what is Blockchain technology?

Blockchain is a Distributed Immutable Ledger which is transparent.

• Ledger In Blockchain our block is our Ledger book, ledger where all the transaction entries are store.

• Immutable Once a data is feed into a Block, the data becomes immutable(unchangeable or fixed). If a transaction happens it becomes a block, and As a block created that block is added into a blockchain, first of all block becomes immutable.

• Distribute next As soon as the block is added into a blockchain,this block will Distribute the block in its network.(your transaction will be saved in all the computer who's computer will be connected to that blockchain network).

• Transparent It is Transparent because the same block is everywhere in A's system ,B's system,C's systems or D's system, if anybody tries to make any changes it will be visible to all other system,so there will be no unfairness is a situation. all the transactions are crypt with cryptography so with a secret code these transactions are shown not the actual transaction show to everyone only the own can view the transaction others will have the same secret code in there system.
