“Alright boss, let me break it down for you. Bitcoin is like this stash of cash we got hidden away, see. Only instead of being in a physical place like a safety deposit box, it’s all digital, get it? And just like regular money, you can use it to buy things, but there’s a few key differences.” What is bitcoin in simple terms Bitcoin is an unregulated, digital currency. Bitcoin uses blockchain technology as its transaction ledger.
Step inside the basics of blockchain technology: how blocks contain data representing anything of value, how they’re chronologically connected in an immutable chain, and the differences between blockchain and cryptocurrencies such as Bitcoin.

What is Bitcoin Another difference between public and private blockchains regards participant identity. Public blockchains “are typically designed around the principle of anonymity. … A private blockchain consists of a permissioned network in which consensus can be achieved through a process called ‘selective endorsement,’ where known users verify the transactions. The advantage of this for businesses is that only participants with the appropriate access and permissions can maintain the transaction ledger. There are still a few issues with this method, including threats from insiders, but many of them can be solved with a highly secure infrastructure.”
Bitcoin was designed to solve this problem by using a specific type of database called a blockchain. Most normal databases, such as an SQL database, have someone in charge who can change the entries (e.g. giving themselves a million X dollars). Blockchain is different because nobody is in charge; it’s run by the people who use it. What’s more, bitcoins can’t be faked, hacked or double spent – so people that own this money can trust that it has some value.
