Usually, I am very interested to know and learn about technology and now I have learned a lot by my efforts though not much. When I was working in the Amar Bangla blog community I had no idea about blockchain, bitcoin, steam. When it came to Amar Bangla blog I started working and slowly started to know. Then I was surprised to know about this blockchain. And slowly I started to know what blockchain thing is and how it works. I started reading various video blog documentaries and got to know a lot of things. And to be a part of that little knowledge, today I am sharing what is blockchain? And what is the function of blockchain?

This technology is called the blockchain. This technology contains a lot of data, all the data blocks are encoded using cryptography technology. And the blocks that are created combine to form a long chain. One of the previous blocks is a cryptographic hash. And there is also a timestamp and all the information of the transaction.

Blockchain is a old technology. This technology was first coined by Stuart Haber and W. Scott in 1991. The main purpose of this technology was to timestamp digital documents. No one can steal or change it. Bitcoin was created using it. And as a result of this discovery, blockchain has become a point of interest for every one day by day. Blockchain is now considered to be the future of the world economy. It was created to support the cryptocurrency after its invention. It is now so popular and modern that Bitcoin cannot exist or be imagined without it.
