An illustrated example of how digital currency works

1

Someone announces a transaction

270,000

transactions take place in

a typical 24-hour period

2

The transaction

is signed

by the spender’s private key and broadcast to a peer- to-peer network of bitcoin ‘miners’

3

Validation

The network of miners validates the transaction, paying customers first. It takes around 10 minutes and costs $10

4

A verified transaction

can include other information, such as ‘smart contracts’, records, or links to other currencies

5

Once verified

the transaction is combined with other transactions to create a new block of data for the ledger. The new block is added to the existing blockchain in a way that is permanent and unalterable

6

Your transaction

is now on the blockchain, a historical record of every transaction ever made, right back to the first coins ever created
