Cryptocurrency, as the name suggests, is a type of currency which uses cryptography to secure and verify transactions and to control the creation of new units.

Instead, it relies on a distributed ledger technology called blockchain to maintain a transparent and secure ledger of transactions.

Blockchain is a distributed ledger technology that allows for the creation of a tamper-proof record of all transactions on a network. Each block on the blockchain contains a cryptographic hash of the previous block, creating an immutable chain of blocks. This means that once a transaction is recorded on the blockchain, it cannot be altered or deleted.

Cryptocurrencies useblockchain technologyto create a decentralized, transparent and secure ledger of transactions. This means that anyone can participate in the network and view the ledger, but no one can alter it without consensus from the network.

One of the main benefits of using cryptocurrency is the ability to make transactions without the need for intermediaries such as banks or financial institutions. This means that transactions can be made quickly and cheaply, without the need for lengthy processing times or high fees.

Cryptocurrencies also offer a high degree of anonymity and privacy, as transactions are not tied to personal information such as a name or address. This can be particularly beneficial for individuals who are concerned about their privacy or who wish to make transactions without revealing their identity.
