What is Cryptocurrency?
Cryptocurrency is a digital currency that uses blockchain technology for secure and transparent transactions. Unlike traditional currencies, cryptocurrency is decentralized, meaning no central authority, like a government or bank, controls it.
Bitcoin, Ethereum, and Ripple are popular examples of cryptocurrencies. They operate on peer-to-peer (P2P) networks, enabling users to send and receive payments directly without intermediaries. Transactions are recorded on a blockchain, ensuring transparency and immutability.
For those new to crypto trading, you may need a secure crypto wallet to store your assets. Check out this recommended hardware wallet on Amazon.
How Does Blockchain Work?
Blockchain is the underlying technology behind cryptocurrency. It’s a decentralized ledger that records transactions across multiple computers. This ensures that no single entity has control over the data.
Each transaction is stored in a block and linked to previous transactions, forming a chain—hence the term blockchain. Transactions are verified through cryptographic algorithms and consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).
