Simply put, a blockchain is a system of recording information in such a way that it makes it very difficult if not impossible to change, cheat or hack the system. It is basically a digital ledger or record of transactions duplicated and distributed across the entire network of computer systems on the blockchain.
Virtual reality ( more commonly known as VR) is a simulated experience that can be similar to or completely different from reality.
The application of virtual reality include but is not limited to entertainment (video games in particular), business (virtual meetings) and education. The other distinct types of VR-ish technology include augmented reality and mixed reality which is sometimes referred to as extended reality or XR.
