OVR.ai is saying a reside and ongoing integration with Chainlink, the marketing-leading decentralized oracle community that gives sensible contracts with safe and dependable off-chain information and computation. The present integration includes the usage of Chainlink Verifiable Randomness Function (VRF) to pretty and transparently choose a particular grant fund winner from the record of individuals collaborating within the upcoming OVRLand Treasure Hunt. Moreover, the OVR workforce plans to leverage Chainlink oracles all through the platform to attach the bodily world to OVRLand’s digital metaverse, enabling a digital expertise that’s impacted by the actual world.
OVR is a decentralized platform for geolocalized Augmented Actuality (AR) / Digital Actuality (VR) experiences, with a imaginative and prescient to merge the bodily and the digital world by means of AR. OVR permits customers to construct, host, and visualize AR/VR experiences which might be custom-made to particular geographic places.
That is completed by OVR dividing the digital world into 300 sqm hexagons known as OVRLands, which every symbolize precise bodily geographic places. Every OVRLand is tokenized utilizing the ERC-721 NFT normal on the Ethereum blockchain. The proprietor of every OVRLand NFT can assign the AR visible expertise for the precise geographic location that their NFT represents.
However what if you happen to might embed decentralized logic into OVRLand NFTs? What if you happen to might take off-chain/geographic information and apply it to the blockchain to supercharge interactions inside the OVR decentralized metaverse?
Right here is the place Chainlink involves play, permitting OVR to securely and reliably join real-world occasions to blockchains as a way to set off sensible contract executions. Knowledge comparable to randomness, geolocation, climate, and extra can all be fetched from off-chain sources and equipped on-chain by way of Chainlink-powered decentralized oracle networks.
Probably the most fast use case for OVR is leveraging randomness to find out metaverse occasions. Nevertheless, the supply of randomness should comprise excessive assurances that it might probably’t be manipulated or predicted to achieve unfair benefits, particularly when the randomness is liable for the motion of actual financial worth. For this reason the OVR workforce chosen Chainlink VRF to find out the winner of our 15okay OVR token closing extraction prize, which serves as a group reward to treasure hunters and to take part in our wider 50okay grant for OVRL and consumers. The extraction course of will probably be completed by means of a public and deterministic algorithm that can iterate by means of the ordered record of OVRLand IDs, with Chainlink VRF used to generate and provide the random quantity used to pretty and transparently choose a winner from the record.
Chainlink VRF works by combining block information that’s nonetheless unknown when the request is made with the oracle node’s pre-committed personal key to generate each a random quantity and a cryptographic proof. The OVR sensible contract will solely settle for the random quantity enter if it has a legitimate cryptographic proof, and the cryptographic proof can solely be generated if the VRF course of is tamper-proof. This supplies customers with automated and publicly verifiable assurances immediately on-chain that choice utilizing Chainlink VRF is provably truthful and can’t be tampered with or predicted by the oracle, exterior entities, or the OVR.ai workforce.
Sooner or later, the OVR workforce additionally anticipates utilizing quite a lot of Chainlink Knowledge Feeds past VRF. Let’s break down some concrete examples on how Chainlink Knowledge Feeds can supercharge blockchain metaverses and OVR.
Think about having AR/VR experiences that aren’t solely geolocalized but in addition “conscious” of actual world situations:
- AR recreation logic modified by the results of a soccer match or an election
- AR location info modified by climate situations
- AR in-game tokens unlocked if a threshold quantity of individuals are current in a location
- AR/VR experiences unlocked if an artist wins a Grammy award
However these are only a few examples—any actual world information supply that may be streamed with an API will be reliably delivered on-chain by Chainlink oracles. The information will be built-in in sensible contracts to create infinite varieties of interplay logic inside the OVR metaverse—creativeness is the one restrict!
In accordance with OVR.ai CEO Davide Cuttini, “Utilizing Chainlink VRF for truthful choice within the OVRLand distribution occasion is just step one in a a lot wider set of Chainlink-OVR integration potentialities that may redefine the whole AR/VR trade. We’re excited to showcase the potential of mixing dependable off-chain information with decentralized metaverses to create vibrant and interactive digital worlds that customers can belief to perform as meant.”
