Table 2 MPT-Chain

From: A blockchain index structure based on subchain query

Number of blocks	Query time/ms	AVG	Mean deviation
1000	15 21 18 12 16 19 22 18	17.6	19.8
2000	38 34 31 39 29 45 41 39	37.0	34.0
3000	53 58 45 56 49 44 39 51	49.4	41.0
4000	63 56 62 53 51 64 66 65	60.0	40.0
5000	78 73 85 81 76 75 77 75	77.5	23.0
6000	82 89 87 87 92 83 93 86	87.4	23.8

The subchain length k is 10, and AVG is the average query time
