Problems solved by technology

The evaluation factors of the credit evaluation methods provided by the existing online trading platforms are relatively simple, and the evaluation mainly uses factors such as transaction volume
However, under the premise of profit-seeking, some sellers have adopted illegal operations such as false transactions, such as artificially manufacturing orders to increase transaction volume, thereby falsely increasing credit value
The above methods of falsely increasing the credit value can cause the existing evaluation system of the online trading platform to be untrustworthy, and it is impossible to make a relatively objective credit evaluation of the seller
