Figure 6: Random number generation technology using VRF
* NFTs often incorporate rarity, with random selection being the predominant approach. However, this process may present opportunities for intentional adjustments by the project team. To mitigate this possibility, we employ Oracles to implement our Random Number Generation (RNG) technology.
* This technical solution aligns with our core value of friendship and serves as a means of expressing respect for our community. By ensuring that our RNG technology is immune to arbitrary manipulation with VRF, we demonstrate our commitment to fairness and transparency.
