What is Block Chain?


As the name itself describes that block chain is a chained(connected) blocks. Here the blocks will contain 4 contents within them the 1st content in the block is the hash value this would be cryptic hash value that will be used within the next block to identify its previous block the first block in the series that doesn't have the previous hash value would be called the Genesis node.
 
Every node in a block chain will have the copy of every node. So when ever a new node has to be added to the chain the copy of that block is shared with all the nodes for computing/processing if the node is successfully computed then the block will be added to the sequence   

Time-Stamp series of immutable records of data that is managed by the cluster of computers that is not owned by any single entity. Each of these blocks of data is secured and bound to each other using cryptic principles.
