
- Create a blockchain-based game
- Assign tasks and resources.
- Pick a sample for a consensus mechanism.
For illustration purposes, let’s examine how randomness can help GameFi developers build blockchain-based poker games.
The developer must convince users that the poker game uses a fair and unbiased algorithm. For example, the deck of cards is shuffled randomly and no party, including the developer, can manipulate the game.
Blockchain developers can effectively prove randomness by showing how the numbers are generated through a trusted oracle provider, rather than using a black box algorithm that hides the internal structure of the game from the user. This way, users can be assured that their game is fair and unbiased.
Challenges to Randomness Generation
When generating randomness, a good output must satisfy four conditions: unbiased, unpredictable, verifiable, and instantly available.
Many blockchain developers find it difficult to generate on-chain randomness in their applications due to the deterministic nature of blockchain. On-chain generated randomness usually cannot satisfy unpredictability.
On the other hand, relying on a simple off-chain oracle provider may force developers to compromise on availability or, even worse, security. In some contexts, malicious
