[0098] V 100-1 , V 100-2 , V 110-1 , V 110-2 The start speed of the same as A, according to the sequence of data generation time, from V 100-1 Point to V 100-2 , By V 110-1 Point to V 100-2 , By V 110-1 Point to V 110-2;

[0099] In this embodiment, the data processing module 45 is involved in processing different types of data of different blockchains:

[0100] V j-1 Is V 100-2 And V 110-2 As the input value, the relevant physical ability value of A is calculated according to the provisions of the "National Student Physical Health Standard". The direction is from the input value to the output value, that is, from V 100-2 And V 110-2 Point to V j-1;

[0101] This embodiment does not involve the relationship between numerical changes and application processing procedures between different types of data of the same blockchain.

[0102] Due to the irreversibility of the timestamp of each blockchain and the uniqueness of the blockchain data, starting from any node and passing through different routes, it is impossible to return to this point, so the graph data structure is a directed acyclic graph .

[0103] Complete the drawing of directed acyclic graph.
