How does cryptocurrency protect data and transactions?

Cryptocurrencies use powerful cryptographic methods to ensure the security of their transactions and protect users' data. Each transaction is encrypted using complex algorithms, making it virtually impossible to hack. The blockchain, on which most cryptocurrencies are based, is a distributed database where each record is verified by many participants in the network, eliminating the possibility of manipulation. Also, anonymous technologies such as zk-SNARKs are used to protect users' identities. This approach ensures that transaction data remains protected while the transactions themselves are transparent and resistant to falsification.
