How are cryptocurrencies connected to the blockchain and how does this affect their security?
Cryptocurrencies are digital assets that are secured by cryptography and stored on a distributed ledger, known as the blockchain. This ledger is a public record of all transactions that have taken place, and it is secured by a network of computers. This makes it virtually impossible to alter or delete any transaction, making it highly secure. The blockchain also allows for faster and more secure transactions, as well as greater transparency and trust. This makes cryptocurrencies a secure and reliable form of digital currency.
