Chainlink tap into gaming with VRF (Verifiable Random Function) technology that went live earlier today on the Ethereum network.
VRF is a highly secure and provably fair source of on-chain randomness for all kinds of blockchain-based applications, NFTs, and games.
On May 23, 2020, The Six Dragons, a Multiverse Game powered by the Enjin ecosystem, became one of the first projects to integrate the VRF technology. It’s important to mention that The Six Dragons is a hybrid game, meaning that enchanting and crafting takes place on centralized servers. Using the Chainlink VRF technology, TSD ensures the randomness in statics for the newly minted in-game items and builds a trust layer between the game and the players.
Verifiable Randomness
Random Number Generation (RNG) is a mechanism for unpredictability. RNG secures the outcome against reverse engineering. However, it’s vulnerable to miner attacks, and it requires complete trust in the data provider when it comes to off-chain implementation.
Chainlink VRF is explicitly designed to support smart contracts’ needs, providing them with an open-source and easily integrated RNG solution directly auditable on-chain by any user via cryptographic proofs.
With this technology, even the oracle provider or the project developers can’t tamper the outcome.
Some Chainlink VRF use cases.
- Non Fungible Tokens (NFTs) – truly randomness with seeding particular collectible traits, loot boxes and any other digital asset that needs to be tamper-proof.
- Random Gameplay Elements – verifiable critical hit points, matchmaking, random encounters, and map generation.
- Ordering for processes – distributing tickets to high-demand events, selecting participants in a popular public sale, and choosing presale winners for luxury items like rare shoes
- Random selection of someone – selecting validator for consensus, drawing a lottery winner, or picking processes within a protocol or a DAO.
When it comes to gaming, Chainlink has many educational articles, such as 16 Ways to Create Dynamic Non-Fungible Tokens (NFT) Using Chainlink Oracles and The Economic Impact of Random Rewards in Blockchain Video Games. You can also check out the extended documentation.
