Tentacular NFT Integrates Chainlink VRF to Help Power Provably Fair Berry Juicer Game

We’re excited to announce that Tentacular, a utility-enabled NFT collection, has integrated Chainlink Verifiable Random Function (VRF) on Ethereum mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to help randomly select winners in the Tentacular Berry Juicer game. Ultimately this creates a more exciting and transparent user experience, as users can rest assured that winners are selected in a truly random manner.

Tentacular is a utility-enabled NFT collection of 5,556 Planet Berrylius citizens who have escaped and are now migrating to the Ethereum blockchain. As an adopter of the Tentacular, you get access to the Tentacular ecosystem.

Farm daily berries and use them in the Tentacular Berry Juicer game — a game that mixes chance and strategy for maximum excitement. Organize your farm, save up your berries, and calculate your Juice Squeeze entries. Enter every day, or strike all at once. The choice is up to you.

With rich visual data, the Berry Juicing grounds are ripe for strategic gameplay and giving players the chance to make it big in the Daily, Weekly, Monthly, and Yearly Juice Squeezes. Will the heavy berry farmers dominate the prize pools or will true randomness take its course? Everyone stands a chance to make it big, every day.

In order to help ensure that Juice Squeeze winners are truly selected at random, we needed access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof about the integrity of the process.

After reviewing various solutions, we selected Chainlink VRF because it’s based on cutting-edge academic research, supported by a time-tested oracle network, and secured through the generation and on-chain verification of cryptographic proofs that prove the integrity of each random number supplied to smart contracts.

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 Tentacular smart contract 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 provides our users with automated and verifiable assurances directly on-chain that Berry Juicer reward distributions are provably fair and were not tampered with by the oracle, outside entities, or the Tentacular team.

About Chainlink

Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
