Key takeaways
Binance Oracle VRF is a verifiable random function (VRF) solution that allows developers on the blockchain to generate random numbers.
Binance Oracle VRF has various use cases, such as GameFi projects and other blockchain products built using smart contracts.
Read on to learn more about how VRFs work, discover why blockchain applications need randomness, and learn how Binance Oracle VRF can benefit your project or business.
Here's everything you need to know about Binance Oracle VRF, the new product powered by Binance Cloud that uses the latest Verifiable Random Function (VRF) standard.
What is a verifiable random function (VRF)?
Verifiable random functions (VRFs) are random number generators (RNGs) whose randomness of results can be cryptographically proven. Here's how they work, in brief:
Multiple inputs are sent to a VRF.
The VRF calculates the inputs and generates pseudo-random results.
Anyone can verify that the results are random at any time using cryptography.
All evidence is published and verified on the blockchain before applications are allowed to use the results.
Why do blockchains need random numbers?
Blockchain applications should use random numbers in several situations, including:
Design of a game on the blockchain.
Distribution of tasks and resources.
Choice of samples for a consensus mechanism.
To illustrate our point, let's now see how chance can help a GameFi developer create a poker game on the blockchain.
The developer must convince his or her users that the algorithm of his or her poker game is fair and impartial. For example, cards are shuffled at random intervals, and no party, including the developer, can interfere in the game.
Rather than using a black box algorithm that hides the inner workings of the game from players, developers on the blockchain can effectively prove the randomness of their product by showing how the numbers are generated by a data provider. 'reliable oracle. Users are thus certain that their game is fair and impartial.
Generating chance: a real challenge
A good random number result must meet four criteria: impartiality, unpredictability, verifiability and instant availability.
Many blockchain developers face difficulties when producing random numbers on the blockchain in their application, due to the deterministic nature of the blockchain: often, the randomness generated on the blockchain is not sufficiently unpredictable.
On the other hand, relying solely on an oracle provider outside the blockchain could force developers to ignore the availability, or worse yet, the security of their creation. In some contexts, if a malicious provider transmits predictable randomness, bad actors can take advantage of the situation to ensure they receive a favorable outcome. Imagine a game focused on obtaining loot, where players can try to open a treasure chest several times until they reach the desired object, or a card game where they can draw several cards until they find the most advantageous one for them.
The workings of VRFs
The VRF combines these two independent sources to generate figures. The randomness of the numbers generated by the provider outside the blockchain thanks to its private key comes from the two block hash parameters and preSeed. These two parameters guarantee the unpredictability of the proof, since it is impossible to predict the block hash until the block is generated.
Proof provided off-blockchain ensures that the random number is generated through block hashing and preSeed, and is not the creation of a malicious provider. The random nature of the result is thus verifiable.
Simply put, developers can generate random numbers securely and impartially.
