  UTXO plays a crucial role in the transaction verification process of cryptocurrencies. When a transaction is made, it creates new UTXOs, which represent the unspent funds from the previous transactions. These UTXOs are stored in the blockchain and serve as the inputs for future transactions. During the verification process, the UTXOs are checked to ensure that the sender has sufficient funds to complete the transaction. This helps prevent double-spending and ensures the integrity of the transaction history.

  In the transaction verification process of cryptocurrencies, UTXO acts as a record of unspent funds. When a transaction is initiated, it consumes certain UTXOs as inputs and creates new UTXOs as outputs. These UTXOs are then stored in the blockchain and can be used as inputs for future transactions. By checking the UTXOs, the network can verify the validity of a transaction and ensure that the sender has enough funds to complete it. This mechanism adds a layer of security and prevents fraudulent activities like double-spending.

  UTXO, or Unspent Transaction Output, is a fundamental concept in the transaction verification process of cryptocurrencies. It represents the unspent funds from previous transactions and serves as the inputs for new transactions. When a transaction is initiated, the UTXOs associated with the sender's address are checked to ensure that they have enough funds to cover the transaction amount. This verification process helps maintain the integrity of the transaction history and prevents the same funds from being spent multiple times. UTXO-based transaction verification is a key component of the security model of cryptocurrencies.
