OKX Blockchain 101 | Episode 53: What Is a Blockchain Invoice?
Hello everyone, I'm Xiao K. Today we'll be talking about: "What Is a Blockchain Invoice?"
A blockchain invoice is a type of electronic invoice issued using blockchain technology, and it differs significantly from traditional invoices. Our conventional invoices, whether paper or electronic, require businesses to purchase their own royalty control equipment or outsource to third-party service providers just to issue an invoice.
However, this approach has several drawbacks. First, data is not shared between parties. Since each enterprise builds its own platform, the sheer number of systems and the complexity of the equipment creates significant barriers to data sharing and circulation. As a result, each invoice is difficult to track and verify, leading to long reimbursement cycles and cumbersome processes.

Second, the lack of data sharing leads to another problem: invoice fraud and duplicate reimbursements. Traditional invoice anti-counterfeiting relies on tax authority-issued serial numbers with electronic signatures. Combined with the difficulty of quickly implementing paperless online reimbursement in batch verification systems, duplicate reimbursements and even counterfeit invoices have become a serious issue.

Third, building an invoice system also comes with costs, placing a significant burden on small and micro enterprises.

Blockchain invoices work differently. The state essentially builds an invoice system using blockchain technology, allowing participants in the blockchain network to take part without needing to establish trust relationships. Small and micro enterprises don't need to purchase equipment to issue invoices, saving on hardware expenses.
Additionally, blockchain invoices solve the problems of counterfeiting and difficult reimbursement at the source. In a traditional invoice system, the reimbursement process is: user completes consumption → issues a paper invoice → user requests reimbursement → system queries information → reimbursement completed. Throughout this process, most actions are carried out offline, making it extremely difficult to trace an invoice's origin, verify its authenticity, or check its accounting status. Blockchain invoices are different — since everyone's consumption data is recorded in the blockchain system, as soon as you make a purchase, the system automatically issues you a corresponding invoice, which you can claim through the WeChat portal. This skips all the offline steps and fundamentally solves the problems of counterfeiting and difficult reimbursement.

Beyond this, because blockchain invoices use blockchain technology, the data is shareable, traceable, and immutable. This makes it easy to query the origin and accounting information of every single invoice, significantly shortening review and reimbursement cycles. Therefore, blockchain invoices represent one of the most significant real-world applications of blockchain technology today.
Regarding the current adoption of blockchain invoices: as early as 2018, Tencent launched the first pilot program in Shenzhen. As of the first half of this year, nearly 20,000 enterprises have registered, with a total of over 25 million invoices issued and cumulative amounts exceeding 25.9 billion yuan — truly solving the problem of difficult reimbursement.
This technology is steadily advancing across the country, and before long, it will become an integral part of our daily lives. Let's look forward to that together.
