WCT Payment Function On-Chain Invoice Verification System**
The WCT payment function has integrated an on-chain invoice verification system during testing. Electronic invoices generated by enterprise users are stored on-chain, allowing authenticity to be verified through block hashes, solving the issue of traditional invoices being easily tampered with. After implementation by a multinational corporation, the efficiency of financial audits increased by 60%, and the risk of false invoices was reduced to zero. The system also supports tax authorities for querying, meeting compliance requirements, and eliminating financial trust barriers for the promotion of WCT payment in the enterprise market.
