Cryptocurrency networks need computational power to run securely. The world’s most powerful blockchains are supported by millions of computers around the world.
Unlike paper money, Bitcoin and other cryptocurrencies are produced mathematically and held digitally.
The people who voluntarily offer their computing power to secure these cryptocurrency networks are called miners.
Cryptocurrencies don’t have a central government or other so-called ‘middlemen’ that decide about the future of the system. –
They are in fact digital, borderless democracies in which miners vote with their computing power to reach order and consensus.
