WCT Payment Function's On-chain Accounting System**
The WCT payment function in testing uses on-chain accounting, with each payment record permanently recorded on-chain, including payment amount, service type, timestamp, and other information, which users can query through the block explorer. This transparency in accounting avoids fee disputes and provides data support for the foundation to analyze service usage rates. During the testing period, 15,000 on-chain payment records have been generated, and data analysis shows that the 'Priority Connection' service has the highest usage rate (accounting for 60%), providing a decision-making basis for subsequent resource allocation, making the iteration of the WCT payment function more accurate.
