  Cryptocurrencies prevent double spending through the use of a decentralized ledger called a blockchain. When a transaction is made, it is verified by multiple computers, known as nodes, on the network. These nodes check if the sender has enough funds and if the transaction is valid. Once the transaction is confirmed, it is added to a block and linked to the previous blocks in the chain. This creates a permanent record of the transaction that cannot be altered. Additionally, cryptocurrencies use cryptographic techniques to secure the transactions and prevent tampering.

  To prevent double spending, cryptocurrencies rely on the consensus mechanism. This means that the majority of the network participants must agree on the validity of a transaction before it is considered confirmed. This prevents any single entity from controlling the network and manipulating transactions. The consensus mechanism ensures that only one valid transaction can be added to the blockchain, eliminating the possibility of double spending.
