Figure 5. Number of transactions per unit time Figure 6 shows the measurement values of the delay times of the blockchain transaction performed. Minimum delay, maximum delay and average delay are given in the same graph. As shown in the graph, the increase in the delivery rate per unit time causes the delay time to increase. Considering the amount of work sent per unit time in the performance test environment to determine the limits of the system, and considering the security contribution obtained, the delay time is considered to be a quite acceptable value.
