As an important credit data information platform,the credit bank should have a high degree of authori-ty,and the data security of the credit bank system is particularly important.The traditional credit banking system cannot avoid malicious operations such as manual deletion and tampering,and it is difficult to ensure the security of data.As a decentralized system,blockchain is a natural data storage platform.It associates data with a linked list structure and derives the characteristics that data is difficult to tamper with.This paper proposes a blockchain based credit information uplink model,develops a data serialization method,separates data types and data ele-ments,designs protocol chain codes and batch uplink data chain codes in the mode of"protocol+data",realizes a blockchain based credit banking system,and conducts uplink experiment comparison.The experimental results show that this scheme can effectively guarantee the security of the credit banking system data,and can improve the performance of the online certificate storage business.
