What security measures does cryptocurrency use?

Cryptocurrency uses a variety of security measures in order to provide users with a secure, tamper-resistant digital asset. These measures include: cryptography, decentralized consensus mechanisms (such as proof-of-work or proof-of-stake), immutable ledgers, and built-in financial controls.
