The Blockchain and Data Sharing Frontiers 

The blockchain is a distributed database of records or public ledger of digital events or transactions of virtual currencies. That is executed and shared across a large network of untrusted participants.

In other words, it is a continuously updated record of who holds what.  The records are split into linked blocks and secured using cryptography through maths and code. Automated trust is achieved via smart contracts, that are held on a distributed ledger.
