  Cryptocurrencies like Bitcoin ensure security through the use of cryptographic techniques. These techniques involve the use of complex mathematical algorithms that encrypt and secure transactions. Each transaction is verified and recorded on a decentralized public ledger called the blockchain. The blockchain is maintained by a network of computers known as miners, who validate and confirm transactions. This decentralized nature of the blockchain ensures that no single entity has control over the network, making it resistant to hacking or tampering.

  The security of cryptocurrencies like Bitcoin is also ensured through the use of private and public key pairs. Each user has a unique pair of keys: a private key and a public key. The private key is kept secret and is used to sign transactions, while the public key is shared with others to receive funds. Transactions are only considered valid if they are signed with the correct private key, ensuring that only the rightful owner can access and transfer their funds.
