[0078] S33, other nodes in the power dispatching blockchain network verify the data block (power dispatching instruction file) and its digital signature;

[0079] S34, after the data block (electric power dispatching instruction file) and its digital signature are successfully verified, the digital watermark of the dispatching responsible agency in the data block (electric power dispatching instruction file) is checked;

[0080] like Figure 4 and 6 As shown, in this step, the digital watermark is checked, and the specific method is as follows:

[0081] S341, extracting a digital watermark from a data block;

[0082] S342, performing extended Arnold transformation on the extracted digital watermark to obtain WA1 and WB respectively;

[0083] S343, compare and verify WA1 and WB. If the verification is successful, the digital watermark verification is correct.
