At its essence, cryptocurrency is a type of digital or virtual currency that employs cryptography for security. Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized networks based on blockchain technology. This decentralization ensures that no single entity has control over the currency, making it resistant to censorship and interference.
How Does Cryptocurrency Work?
Cryptocurrencies function through a technology called blockchain—a distributed ledger that records all transactions across a network of computers. Here's a simplified breakdown:
Transaction Initiation: A user initiates a transaction by sending cryptocurrency to another user.
Verification: Network participants, known as miners or validators, verify the transaction's authenticity.
Block Creation: Once verified, the transaction is grouped with others into a "block."
Blockchain Update: This block is then added to the existing blockchain, creating a permanent and immutable record.
Completion: The recipient's wallet balance is updated, and the transaction is complete.
This process ensures transparency, security, and trust without the need for intermediaries like banks.
