### Why Is It Called a Chain?
Each block in the blockchain stores a hash of the block before it. This links the current block all the way back the original "genesis block" through an unbroken chain. This also provides the security of blockchain, because each block stacked atop an old one makes it harder to recreate the old block due to the proof-of-work algorithms used in block creation. Once several blocks have been built atop a block in the chain, it's essentially irreversible.
Each block in the blockchain stores a hash of the block before it. This links the current block all the way back the original "genesis block" through an unbroken chain. It's a way to create absolute order among possibly conflicting data.

### Blockchain — In Short
One way to think of blockchain is: _a linked series of blocks of unchangeable data, going back in time_.
