Cryptocurrency is decentralized digital money built on blockchain technology. While Bitcoin and Ethereum are the most recognized, there are over 9,000 different cryptocurrencies in circulation today.
How Does Cryptocurrency Work?
Cryptocurrency is a digital, encrypted, decentralized form of exchange. Unlike traditional currencies like the U.S. Dollar or Euro, cryptocurrencies are not managed by any central authority. Instead, control is distributed across a network of users via the internet. While cryptocurrencies can be used for purchasing goods and services, many treat them like other assets, such as stocks or precious metals. However, understanding the risks and intricacies of cryptocurrency systems is crucial before engaging with them.
What Is a Blockchain?
A blockchain is an open, distributed ledger that records transactions across multiple computers. Each transaction is stored in a "block," and these blocks are connected in chronological order, forming a "chain." This technology ensures that all users maintain an identical and accurate record of transactions, preventing fraud by requiring validation through methods like proof of work or proof of stake.
Proof of Work vs. Proof of Stake
Proof of Work involves solving complex mathematical problems to verify transactions. Miners, or participants, compete to solve these puzzles, and the first to succeed adds the new block to the chain, receiving a cryptocurrency reward. This method requires substantial computing power and energy, which can reduce the net benefit for miners.
Proof of Stake, on the other hand, is more energy-efficient. In this method, validators are selected based on the amount of cryptocurrency they "stake." Those who lock up more crypto have a better chance of verifying transactions, which leads to faster and less resource-intensive verification.
Mining Cryptocurrency
Mining introduces new units of cryptocurrency by validating transactions. While anyone could mine in the early days, mining has become increasingly complex and expensive, particularly for proof-of-work systems like Bitcoin. Proof-of-stake systems, however, are more accessible, as they don't require high-powered computing but do require ownership of cryptocurrency to participate.
How Can Cryptocurrency Be Used?
Cryptocurrencies like Bitcoin, Litecoin, and Ethereum can be used for various purchases. They are also considered alternative investment opportunities, offering another option beyond traditional stocks and bonds.
