What is blockchain?

Blockchains rely on cryptography to allow a set of computers to make changes to a global record without needing a central actor.

Removing the middleman cuts costs in almost every sector.

The blockchain is a ledger that records everything that happens to a collection of data known as a “block” in a chronological order or “chain”.

As a currency this is an important feature because it allows users to be sure their digital money is one of a kind,the same way each note in your wallet is unique.

“Blockchain tech will be the way we create assets because it allows you to transfer digital information without copying,” says Adam Ludwin,chief executive of Chain.com,which builds blockchain networks.

Blockchain can be used to track the history of all sorts of information and maintain its value,so,for example,doctors could use it to update medical records.

Since each change to a blockchain is made simultaneously across the whole network,no information is lost and because changes cannot be undone the system maintains its transparency. A special key is needed to make changes to each block,so individuals can keep their records safe by protecting that key.
