When a transaction is generated, a Nonce (Number used once) will be generated along with the current timestamp or another unique identifier and included in the transaction data. Then, when processing the transaction, the validation nodes will compare the Nonce  in the transaction with the current timestamp or another unique identifier to ensure that the transaction is within its validity period. If the Nonce in the transaction matches the current timestamp or another unique identifier, the validation nodes will consider the transaction valid, thereby ensuring that it does not expire. This method serves as a guarantee that transactions are valid and effective, contributing to the security and reliability of the blockchain system."}]}],"pr":"c6ebb8e0c15a6f60347c4d643ae47d3273ca04fcbe96e0172c869d24d654a08c"}
