### Block Transaction Rate Analysis
Also, from the 11 th node to the 15 th node, the network has a mean block transaction rate of 15.14, 18.71, 15.14, 15, and 18 blocks per second, while from the 16 th node to the 20 th node has a mean block transaction rate of 18, 16.29, 16.86, 15.57 and 18.57 blocks per second, respectively. Figure 15 shows the number of block transactions per second by seven Monero blockchain nodes. As the results indicate, the Monero blockchain network with seven blockchain nodes transmits 50-100 blocks per second over the blockchain network. The results show that the Monero blockchain algorithm transmits more blocks than the Hydrachain blockchain algorithm. The first and second blockchain nodes have mean block transaction rates of 75.71 and 66.86 blocks per second, respectively, while the third and fourth blockchain nodes have recorded mean block transaction rates of 83.86 and 78.43 blocks per second, respectively. Also, the fifth and sixth blockchain nodes have mean block transaction rates of 78.43 and 70 blocks per second, respectively, while the seventh node has a mean block transaction rate of 75 blocks per second [44]. As per the results shown in Figure 16, the block transaction rate of the network with fifteen Monero blockchain nodes deviates from 35 to 75 blocks per second. Compared to the network with seven blockchain nodes, the block transaction rate of the fifteen blockchain node network was decreased. This indicates that with the increase in the number of blockchain users of the Monero blockchain network, the block transaction rate decreases. As the results show, the first, second, and third blockchain nodes have mean block transaction rates of 43.29, 47.71, and 43.14, while the fourth, fifth, and sixth nodes have mean block transaction rates of 59.43, 47, and 46.29 blocks per second, respectively. Also, from node 7 to node 10, the mean block transaction of the network was recorded as

The blockchain nodes 11 to 15 have mean block transaction rates of 51.57, 49.71, 48, 47.14, and 48.14 blocks per second, respectively. Figure 17 shows the analysed results of the block transaction rate with twenty Monero blockchain nodes, and the results indicate that the block transaction rate deviates from 25 blocks per second to 50 blocks per second. We can highlight that compared to the fifteen-node blockchain network, there is a decrement in the block transaction rate when scaling up the blockchain network. Also, from the 1 st blockchain node to the 5 th blockchain node, the mean block transaction rates were recorded as 35.86, 31, 33.71, 39.14, and 38.14 blocks per second, while the mean block transaction rates of nodes from 6 to 10 were recorded as 30.86, 35.14, 28.71, 29 and 39 blocks per second. From the 11 th node to the 15 th node, the block transaction rates were recorded as 44.14, 32.43, 32, 30, and 31.43 blocks per second, while the mean block transaction rates of nodes 16 th, 17 th, 18 th, 19 th, and 20 th were noted as 34.14, 36.57, 41.43, 33.71 and 33.57 blocks per second, respectively. As the results in Figure 18 show, the block transaction rate of the seven-node Duino coin blockchain network deviated from 54 blocks per second to 64 blocks per second. The

Duino coin network recorded a lower block transaction rate than the Monero blockchain network. However, the Duino coin block transactions rate is higher than the Hydrachain block transaction rate. As per the results in Figure 18, the first blockchain node has a mean block transaction rate of 59.29, while the second and third nodes have mean block transaction rates of 60 and 58.86 blocks per second, respectively.
