Greetings my friend @simonnwigwe, I hope you are fine.

You have given a perfect example of physical and spiritual worlds. The oracles is the same as there is one outside world that we can touch like real world information and second is virtual world that is of blockchain that we can't touch but it is just like a real world.

Blockchain oracles play intermediate role in between two worlds to transfer information from one to another which was not possible before.

You have explained different types of oracles that include software, hardware, centralized, decentralized, inbound, outbound, and bi-directional oracles. I am reading bi-directional type for the first time.

This is the reason why I look taking part in these contest is because I will learn new things from other Steemians as well.

You have also share your view on decentralized oracles and use cases of it the include NFTs, DeFi, Insurance, and Cross chain service.

Overall, you have presented quality content with us. It shows how much effort you put in creating content. Thank you for sharing it with us. I learned from it.

I wish you success in this contest dear friend 💕💕
