Hello @allbert and @asaj . Let's start to explain what is Blockchain Oracle first and then we can go on at a Blockchain Oracle project : DOS Network explanation.
What is Blockchain Oracle
Blockchain Orcale are systems that connect the blockchain system with the outside world, that is, our world. By our world, I mean everything except the blockchain system. For example, we can think of it as the outside world, the internet itself, or any development or news.
To summarize more simply, Blockchain Oracle is a system that mediates the understanding of smart contracts in the blockchain and the normal world.
So why is there a need for a mediator, namely Blockchain Oracle, for the outside world and smart contracts to understand each other?
Because they both speak different languages. Smart contracts read and understand their own language within the blockchain system and we already know the outside world. That's why these two parties need Blockchain Oracle to talk to each other. Think of it like a translator of sorts.
A Blockchain Oracle Project : Dos Network | History and Description. Does it have any token or cryptocurrency associated? | Functionalities and real-life applications. | Pros and Cons. | Future developments and new projects
A DOS Network Coin is $0.004681 at the time of this writing, according to CMC. We see it in the Green Box.
The total market value of DOS Network 6 362 762 $ at the time of this writing, according to CMC. We see in the Red Box.
You can reach any information abour DOS Network by using this CMC link.
So, What is DOS Network?
Because blockchain smart contracts are isolated from the normal world, they cannot directly access data in our world.
DOS Network is a decentralized platform that supports multiple platforms.
DOS Network enables smart contracts to detect calculations, data, events in the outside world in a fast scalable manner.
DOS Network published its first Medium article on October 6, 2018.
DOS Network, Decentralized Oracle Service consists of the initials of the words.
Let's check Mainpage
And here DOS Network Main Page Link
This mainpage seems very nice for the first impression.
This is Overview Section above. A problem has been written on this page. The problem is that smart contracts in the blockchain system and the outside world do not understand each other.
Below the problem is written how to solve this problem. The solution is this: There is a system that supports multiple platforms. The name of this system is DOS Network. DOS Network makes external world data fast, scalable and reliable, and translates it into the language smart contracts understand on the blockchain.
This is Innovation section above. It says DOS Network is Decentralized and Reliable , Real-Time and Verifiable , Compatible to Heterogeneous Blockchains , Secure and Trustworthy , Scalable at a Low Cost , Crypto Incentivized.
There is Use Cases section above. Automatic Decentralized Insurance Payout , Stablecoins and Crypto Derivatives , Crypto Lending Platform , Cross-chain Dex , Computation Marketplace are some of abilities of DOS Network.
There are some partnerships above. Especially, Huobi, Quarkchain, ForTube, Google, China News and Etherium Alliance partnerhips caught my attention.
There is a roadmap above. It is very good expanding on Binance Smart Chain and Etherium. There are some developments awaits us on Q3-Q4 2021, for example Releasing Oracle Chain Mainnet and Prepare for Parachain Auction
, Reseaching Optimism Rollup to Introduce DOS to L2 Network and DAO Setup for Network Parameters and Decentralized Governance.
Yes, I have always mentioned the positive aspects of this project above. The website, its partnerships, its usefulness, the completed developments in the roadmap and the developments that await us are very impressive.
But every project has its good sides as well as handicaps. The biggest problem of this project is that it promises almost the same things as its competitors.
What is this project for? This project is for blockchain oracle. This project is to integrate the real world and the blockchain world. Other blockchain oracle projects offer the same thing. Integration.
Who are these projects? Chainlink, Band Protocol, Dia, Zap, Tellor, Nest Protocol and the like. All projects are for the same thing. DOS Network's biggest competitor is ChainLink, and this project is quite advanced compared to others.
Conclusion
First of all, I would like to thank @allbert and @asaj for preparing this homework for providing me with knowledge on such a beautiful subject.
In this article, I briefly touched on what Blockchain Oracle means. The big problem is that the outside world and the blockchain system do not understand each other. Blockchain Oracle projects are helping smart contracts understand the outside world.
I reviewed one of these projects, DOS Network, and liked it. Nice and useful project. The downside is that his opponents are too strong. Thank you for reading.
