Hello everyone! How are you today? I am fine by the grace of Almighty.

Today I will share with us about "Blockchain". I have not so much knowledge about it. But I try to write something about it what I know.

*What is Blockchain?

-Blockchain is a technology where all records are stored in. And to change or add anything in that blockchain then it has to get permission from all of the blocks created.

It's a record keeping technology where you can find your transactions like date, time, amount etc.

*How does Blockchain work?

-When we stored new data(transaction) in a block, it is added to the blockchain.

Each transaction generated a hash. Each block instractions to the previous block and together make a Blockchain.

A Blockchain is effective as it is expansion many computers, each of which has a copy of the Blockchain.

Blockchain is a technology of the underpins digital currency, such as: Bitcoin, Litecoin, Ethereum, and the like. The technology allows digital information to be distributed, but not to copied. The information is constantly reunion into database, which is stored in multiple location and update instantly.
