What Is Cryptocurrency?
Cryptocurrency is a type of digital or virtual currency that uses cryptography for security and operates on decentralized networks based on blockchain technology. Unlike traditional currencies issued and controlled by governments or central banks, cryptocurrencies rely on distributed ledger technology to maintain a transparent and secure record of all transactions.
Here’s how cryptocurrencies generally work:
Decentralization:
Cryptocurrencies are decentralized systems, meaning they don’t rely on a central authority like a bank or government to validate and record transactions. Instead, they use a network of computers, often referred to as nodes, to collectively maintain the blockchain.
Blockchain technology:
The blockchain is a public ledger that contains a chronological and immutable record of all transactions across the cryptocurrency network. When a new transaction occurs, it is grouped with other transactions into a block. Each block is then added to the chain in a permanent and sequential manner, making it difficult to alter past transactions without consensus from the majority of the network.
Cryptography for security:
Cryptocurrencies use cryptographic techniques to secure transactions and control the creation of new units. Public and private cryptographic keys are used to facilitate secure and private transactions. The public key acts as an address for receiving funds, while the private key is required to sign and authorize transactions.
Mining and Consensus:
In many cryptocurrencies, including Bitcoin, a process called mining is used to validate transactions and add them to the blockchain. Miners compete to solve complex mathematical puzzles, and the first one to find the solution gets to add the next block to the blockchain. This process is resource-intensive and requires significant computational power. It ensures that the network reaches a consensus on the state of the ledger without relying on a centralized authority.
Limited supply:
Most cryptocurrencies have a predetermined supply cap, meaning there is a fixed maximum number of units that will ever be created. For example, Bitcoin has a maximum supply of 21 million coins. This limited supply can help prevent inflation and maintain the value of the cryptocurrency over time.
Peer-to-peer transactions:
Cryptocurrencies enable direct peer-to-peer transactions without the need for intermediaries like banks. Users can send funds to each other globally, and transactions are usually faster and cheaper compared to traditional financial systems, especially for cross-border payments.
