Solution: Part 2
Explore how to implement Verifiable Random Function (VRF) in Solidity to handle randomness in a Treasure Hunt play-to-earn game. Understand abstract contracts, inheritance, state variables, and event declarations to manage multi-player random outcomes securely and efficiently.

VRF-related abstract contract
In the following code, we'll define an abstract TreasureHuntVRF.sol contract that contains the setting parameters of the VRF and the aspects of our game that depend on randomness. We don't implement any function in this abstract contract, except for the VRF callback function fulfillRandomWords(), which requires some adjustments for our game. We must mark the contract as abstract because it doesn't implement the VRF constructor. We'll save that for the last ...
