Answer 1

 Block chain is a continually growing list of records called blocks which are linked and secured using cryptography.  Each block typically contain a cryptography hash, a timestamp and a transaction data.  A hash is a unique digital signature generated cryptography which links the two subsequent blocks to form a chain. 

The three concept used to explain the foundation of block chain are the block, the chain and the network. A block is a time bound collection of data that is published into ledger entered into the block chain  over a given period of time. 

A chain is a collection of blocks that are linked together referencing hashes from the previous block.  Hash being the glue that holds the block chain together and creates trust.

Network consists of computers that host the information entering the block chain via transaction.  Before any permanent entry is made into the block chain, all nodes verify the transaction. Nodes are computers or system operating on a larger network.
