What is Blockchain Technology ?
Blockchain is a digital ledger in which every transaction is being stored in blocks . This is the network of thousand of computers placed at different places in a decentralised way . As data is stored in a block , every block has a hash number which also stores the hash number of previous block . When one block become full it is linked with previous block . Thus all the previous blocks are linked with their next block . Due to decentralized system , no one can edit or manipulate the data , If anyone want to do this , the transaction will be cancelled . So it is secure and safe .
There is no any central agency involve in cryptocurrency . If we talk about physical currency of any country , a central agency is involved , e.g. Indian currency is regulated by Reserve Bank of India , in USA , Federal Reserve controls the US dollars .
