Powered by Binance Cloud and based on the latest Verifiable Random Function (VRF) standard, here’s everything you need to know about Binance Oracle VRF.

What is a Verifiable Random Function (VRF)?

Verifiable random functions (VRFs) are random number generators (RNGs) whose outputs can be cryptographically proven to be random. Here’s a quick summary of how it works.

1. A number of inputs are fed into a VRF.
2. VRF calculates the inputs and generates pseudorandom outputs.
3. Anyone, at any time, can cryptographically verify that the output is random.
4. All proofs are published and verified on-chain before applications can use the output.

Why do blockchains need random numbers?

There are various scenarios where blockchain applications require randomness. A few examples include:

• Building a blockchain-based game.
• Allocation of tasks and resources.
• Pick samples for a consensus mechanism.

To illustrate, let’s examine how randomness can help a GameFi developer build a blockchain-based poker game.

The developer must convince the users that the poker game uses a fair and objective algorithm. For example, the deck is shuffled randomly, and no party, including the developer, can manipulate the game.

Instead of using a black box algorithm that hides the game’s inner workings from users, blockchain developers can effectively prove randomness by showing how their numbers are generated through a trusted oracle provider. This way, users can be sure that their game is fair and unbiased.

The challenge of generating randomness

When generating randomness, a good output must meet four criteria: objective, unpredictable, verifiable, and immediately available.

Many blockchain developers find it challenging to produce on-chain randomness in their applications due to the deterministic nature of blockchain. The randomness generated on the chain usually cannot satisfy the unpredictability.

On the other hand, relying only on a single off-chain oracle provider can force developers to compromise availability or, worse, security. In certain contexts, if a malicious supplier feeds some predictable randomness, bad actors can exploit the situation to ensure that they get a favorable outcome. Imagine a swap-based game where players can try to open a treasure chest multiple times until they get an item they’re happy with. Or a card game where players can draw their hands several times until they get a good one.

What’s under the hood

VRF combines these two independent sources of seed generation. The randomness constructed by the off-chain provider with its private key is generated from the two parameters block-hash and preSeed. This ensures the unpredictability of the proof, as you cannot predict the block hash until the block is generated.

The proof provided off-chain ensures that the randomness is generated from the block hash and preSeed rather than something that a malicious vendor could invent. That makes this coincidence verifiable.

Simply put, developers can generate random numbers fairly and securely.
