In the UTXO model, the balance of each Bitcoin address is composed of a series of unspent transaction outputs (UTXOs). These UTXOs represent the Bitcoin assets within the address.\n\nThe basic principle of the UTXO model is that the assets within each Bitcoin address can only be spent once. When a user initiates a transaction, the UTXOs in their Bitcoin address will change. For example, when a user sends 5 Bitcoin to another address,"}]}],"pr":"47399c5770bb4c1cc25ac772605d72e4bd64c2c2ce14c02582f024ae805a62ff"}
