Can the Issue of Invoice Reimbursement in China be Solved Completely through the Integration of Blockchain and IoT Technology?

In order to achieve the automatic and non-inductive reimbursement of invoices and eliminate the various inconveniences as well as risks caused by artificial reimbursement, this paper creatively combines blockchain technology with electronic invoices. This system realizes interactive flows of paperless invoice for each node from consumption, reimbursement to tax payment through the blockchain network system. Based on the Internet of things technology, the off-chain data can be automatically processed and connected to the on-chain seamlessly. Meanwhile, using a dual-chain structure ensures the subsequent identification and business separation. Through the combination of theory and technical framework, the non-inductive invoice reimbursement system is constructed to reduce the overall reimbursement costs and promoting the improvement of the taxation system in China.
