A Nonce is a one-time use number that increments with each transaction, ensuring the uniqueness of the transaction and preventing replay attacks. When a user initiates a transaction, they include the current Nonce value in the transaction data. Then,  the blockchain network verifies whether the Nonce value is correct. If it is, the transaction is included in the next block. This way, transactions do not expire because the incrementing attribute of the Nonce ensures its uniqueness in each transaction."}]}],"pr":"18864b86dff2ee1985f23ae43738f1ff2a0ef7ee9614f5f60bd4ac7d25f9eb93"}
