Cryptocurrency is a type of digital or virtual currency that relies on blockchain technology and cryptographic techniques for secure financial transactions. Unlike traditional currencies issued by central banks, cryptocurrencies operate in a decentralized system where control is distributed among network participants rather than a central authority.
Decentralization:Cryptocurrencies are typically decentralized and operate on peer-to-peer networks.No single institution (e.g., a bank or government) controls them, making them resistant to censorship and centralized failures.
Blockchain Technology:Cryptocurrencies are built on blockchain, a distributed ledger that records all transactions transparently and securely.Once a transaction is recorded, it cannot be altered, ensuring data integrity.
Cryptographic Security:Advanced cryptographic algorithms secure transactions, protect user identities, and prevent fraud.Public and private keys are used to authorize transactions.
Digital Nature:Cryptocurrencies exist only in digital form and are not tied to physical entities like coins or notes.
Limited Supply:Many cryptocurrencies, like Bitcoin, have a finite supply, making them scarce and potentially valuable over time.
