Blockchain

 
 
A blockchain is a distributed database managed by a peer-to-peer network. The distributed database is also called a ledger which is a continuously growing chain of blocks. Each block contains a number of records and each block is linked to a previous block.

It is extremely difficult to change a record in any given block without the alteration of all subsequent blocks and the collusion of the network.

The first implementation of a blockchain was Bitcoin in 2009 invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto.

After the Bitcoin success many blockchain implementations followed such as Litecoin and Peercoin.

Other blockchain implementations introduces new kind of functionalities such as Ethereum and Dash.
