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."

BBC business news:

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