# <center>Introduction</center>
Hello my fellow kids and kids lovers, I am happy to partake in this assignment titled "crypto Academy, Blockchain technology." Well, this is my first time to hear the word Blockchain. But after going through the lecture, I got a clear understanding about what Blockchain is all about. I think @steemkidss community is trying to enlighten us the kids more on the digital marketing. Now, I can proudly walk up to my parents to explain what a Blockchain is, I guess they will wonder where I've learnt it from.



•1 **The first Question is: What is Blockchain Technology?**

A Blockchain is the orderliness of blocks that are linked to one another. Each block is linked to the already existing block. The first ever block is called **Genesis Block.**

In a blockchain technology, when information are stored, it is always so difficult to get that information destroyed. We have a first block that is linked to another block that is also linked to another block so when an important information is stored on a blockchain, even the system hackers cannot get it hacked.

I also understood that in a blockchain, you don't deal with a third-party, it is just you and the next person. In A blockchain technology, transactions are made fast and in an easy way too. 

>My dad showed me how he does his transactions and I think it is easier and faster. He deal on cryptocurrencies, but he never explained it to me until after this class then I asked some questions and he started explaining things to me.

**We have different types of Blockchain like;**
•Public Blockchains
•Private Blockchains
•Consortium Blockchains
•Hybrid Blockchains


**Uses of a Blockchain;**
•A blockchain is used for cryptocurrency exchange.
•Security for personal identity.
•It can also be used for original content creation.



•2 **The Second Question is: What makes up a blockchain?**
•Block: This is the foundation. It is connected to the system, where you find tracks of all the transactions done over the years.

•Data: These are the stored information in the block which no one can destroy.

•Hash: This is a kind of identity used to identify every blockchain.
