Dear @drhira first of all thanks for taking part in the content and sharing your thoughts and search about Blockchain oracles with us.You made an very well blog about Blockchain oracles and i visited and read your blog and i got much more information from your blog and i wish you good luck for the contest.

Yes you're right Blockchain oracles act as a bridge between Blockchain and the interior world and oracles transfer information from world to the smart contracts of Blockchain.you explained very good point that before Blockchain oracles there is no way of connection of Blockchain with the world and then the Blockchain oracles act as a bridge between them and give access to collect the data from the world.You explain very well and easy about the major types of Blockchain oracles and it's simple to understand these types from your blog .

You mentioned about decentralized Blockchain oracles and they are more secure because firstly thier was a use of centralized but they are not much safe and these decentralized Blockchain oracles are very safe and they collect and validate data and then transfer it to Blockchain.You explained the use case of decentralized Blockchain oracles and these are very good and simple.Overall, your blog is amazing and i appreciate your blog and thanks again for sharing with us.
