The terminal 10 first obtains information such as the signal strength of the current communication environment before reporting the blockchain data each time, so as to avoid reporting the blockchain data in a communication environment with poor signal, resulting in slow data transmission and data transmission. Incompleteness and so on.

S702. The terminal determines whether to acquire the location of the terminal according to the signal strength.

Specifically, the acquisition module 12 of the terminal 10 re-acquires the signal strength after a preset time when the signal strength is less than or equal to the preset value; and acquires the location of the terminal 10 when the signal strength is greater than the preset value.

Considering that the location of the terminal 10 will change with the location of the user, at this time, the communication environment where the terminal is located also changes in real time. Therefore, when the terminal 10 judges that the signal strength is less than or equal to the preset value, it judges that the current communication environment is not suitable for blockchain data reporting, caches the data in the terminal 10, and periodically obtains and judges the signal strength of the communication environment.

When the signal strength is greater than the preset value, the terminal 10 determines that the current communication environment is good and suitable for reporting the blockchain data. At this time, the terminal 10 obtains the location of the terminal 10 . Exemplarily, the location of the terminal 10 may be the latitude and longitude coordinates of the terminal 10 .
