BlockChain
A blockchain is a very specifc type of database where data or information is stored in blocks and then that block is added to the previous blocks. These blocks are immutable i.e the data or information once saved to these blocks remains permanently stored in them. Also each block is given a timestamp to know when exactly was it added to the chain.
Just like a database which stores information into tables or documents, blockchain stores data into different blocks that are connected to each other.
Bitcoin uses this technology to securely complete its transactions. Every transaction ever made with a bitcoin is stored in a block chain and the block chain is decentralised.
