Dear @cinnymartins you have explained very well about blockchain oracles and i just visited your blog and i got so much information from your it's really interesting.Yes brother you're right blockchain oracles act as intermediate between distributed ledger and the real world and the blockchain oracles has been designed to give the answers of the questions that blockchain can't do itself.You explained really good about blockchain oracles and your searched about blockchain oracles is really appreciating.

The most common type of oracle is software, which consists of computer programs that link third-party data sources to the blockchain.

In contrast, hardware oracles use actual sensors or devices to gather information from the real world and add it to the blockchain.

Blockchains with a centralized oracle depend on a central authority to supply data to the network.

Conversely, decentralized blockchain oracles rely on a distributed network of data providers to add information to the blockchain.

Dear friend you shared your searched and your thoughts about the types of blockchain oracles is really well and good.You are right software oracles is a computer software that connect the blockchain with third party data and also you mentioned good about the hardware oracles and the centralized oracle.You share some good words about decenterlizied oracles and you're right that decentralized oracles rely on distributed network of data provider.

Your thoughts about decenterlizied oracles is correct and these are more reliable and correct that centralized oracles and decentralized oracles are the advantage to more consistent.You explained very well about the use of decentralized oracles with the example of farmer that can used blockchain network.Overall, you'r blog is really informative and i wish you good luck for the contest.
