The main point
Binance Oracle's VRF is a Verifiable Random Function (VRF) solution that allows blockchain developers to generate random numbers.
Binance Oracle's VRF can be used for a wide range of uses, including GameFi projects and other blockchain products built on smart contracts.
Read on to learn more about how VRF works, why blockchain applications require randomness, and how Binance Oracle VRF can benefit your project or business.
Powered by Binance Cloud and based on the latest Verifiable Random Function (VRF) standards, here's everything you need to know about Binance Oracle VRF.
Apa itu Verifiable Random Function (VRF)?
Verifiable Random Functions (VRF) are random number generators (RNG) whose output can be cryptographically proven to be random. Here's a quick summary of how it works.
A series of inputs are passed into the VRF.
VRF computes the input and produces a pseudorandom output.
Anyone, at any time, can cryptographically verify that the output is random.
All proof is published and verified on-chain before applications can use the output.
Why Does Blockchain Need Random Numbers?
There are various scenarios where blockchain applications require randomness. Some examples include:
Creating blockchain-based games.
Allocate tasks and resources.
Selecting samples for the consensus mechanism.
To illustrate, let's look at how randomness works which can help GameFi developers create blockchain-based poker games.
Developers must assure their users that poker games use fair and unbiased algorithms. For example, a deck of cards is shuffled randomly and no party, including the developer, can manipulate the game.
Rather than using black box algorithms that hide how the game works from its users, blockchain developers can effectively prove randomness by showing that the numbers were generated through a trusted oracle provider. This way, users can be sure that the games they are playing are fair and unbiased.
Challenges in Generating Randomness
When generating randomness, a good output must meet four criteria: unbiased, unpredictable, verifiable, and instantly available.
Many blockchain developers find it difficult to create on-chain randomness in their applications due to the deterministic nature of blockchain. Randomness generated on-chain usually cannot satisfy the nature of uncertainty.
On the other hand, relying solely on regular off-chain oracle providers can force developers to sacrifice availability or, worse, security. In certain contexts, if a malicious provider provides predictable randomness, malicious actors can exploit the situation to ensure they receive profitable outcomes. Imagine a loot-based game that allows players to open treasure chests multiple times until they get the item they like. Or, a card game that allows players to draw cards many times until they get a good card.
Components Behind It
VRF combines these two independent sources to produce a seed. The randomness created by the off-chain provider with the private key is generated from the two parameters block hash and preSeed. This ensures an unpredictable proof, as you cannot predict the block hash until the block is generated.
Proof provided off-chain ensures that randomness is generated from the block hash and preSeed, not something that can be created by a rogue provider. This makes randomness verifiable.
Simply put, developers can generate random numbers fairly and safely.
