What is Cryptocurrency and how does it work?

Cryptocurrency – Meaning and definition

Cryptocurrencies are digital tokens. They are a type of digital currency that allows people to make payments to each other directly through online systems. Cryptocurrencies have no legal or intrinsic value; they are only worth as much as people are willing to pay for them in the market. This is in contrast to national currencies, which get a portion of their value from being adopted by law as legal tender. There are many cryptocurrencies – the most well-known of these are bitcoin and ether. Activity in cryptocurrency markets has increased significantly. The attraction to these currencies appears to be more speculative than being related to their use as a new and unique system for making payments. Related to this, there has also been a high level of volatility in the prices of many cryptocurrencies. The first cryptocurrency was Bitcoin, which was founded in 2009 and remains the most popular today. Most of the interest in cryptocurrencies is to trade them for profit, with speculators often driving prices sky high.

For example, the price of bitcoin rose from around US$30,000 in mid-2021 to around US$70,000 by the end of 2021, before falling to around US$35,000 in early 2022. Currently it has crossed US$ 104000 in December 2024 .Rival cryptocurrencies such as Ether have also experienced similar volatility. The extraordinary interest in cryptocurrencies has also seen an increasing amount of computing power used to solve the complex codes that many of these systems use to help protect them from being corrupted. Despite the growing level of interest in cryptocurrencies, there are doubts about whether they can ever replace more traditional payment methods or national currencies.

How does cryptocurrency work?

Cryptocurrencies are digital assets that use blockchain technology to enable secure, decentralized transactions. Unlike traditional currencies, they are not controlled by governments or central banks. Instead, they rely on a distributed ledger system, where transactions are verified by a network of computers (nodes) through cryptographic methods. Units of cryptocurrency are created through a process called mining, which involves using computer power to solve complex mathematical problems that generate coins. Users can also buy currencies from a broker, then store and spend them using a cryptographic wallet. If you own cryptocurrency, you don’t own anything tangible. What you do have is a key that allows you to move a record or unit of measurement from one person to another without a trusted third party.

Key Components of Cryptocurrency

1.Blockchain Technology:

A blockchain is a public, decentralized ledger that records all transactions. Each block contains transaction data, a timestamp, and a cryptographic hash that links it to the previous block, ensuring security and transparency.

2.Decentralization:

Unlike traditional financial systems, cryptocurrencies operate on a peer-to-peer (P2P) network, meaning no single entity has control. This reduces the risks associated with censorship or manipulation.

3.Cryptographic Security:

Transactions are secured using advanced cryptography. Public and private keys ensure that only the rightful owner can access and transfer funds, making transactions both secure and verifiable.

4.Mining and Verification:

Cryptocurrencies such as Bitcoin use Proof of Work (PoW), where miners solve complex mathematical problems to verify transactions and add them to the blockchain. Others, such as Ethereum 2.0, use Proof of Stake (PoS), where validators are selected based on the amount of cryptocurrency they hold and stake.

5.Wallets and Transactions:

Users store their cryptocurrencies in digital wallets, which can be online, offline, or hardware-based. Transactions involve sending assets from one wallet to another using unique addresses, and once verified, they are permanently recorded on the blockchain.
