A cryptocurrency is a digital or virtual currency that is protected by encryption, making it extremely difficult to counterfeit or double-spend. Numerous cryptocurrencies are decentralized networks built on blockchain technology, which is a distributed ledger enforced by a dispersed network of computers. A defining characteristic of cryptocurrencies is that they are often not issued by a central authority, which potentially renders them immune to government meddling or manipulation.
Key Takeaways:
- A cryptocurrency is a sort of digital asset that is built on a decentralized network of numerous computers. This decentralized structure permits them to operate independently of governments and central authorities.
- According to experts, blockchain and related technologies will disrupt numerous industries, including the financial and legal sectors.
- The benefits of cryptocurrencies include cheaper and faster money transfers and decentralized systems that are not susceptible to failure at a single point.
- The disadvantages of cryptocurrencies include price volatility, significant energy usage for mining, and illegal use.
How Does Cryptocurrency Work?
All cryptocurrency transactions are recorded on a distributed public ledger called blockchain, which is held by currency holders.
The technique through which units of cryptocurrency are generated is known as mining, and it entails the use of computer power to solve complex mathematical puzzles that generate coins. Users can also purchase the currencies via brokers, store them in encrypted wallets, and spend them.
If you own cryptocurrencies, you do not possess anything physical. What you possess is a key that enables you to transfer a record or unit of measure from one person to another without a third-party intermediary.
Although Bitcoin has been since 2009, cryptocurrencies and financial applications of blockchain technology are still in their infancy, and additional usage is anticipated in the near future. Eventually, transactions involving bonds, stocks, and other financial assets could be executed via this technology.
What Is a Blockchain?
A blockchain is an open, decentralized ledger that records transactions using computer code. In practice, it resembles a checkbook that has been distributed across multiple computers worldwide. Transactions are recorded in “blocks” which are then connected to a “chain” of previous bitcoin transactions.
“Imagine a book in which you record your daily expenditures,” says Buchi Okoro, CEO, and co-founder of the African bitcoin exchange Quidax. Each page is analogous to a block, and the collection of pages constitutes a blockchain.
With a blockchain, each user of a cryptocurrency has their own copy of this book to produce a centralized ledger of all transactions. Each new transaction is recorded as it occurs, and every copy of the blockchain is instantaneously updated with the new data, ensuring that all records are identical and correct.
Each transaction is validated using a technique such as proof of labor or proof of stake to prevent fraud.
Types of Cryptocurrency
Bitcoin is the most valuable and widely used digital currency. In 2008, an unidentified person named Satoshi Nakamoto revealed it to the world via a white paper. There are currently thousands of cryptocurrencies on the market.
Each coin asserts a distinct role and set of specifications. Ether, for example, is marketed as fuel for the underlying smart contract technology. Ripple’s XRP is utilized by banks to facilitate international money transactions.
Bitcoin, which became accessible to the general public in 2009, continues to be the most extensively traded and covered cryptocurrency. As of May 2022, there were more than 19 million bitcoins in circulation, with a market capitalization of approximately $576 billion. Never more than 21 million bitcoins will exist.
In the aftermath of Bitcoin’s success, other alternative cryptocurrencies have been introduced. Some of these are clones or forks of Bitcoin, while others are whole new cryptocurrencies. Solana, Litecoin, Ethereum, Cardano, and EOS are among them. By November 2021, the entire value of all existing cryptocurrencies exceeded $2.1 trillion, with Bitcoin accounting for around 41 percent of the total value.
