基于区块链的学分信息上链模型及实现

Blockchain-based Credit Information Uplink Model and Implementation

学分银行作为重要的学分数据信息平台,应具有高度的权威性,学分银行系统数据安全尤为重要。传统的学分银行系统无法避免人为的删除、篡改等恶意操作,难以保证数据的安全性。区块链作为去中心化系统,是天然的数据存储平台,其以链表结构将数据关联,衍生了数据难以篡改特性。本文提出了基于区块链的学分信息上链模型,制定了数据序列化方法,解离数据类型与数据元素,以“协议+数据”模式,设计协议链码和批量上链的数据链码,实现了基于区块链的学分银行系统并进行了上链实验对比。实验结果表明,本方案可以有效保障学分银行系统数据的安全性,并且可以提升上链存证业务性能。

As an important credit data information platform,the credit bank should have a high degree of authority,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 elements,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.
