Taking Bitcoin as an example, the initial duration of the large cycle is 10 minutes. However, this duration gradually increases over time, as the Bitcoin protocol stipulates that the duration of each large cycle is adjusted every 2016 blocks to maintain a block generation rate of approximately 10 minutes. This means that as time goes on, the duration of the large cycle  increases, resulting in the gradual slowing down of the entire blockchain network's operation."}]}],"pr":"e92a4797f76ccba9499e83523ad82d73ed8a521838664ec76b062a7ebb680f32"}
