Cryptocurrency is a digital or virtual asset that uses cryptography to secure transactions and control the creation of new currency units. Cryptocurrencies are decentralized and not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009.
Cryptocurrency is often associated with blockchain technology. Blockchain is a distributed database that allows for secure, transparent, and tamper-proof transactions. Blockchain can be used for various applications beyond cryptocurrency, such as supply chain management, identity management, and voting systems.
