Blockchain is a shared public collection of financial accounts that stores a permanent and tamper-proof ledger of transaction data.
Blockchain can be viewed as a type of database that forms the underpinning for the digital currency Bitcoin. The technology provides an immutable, or un-changing record of transactions.
The databases consist of two types of records, individual transactions and blocks, which are all collections of data pertaining to the transactions within a set time period.
