Blockchain defined

"At its heart, blockchain is a relatively straightforward concept. It is a ledger of blocks of information, such as transactions or agreements, that are stored across a network of computers.
This information is stored chronologically, can be viewed by a community of users, and is not usually managed by a central authority such as a bank or a government. Once published, the information in a certain block can't be changed.
If people try to tamper with that information, it becomes obvious."

Cryptocurrencies such as Bitcoin may require blockchain technology but the use of blockchain does not require the involvement of Bitcoin.
