Random Distribution of Quadbikes

In order to distribute the Quadbike NFTs in a provably fair manner, we need 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 of 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.

First, we collected all the COBI NFT Wallets snapshot at 8:00 PM UTC on 2nd May 2022 in the descending order based on the Number of NFTs held
Second, took a snapshot of all the wallets staked a cumulative of 10K $BULL tokens across 3 $BULL Staking Pools. Then, We ordered them in descending order of the number of tokens and added these wallets to the COBI NFT wallets, and removed the duplicates.

List of wallets eligible for Quad Bike Drop.

A Total of 2421 wallets are eligible for Quad Bikes drop.

Quad Bike Rarity Distribution:

Tier 1: 121(5%)

Tier 2: 484 (20%)

Tier 3: 1816 (75%)

Randomly assigning Quad Bikes :

Added all the QuadBikes to a List (Tier1 (5%)+ Tier2(20%) + Tier3(75%))
Off-chain, programmatically shuffled the List using the Fisher-Yates Shuffle algorithm using a random input for a random number of times.
Then the List is passed to the Contract in the above order.
We used Chainlink VRF to generate a random number and applied the transformation to it to generate a random starting index (randomNumber % 2421)
New order of quadbikes is used as input to add the reward for the wallets to claim the respective quadbikes assigned randomly based on above process.

What’s next?

Your Quad Bike NFTs are your ride in the Bullieverse Metaverse. These NFTs will also help you in the Bullieverse ecosystem with utility in games and Metaverse over the next few months. Watch this space!
