Cryptocurrency operates on blockchain technology, a decentralized ledger system. Transactions are recorded in blocks, cryptographically linked and stored across a network of computers. Each transaction is verified by network participants, ensuring security and preventing fraud. Cryptography secures transactions and controls the creation of new coins. Decentralization removes the need for intermediaries like banks. Users store cryptocurrency in digital wallets, accessed via private keys. Transactions are broadcasted to the network, confirmed through consensus mechanisms like Proof of Work or Proof of Stake. Miners validate transactions, earning rewards for their efforts. Once confirmed, transactions are irreversible. Cryptocurrency's workings offer transparency, security, and autonomy, revolutionizing financial systems globally.
