OVR.ai is saying a reside and ongoing integration with Chainlink, the marketing-leading decentralized oracle community that gives good contracts with safe and dependable off-chain information and computation. The present integration entails the use of Chainlink Verifiable Randomness Function (VRF) to pretty and transparently choose a particular grant fund winner from the checklist of members collaborating in the upcoming OVRLand Treasure Hunt. Additionally, the OVR crew plans to leverage Chainlink oracles all through the platform to join 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 Reality (AR) / Virtual Reality (VR) experiences, with a imaginative and prescient to merge the bodily and the digital world via AR. OVR permits customers to build, host, and visualize AR/VR experiences which are custom-made to particular geographic places.
This is completed by OVR dividing the digital world into 300 sqm hexagons referred to as OVRLands, which every signify precise bodily geographic places. Each 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 particular geographic location that their NFT represents.
But what should you may embed decentralized logic into OVRLand NFTs? What should you may take off-chain/geographic information and apply it to the blockchain to supercharge interactions inside the OVR decentralized metaverse?
Here is the place Chainlink comes to play, permitting OVR to securely and reliably join real-world occasions to blockchains so as to set off good contract executions. Data resembling randomness, geolocation, climate, and extra can all be fetched from off-chain sources and provided on-chain through Chainlink-powered decentralized oracle networks.
The most instant use case for OVR is leveraging randomness to decide metaverse occasions. However, the supply of randomness should include excessive assurances that it could’t be manipulated or predicted to achieve unfair benefits, particularly when the randomness is answerable for the motion of actual financial worth. This is why the OVR crew chosen Chainlink VRF to decide the winner of our 15k OVR token ultimate extraction prize, which serves as a neighborhood reward to treasure hunters and to take part in our wider 50k grant for OVRL and patrons. The extraction course of will probably be carried out via a public and deterministic algorithm that may iterate via the ordered checklist of OVRLand IDs, with Chainlink VRF used to generate and provide the random quantity used to pretty and transparently choose a winner from the checklist.
Chainlink VRF works by combining block information that’s nonetheless unknown when the request is made with the oracle node’s pre-committed non-public key to generate each a random quantity and a cryptographic proof. The OVR good contract will solely settle for the random quantity enter if it has a sound cryptographic proof, and the cryptographic proof can solely be generated if the VRF course of is tamper-proof. This offers 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 crew.
In the future, the OVR crew additionally anticipates utilizing quite a lot of Chainlink Data Feeds past VRF. Let’s break down some concrete examples on how Chainlink Data Feeds can supercharge blockchain metaverses and OVR.
Imagine having AR/VR experiences that aren’t solely geolocalized but in addition “aware” of actual world circumstances:
- AR sport logic modified by the results of a soccer match or an election
- AR location info modified by climate circumstances
- 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
But these are just some examples—any actual world information supply that may be streamed with an API might be reliably delivered on-chain by Chainlink oracles. The information might be built-in in good contracts to create infinite forms of interplay logic inside the OVR metaverse—creativeness is the solely restrict!
According to OVR.ai CEO Davide Cuttini, “Using Chainlink VRF for fair selection in the OVRLand distribution event is only the first step in a much wider set of Chainlink-OVR integration possibilities that can redefine the entire AR/VR industry. We are excited to showcase the potential of combining reliable off-chain data with decentralized metaverses to create vibrant and interactive virtual worlds that users can trust to function as intended.”
