Add VIP: VRF integration on VechainThor

Hi all,
This VIP aims to see a VRF (Verifiable Random Function) implementation both at protocol or built-in level. VRF would open the doors for a whole new set of applications and use cases on vechain, also unlocking new reward mechanism for VeBetterDAO apps

Some of the use cases to be unlocked with a VRF:

  • Gaming Applications
    • Lotteries: Fair and transparent random selection of winners.
    • Arcade Games: Securely powering random spins, rolls, or draws.
  • NFT Ecosystem
    • Randomized trait assignment during minting.
    • Introducing unpredictability to NFT drops or airdrops.
  • Gamified Platforms (e.g., VeBetterDAO)
    • Engaging challenges with randomly assigned tasks, multipliers, or rewards.
    • Transparent reward distribution in competitions or leaderboards.
  • Governance Mechanisms
    • Fairly selecting committee members or resolving disputes via random processes.
