e-VRF Use Cases

#1 Randomness Generation

For developers, particularly in the gaming sector, leveraging the secure and verifiable randomness provided by Entangle VRF opens up new possibilities for creating fair and unpredictable game outcomes.

To incorporate e-VRF into applications, here are the steps you can follow:

• Random number request: Users or developers initiate the process by requesting a random number, specifying the desired publication delay through a special contract. This delay determines the specific block that will serve as the reference point for selecting the random number, based on its inclusion in the blockchain post-timer expiry.

• Proof selection and publication: The protocol then identifies a set of unused e-VRF proofs corresponding to the specified block. From this set, a single proof is pseudo-randomly selected to fulfil the user's request. The selection of this proof, and consequently the random number it verifies, is treated as a consumable event, marking the entire set of proofs for that block as utilized.

By integrating e-VRF into their applications, developers can assure users of the integrity of random events, from the distribution of rare in-game items to the outcomes of competitive matches.

#2 Integration with Entangle's Ecosystem

e-VRF seamlessly integrates with Entangle’s Universal Data Feeds and Photon Messaging. This integration supports a wide range of on-chain applications and facilitates cross-chain communication, making e-VRF a versatile tool for developers.

#3 Versatile Utility

e-VRF finds its utility in numerous on-chain scenarios, including but not limited to:

• Gaming: Ensuring fairness and unpredictability in game outcomes.

• NFTs: Generating unique attributes for non-fungible tokens.

• Gambling: Providing transparent and tamper-proof random numbers for betting systems.

• Generative Art: Creating unique, algorithmically generated artworks based on random inputs.

#4 Security

e-VRFs can also be very useful in the security sector, where verifiable randomness is essential. Let’s look at some examples:

• Decentralized networks: VRFs can be used to select validators, generate random assignments, or ensure fair play in decentralized games and lotteries.

• DNS security: VRFs enhance the security of protocols like DNS by providing a secure method to authenticate messages and prevent attacks.

• Zero-knowledge proofs: In systems that rely on zero-knowledge proofs, VRFs can be used to generate random challenges or conditions that need to be satisfied.
