The invention discloses a deduction auction-based network bidding method, which comprises the following steps of: 1, initializing an auction rule, and generating a reference time axis; step 2, accessing a user, and carrying out synchronous
clock calibration; step 3, when the high-precision
timer reaches a preset interval time, starting to execute periodic
price reduction until a user bids or an auction state is ended; 4, when a user bidding event is monitored,
processing a user bidding request; 5, verifying the atomization state, adding an exclusive lock to the auction instance, and generating a transaction snapshot; 6, feeding back and pushing an auction transaction result; and 7, auction is terminated. According to the method,
millisecond-level periodic
price reduction is realized based on a high-precision
timer and a time slot mechanism, a dynamic update packet is pushed in combination with
MQTT, price synchronization zero
delay is ensured, and real-time accurate
price reduction is realized; and through an exclusive lock, an idempotent token and a fund freezing mechanism, over-selling and repeated transaction risks are thoroughly avoided.
