In this paper, the issue of financial credential asset tokens is studied in the context of blockchain technology. In order to solve the problems of large file storage and poor algorithm performance in current research on financial credential asset token, based on the blockchain technology, the data of the business system can be protected. Then, by packaging the contents of financial credentials into blocks, the malicious tampering of financial credentials by operators is effectively prevented. There are two innovations. First, by using electronic storage technology of financial credentials, which combines distributed file system and blockchain, the problem that each transaction message on the current blockchain is not suitable for carrying large file attachments can be solved. Second, a new algorithm CT-DPCFT is innovatively proposed to improve the performance of consensus algorithm. Thus, the financial credentials can be packaged on the chain in a lightweight manner, and consensus discrimination can be carried out efficiently at the business side. The experiment results show that CT-DPCFT can solve the problems of difficult storage of large files and poor algorithm performance of current financial credential asset tokens to some extent.
