Thank you for your feedback. I understand that there are several challenges in implementing the Proof of Random Fairness principle in a blockchain system, such as selecting high-quality validators and creating incentives for nodes to participate. However, this concept aims to reduce the power of any single group that could control validator selection. Designing a system that is fair and transparent will create opportunities for everyone to participate in the network equally and sustainably. I believe that finding solutions to these challenges will allow the system to evolve in a positive direction.
