摘要/Abstract

摘要：

使用区块链技术可以保证数据资产管理的高安全性、高隐私性以及可追溯性等。通过对当前基于区块链的数据资产管理机制进行深入研究，总结得出当前管理机制只针对区块链体系框架中的某一层进行应用的结论。为了解决这一问题，提出了基于区块链技术的数据资产管理新模式，对区块链体系中的各个层次进行结合应用。该模式在网络层增加了节点权限控制机制，在共识层实现了共识机制可自定义属性，在数据层通过优化结构和建立索引来提高数据查询效率，在智能合约层实现了数据智能化管理和共享，在交易层实现了可自定义加密算法的信息加密。实验结果表明，相比于传统模式，基于区块链技术的数据资产管理新模式在链上数据查询效率上提升了2.33倍。

Abstract:

The blockchain technology can ensure the high security, high privacy and traceability of data asset management.Through research on the current blockchain-based data asset management mechanism, it is concluded that the current management mechanism is only applied in a certain layer of the blockchain framework.In order to solve this problem, a new mechanism of data asset management based on blockchain was proposed.The mechanism combined and applied all layers in the blockchain framework.In addition, this mechanism added a node authority control mechanism at the network layer, realized the consensus mechanism with customizable attributes at the consensus layer, optimized the structure and built indexes to speed up data query efficiency at the data layer, realized intelligent data management and sharing at the smart contract layer, and realized information encryption with customizable encryption algorithms at the transaction layer.Experimental results show that the new mechanism of data asset management based on blockchain improves the efficiency of data query on chain by 2.33 times compared with the traditional mechanism.
