What is crypto?
It's digital.
- Crypto is completely digital. It exists in data files stored in many computers around the world.
- Crypto is unique because it makes it so certain data can’t be duplicated. For example, while you can easily copy and paste a file in your computer, you can’t copy and paste Bitcoin data to create new Bitcoin.
It’s like currency.
- Because crypto data can’t be duplicated in this way, it can be used like currency to store and transfer value. If you own crypto, only you have access to it and only you can send it to someone else.
- Before crypto and blockchain technology, no one had figured out how to do this digitally without having someone in the middle keeping track of who owned what.
- Crypto allows people to use money online on a peer-to-peer basis, just like physical cash.
It’s powered by cryptography
- You might wonder why any of this is called ‘crypto’ in the first place. The reason is that cryptography plays a big role in how the underlying technology, blockchain, works.
- Cryptography refers to techniques that are used to encode information in secure ways. In blockchains, it allows people to prove ownership of their money and authorize spending—digitally.
- Cryptography also makes blockchains hard to corrupt or change, which helps keep people’s money safe.

What is a blockchain?
Blockchain is a digital record-keeping system that’s run by a network of computers around the world. Think of it like a book that’s designed to keep a running record of every crypto transaction that’s ever been made on that blockchain. These records are shared and stored in computers on the blockchain network at all times. This makes blockchains hard to hack, because there’s no single point of weakness in their security systems. The first and most famous example of this technology is the Bitcoin blockchain, which keeps a digital record of every time someone sends or receives Bitcoins (BTC).
