What is Cryptocurrency?
Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Cryptocurrencies are not controlled by central banks or governments, they are decentralized and run on a technology known as blockchain. Cryptocurrencies such as Bitcoin and Ethereum are used for online transactions, investing, and even as a form of storing value, similar to gold.
Blockchain Technology
Blockchain technology is a key part of how cryptocurrencies work. A blockchain is a digital log of transactions that is duplicated and distributed throughout the network of computers participating in the blockchain. Each such computer, or node, has a copy of the entire blockchain and works to confirm and record new transactions.
Each block in a blockchain contains a list of transactions, a hash of the previous block (a unique digital fingerprint), and its own unique hash. Through the use of hashes, each block is inseparably linked to the previous block, which ensures the integrity and security of the data in the blockchain. When a new transaction is made, it is verified by a network of nodes. If the majority of nodes validate the transaction, it is written to the blockchain. This process ensures the decentralized and transparent nature of cryptocurrency, and it is because of this that cryptocurrencies do not need intermediaries such as banks.
Cryptocurrency Security
Thanks to blockchain technology, most cryptocurrencies have a high level of protection against fraud and cyberattacks. Why cryptocurrencies are safe:
- Because cryptocurrencies are usually not controlled by centralized authorities such as banks or governments, they are more resistant to manipulation and tampering.
- All cryptocurrency transactions are encrypted using sophisticated cryptographic algorithms. This means that transaction and wallet data is very difficult to hack.
- Thanks to blockchain technology, all transactions are recorded in a registry that is open to all participants in the network. This makes the transaction process transparent and open to scrutiny.
- Some cryptocurrencies, such as Bitcoin, provide the user with a certain level of anonymity. Although all transactions are recorded on the blockchain, the identities of the users tend to remain hidden.
