Cryptocurrency (Crypto)
Short for cryptocurrency, a digital or virtual currency that uses cryptography for security.
What Is Crypto?
Cryptocurrency (crypto) is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies like the dollar or euro, cryptocurrencies are decentralized and typically operate on technology called blockchain.
How It Works
- Digital Coins: Unlike the money in your wallet, cryptocurrencies exist only in digital form. You can’t touch or hold them.
- Blockchain Technology: Most cryptocurrencies use blockchain technology, which is a secure, distributed ledger that records all transactions across a network of computers. This makes it hard to tamper with or counterfeit as you’d have to alter the blockchain on ALL the computers at the same time.
- Transactions: When you send someone a cryptocurrency, the transaction is recorded in the blockchain. This ensures that the same coin isn’t spent twice (no double-spending).
- Wallets: To use cryptocurrencies, you need a digital wallet. It’s like a bank account but only for digital money. It stores your private keys, which are like secret passwords that let you access and spend your coins.
- Decentralization: Cryptocurrencies are not controlled by any central authority, like a government or bank. This gives users more control over their money and often leads to lower transaction fees.
Example
Bitcoin is the first and most well-known cryptocurrency. If you want to buy a coffee using Bitcoin, you’d use a wallet app on your phone to send Bitcoin to the coffee shop’s wallet. The transaction is verified and recorded on the blockchain, ensuring it’s secure and legitimate.
Key Takeaways
