Blockchain Technology

 It may be hard to understand "what's the big deal" when you say Blockchain because most people haven't come into contact with it yet. When explaining what Distributed Ledger is, it is not clear and can be more confusing. In fact, if you want to understand easily, you can see Blockchain as the Internet.

The current Internet can be called Centralized Internet. DNS servers are under the control of the respective server owner. Services such as Facebook, Google, Twitter, and Amazon are under the control of their respective owners.

Blockchain is Decentralized Internet. Anyone can participate as a node on a network that spans the globe. Facebook has spread its servers all over the world. Yes. The difference is that the Facebook servers that are spread around the world are under the direct management of Facebook, and all the information on these servers is under its control. In the Blockchain network, because anyone can participate as a node, the information is no longer controlled by someone. Being on a public network has happened.

So, what if people want to access that information? It is the essence of Blockchain that it has been developed so that it cannot be done like that. Cryptographic technologies are used and are currently mainly used in the finance industry, so they are called Cryptocurrency. It's actually much broader than that. I can't tell you how it was done here. You can read it in the short book Bitcoin.

If you still don't understand it, it doesn't matter. As a summary, if you remember that Blockchain is Distributed Internet, you can see a little more than before.

So, in summary above, Blockchain technology is beneficial for all industries. There is no need to ask which industry the Internet is beneficial to. It can be seen that it is beneficial for all. Media, Commerce, Healthcare, Finance, Science & Technology, Employment, etc. There is hardly any sector that is not benefited by the Internet.

Blockchain is currently being widely used as a cryptocurrency, mainly in the finance sector. Loan under the title DeFi, savings exchange Financial services such as investment are being implemented as decentralized without the need for centralized organization control.

Actually, DApps still exist. Little known. Social media such as Facebook and Twitter have started to be decentralized on Blockchain. Streaming services like YouTube and Spotify have also started to become decentralized. Ecommerce like Amazon is coming.

Here, I would like to add about a cryptocurrency called VeChain (VET). It is a prominent Crypto that is currently at the level (22) of the Coin Market Cap. It's not like any other crypto. Supply chain management project. This is -

Let's say we manufacture a wallet. Starting from the tannery stage, in which region? How much does it weigh? What color it is, etc. will be recorded on the Blockchain. So it cannot be edited or deleted. When finished, the color is bad, branding When it comes to the sewing stage, where is the color, Where it is sewn, etc. will be recorded. When you arrive at the garage, what day did you arrive? Where, etc. will be recorded. When we finally got to the shop, how much did we sell it for? We will record everything step by step, such as where the store is laid out.

In this way, supply chain management will be managed, so when the buyer reaches the last shop, he can scan the QR code and know everything about the item, and the owners and sales representatives can easily track the complete record of the item.

This is a selected use case of Blockchain. There are still many unique and useful use cases like that.

It's going to be too confusing, but I want to add it. Blockchain is called Decentralized Internet, but it can also be considered as Decentralized Database. I eat a lot. It is still a new technology.

Just because it is new from now on, there are new and undiscovered areas of use that do not exist yet. There are new opportunities. It will be beneficial if you can participate and take it as a mother.
