    Double-spending is a major concern in the world of cryptocurrencies. To prevent this, crypto ledgers rely on a consensus mechanism called proof-of-work. This mechanism requires miners to solve complex mathematical puzzles in order to validate transactions and add them to the ledger. Once a transaction is added to the ledger, it becomes practically impossible to alter or spend the same digital currency again. This ensures the integrity and security of the crypto ledger.

    Preventing double-spending in a crypto ledger is achieved through the use of cryptographic algorithms. Each transaction is digitally signed using the sender's private key, which ensures that only the rightful owner of the digital currency can spend it. Additionally, the ledger keeps track of the balance of each account, making it impossible to spend more than what is available. These measures provide a robust defense against double-spending attacks.

    Double-spending is a serious issue in the world of cryptocurrencies. To prevent this, crypto ledgers utilize a decentralized network of nodes that maintain a copy of the ledger. These nodes communicate with each other to reach a consensus on the validity of transactions. By requiring a majority of nodes to agree on a transaction before it is added to the ledger, the system ensures that double-spending is virtually impossible.
