As a motivated and promising project, Kephi Gallery is excited to announce our integration of industry-leading oracle network Chainlink. Kephi Gallery has integrated two Chainlink oracle services: Chainlink VRF for a verifiably tamper-proof randomness and Chainlink Price Feeds for accurate and secure cryptocurrency exchange rates.

By integrating these Chanlink-powered solutions, Kephi Gallery ($KPHI) users can now enjoy fairer circulation and stronger security of the $KPHI NFT rewards generation process, as well as more dependable exchange rates when buying and selling NFTs.

Kephi Gallery is a myriad marketplace for visual artists, musicians, short-film creators, theatre performers, and more to gather together and share their work with monetization benefits. Every artist is encouraged to mint their NFT’s and start exchanging their pieces of art utilizing Kephi Gallery services.

Chainlink oracle networks enable smart contracts to access data and computations not inherently available on their native blockchain networks, often referred to as “real-world data’’ or “off-chain resources.” Through Chainlink oracles, blockchains can verify events happening in the outside world, such as the current price of assets, as well as access trust-minimized computations like the generation of random numbers backed by cryptographic proofs.

For Kephi, Chainlink comes in handy for two initial use cases. The first is the ability to distribute random NFT rewards to KPHI stakers in a verifiably fair manner. In Kephi Gallery, users can stake KPHI for a chance to win NFTs from various NFT drops taking place on the platform. By deploying Chainlink VRF, Kephi Gallery can help ensure a random, fair, and secure reward generation process for $KPHI stakers.

We selected Chainlink VRF for randomness generation because it is time-tested and has already secured drops for some of the biggest NFT projects like BAYC. Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. The Kephi Gallery app will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This helps provide our users with automated and verifiable proof directly on-chain that the Kephi Gallery’s NFT distributions are provably fair and were not tampered with by the oracle, outside entities, or the team.

The second integration involves the use of Chainlink Price Feeds, so $KPHI artists can list their NFTs at stable prices and adequately compare their work against the likes of other NFT marketplaces similar to OpenSea or Rarible. Chainlink Price Feeds maintain high-quality, tamper-proof data feeds on blockchains that track a variety of crypto exchange rates. The Price Feeds can then be used to list NFTs in various cryptocurrencies at stable values and then be purchased in real-time in other cryptocurrencies by referencing the real-time exchange rates of Chainlink. Ultimately, this creates more flexibility in how NFTs are listed and purchased, and offers a way to check Kephi Gallery against other NFT marketplaces.

We are excited to integrate these key pieces of Chainlink infrastructure to provide our users with a more seamless and secure experience, and we expect further integrations as our platform develops.

“We decided to integrate Chainlink into Kephi Gallery to establish a more trustworthy, secure, and transparent platform for our users. The Chainlink oracle solutions were seamless to integrate and provided critical infrastructure for our team to build key functionality that users require when creating, minting, and trading NFTs.” — Nicolás Verderosa, Kephi Gallery CEO
