摘　　要：针对传统银行系统的中心化数据存储模式高效便捷但不透明、而新兴的去中心化的应用系统公开透明但共识机制低效的问题,提出了一种面向银行系统的总分双链的弱中心化可信数据管理方案。该模式的核心思想是应用区块链技术打造彼此交叉且相互印证的总分双链的数据存储结构,并利用分户账回溯定位技术,结合大量轻客户端基于密码学技术的分布式监督为个体提供交易验证的可能,从而实现数据的中心化可信存储与管理。它将中心化的数据存储与去中心化的数据验证相结合,从而兼有中心化管理的高效性和分布式机制的透明性,其本质上是一种民主监督下的中心模式,在满足银行独立,完全掌控数据的同时能够自证清白,并兼顾隐私与监督之间的平衡。Given the fact that the centralized data storage schema of traditional banking system is efficient but non-transpa-rent,while the emerging decentralized data management system is transparent but inefficient in the consensus mechanism,this paper proposed a new trusted data management schema with a cross binary-chain for general ledger and subsidiary ledger in a semi-centralized architecture.The core idea of the new schema was to build a cross-chain for the transaction data with the blockchain technology,so as to realize centralized trusted storage and management of data by combining the ledger backtrac-king location technology and the distributed supervision of a large number of clients based on cryptography technology.Combining the centralized data storage mode and decentralized data validation method,it is both efficient and transparent.Essentially,the cross binary-chain schema is a centralized approach based on distributed democratic supervision,which achieves the balance between privacy and supervision and satisfies the need for banks to independently and completely control over the transaction data.
