What is Cryptocurrency?
/ΛkrΙͺptΙΚΛkΚrΙnsi/ - Digital or virtual currency secured by cryptography
Cryptocurrency is a digital or virtual form of currency that uses cryptography for security and operates on decentralized networks based on blockchain technology. Unlike traditional fiat currencies issued by governments, cryptocurrencies are typically decentralized and not controlled by any central authority. They enable secure, borderless transactions and are designed to be resistant to censorship and fraud.
π The Cryptography Connection
The term "cryptocurrency" comes from combining "cryptography" (the science of securing communication) and "currency" (a system of money). Cryptography ensures that transactions are secure and that digital assets cannot be counterfeited or double-spent.
