And 102, carrying out statistical processing on the obtained transaction hash values, and clustering the same transaction hash values.
Illustratively, the same transaction data corresponds to a unique transaction hash value, all transaction hash values obtained from the probe nodes are subjected to statistical processing, and the same transaction hash values are clustered to obtain a plurality of clustering results.
Illustratively, the probe node records and stores the transaction hash value of the received transaction data in association with the broadcast IP address from which the transaction data was broadcast.

When the target broadcast IP address corresponding to the transaction hash value in any clustering result is determined, an acquisition instruction containing the target broadcast IP address or identification information of the target broadcast IP address can be sent to the probe node, so that the probe node sends the associated and stored receiving time to the originating IP address determination device according to the information of the target broadcast IP address contained in the acquisition instruction, and the receiving time of the probe node receiving the transaction data corresponding to the transaction hash value from each target broadcast IP address is obtained.

(2) if 5s < t < 6s, the probability that the target broadcast IP address is the transaction originating IP address is p 2;
(3) if 6s < t < 7s, the probability that the target broadcast IP address is the transaction originating IP address is p 3;

For example, when the number of transaction hash values included in any clustering result is less than a preset threshold, it indicates that the transaction data occurs less frequently, that is, the transaction data is sparse data, the transaction data corresponding to the transaction hash value may still be in a broadcast state, and for the transaction data occurring less frequently, the operation of determining the transaction originating IP address in response to the transaction is stopped. The preset threshold is not limited in the embodiment of the present application, and a person skilled in the art can determine the preset threshold according to actual needs, and the preset threshold in the embodiment of the present application may be 10.
As an alternative embodiment of the present invention, after step 105, the method further comprises: randomly generating a user ID for each clustering result; generating triple data corresponding to the clustering result, wherein the triple data comprise: a user ID, a transaction originating IP address, and a probability value corresponding to the transaction originating IP address.
