Caveworld to Integrate Chainlink Tools to Increase Transparency and User-Friendliness

5 min readFeb 23, 2022


We’re thrilled to announce that Caveworld, the most exciting Play-to-Earn battle game on Solana, is integrating Chainlink Price Feeds and Chainlink Verifiable Random Function (VRF) to help provide players with user-friendly experiences defined by transparency and fairness as they navigate the Caveworld game. Built in Unreal Engine, Caveworld is one of Solana’s largest upcoming metaverse opportunities, allowing players to explore, battle, level up, and earn rewards all along the way. The more you play, the more you earn! Although owners of Crypto Cavemen NFTs will receive the largest rewards inside the game, players around the globe can enter the ecosystem using game passes or by owning partnered NFTs.

Why Chainlink VRF?

Chainlink is the industry-leading decentralized oracle network specializing in providing off-chain data and computation services to smart contracts.

When it came time to determine how we would run our random number generation for choosing battle opponents, NFT reward distributions, and more, Chainlink VRF was an obvious choice for us. Based on cutting-edge blockchain technology, and supported by time-tested infrastructure, this tamper-proof and auditable on-chain RNG solution will help ensure users remain comfortable with all in-game outcomes.

How does it work?

Chainlink VRF works by combining block data, unknown at the time of the request, with the oracle node’s private key, to generate a random number with cryptographic proof. When Caveworld’s smart contract interacts with Chainlink VRF, it will not only ensure that all in-game outcomes use tamper-proof random numbers but will also require verifiable proof. If either one of those conditions are not met, the request will not be met. This means players can have complete assurance that no external bodies — whether users, players, or the Caveworld team — can manipulate the random number generation process.

Why Chainlink Price Feeds?

As Caveworld is denominated with CAVE coin, the Cavemen’s sole currency, we knew it was important for price feeds to be highly reliable and timely. Users should have access to accurate token prices, especially given the many exchanges and marketplaces spread throughout the ecosystem. Chainlink Price Feeds solve this issue by providing a blockchain oracle solution to continuously fetch off-chain price data and deliver it to smart contracts for the benefit of players.

Chainlink Price Feeds will be increasingly important for Caveworld by helping power future NFT marketplace price display and transaction processing functions. We chose to use Chainlink because they have a proven history of reliably delivering accurate price data on-chain. The professional DevOps teams running Chainlink oracle nodes have already delivered 2B+ data points on-chain and currently help secure tens of billions of dollars in value. This time-tested oracle infrastructure is ideal for Caveworld as it continues to grow.

Chainlink Price Feeds have superior features when compared to other solutions, such as:

  • High-Quality Data — Chainlink Price Feeds source data from numerous premium data aggregators, leading to price data that’s aggregated from hundreds of exchanges, weighted by volume, and cleaned from outliers and suspicious volumes. Chainlink’s data aggregation model generates more precise global market prices that are resistant to API downtime, flash crash outliers, and data manipulation attacks like flash loans.
  • Secure Node Operators — Chainlink Price Feeds are secured by independent, security-reviewed, and Sybil-resistant oracle nodes run by leading blockchain DevOps teams, data providers, and traditional enterprises with a strong track record for reliability, even during high gas prices and extreme network congestion.
  • Decentralized Network — Chainlink Price Feeds are decentralized at the data source, oracle node, and oracle network levels, generating strong protections against downtime and tampering by either the data provider or the oracle network.
  • Transparency — Chainlink provides a robust reputation framework and set of on-chain monitoring tools that allow users to independently verify the historical performance of node operators and oracle networks, as well as check the real-time prices being offered.

“Chainlink is the gold standard for decentralized oracle networks in the blockchain ecosystem, and Caveworld settles for nothing less than the best. When it came to providing our users with a seamless gaming experience built upon the core values of transparency and fairness, Chainlink was the obvious choice for random number generation and price data feeds.” — Caveworld Team

More About Caveworld

Caveworld provides traditional gamers and Web3 enthusiasts around the globe an opportunity to be the beneficiaries of their gaming success. In this Play-To-Earn world, players collect rewards as they level-up. These rewards, given in the form of an NFT item, can allow players to upgrade other items, or can be traded in the marketplace for our native token, CAVE. The higher your level, the rarer the rewards you get become. Meaning, the more effort you input, the greater the output of rewards. In addition to this Play-to-Earn mechanic, Caveworld has a plethora of other in-game mechanics, such as Tribes, that acts as a referral system for players to recruit their friends, family, and colleagues. The goal of this system is to provide the tribe leaders, called chiefs, a piece of all of the rewards earned by the members. This mechanic, however, is reserved solely for holders of Crypto Cavemen NFTs. Read more about Caveworld here!
