Input-triggered transaction expiry

The explanation provided clarifies a specific scenario in transaction processing where the validity of a second transaction is contingent upon the timing of the first transaction's confirmation. If the first transaction is confirmed too late, the subsequent transaction becomes invalid. This insight simplifies the understanding of transaction dependencies and their impact on system operations, particularly in environments where timing and sequence of operations are critical. The focus is on ensuring clarity in how transactions are handled and the consequences of delays in confirmations within such systems.
