Problems solved by technology

However, this technology is still in its infancy, and there are problems such as high consumption and low efficiency, privacy leakage and lack of responsible subjects.
In addition, if this model is adopted, the bank will lose the central position of the system, and it will be more difficult for the government to implement supervision and cannot guarantee the safety and controllability of the financial system
At present, the virtual currency represented by "bitcoin" is a typical representative of blockchain in financial

Example Embodiment

[0059] Example 1

[0060] This embodiment provides a weakly centralized trusted data management method of the total score double chain of a digital bank. First, the weakly centralized trusted data management system of the total score double chain of the digital bank of the present invention uses asymmetric encryption technology to Identify identity and ensure security, that is, depositors and banks have their own private and public keys, and use digital signatures to authenticate identity and achieve non-repudiation of information. For example, depositors use digital signatures to ensure the authenticity of transaction requests, and banks use digital signatures to ensure the authenticity of system messages and transfer receipts. At the same time, similar to the registration mode of virtual digital currency such as Bitcoin, there is no so-called centralized CA institution (ie, "certificate authority") in the digital banking system. The key pair of the depositor is generated by the...

Example Embodiment

[0088] Example 2

[0089] This embodiment provides a weakly centralized and trusted data management system for the total score of a digital bank using the method for managing the total score of the digital bank in the first embodiment of the double chain, such as Image 6 Shown, including: client and server connected through the network;

[0090] The client includes: a client storage module and a request module;

[0091] The client storage module is used to store the block header chain of the BC chain and its own account chain;

[0092] The request module is configured to send an inspection request to the server according to;

[0093] The server includes: a central storage module and an account management module;

[0094] The central storage module is used to store complete transaction flow, account data, BC chain, and account chain data of each depositor;

[0095] The account management module is configured to return the Merkel path of the corresponding block and the overall transaction...

Abstract

The invention discloses a weakly centralized and trusted data management system and method of a total-score double-chain of a digital bank. The method comprises the following steps of interweaving alltransaction flowing water into a directed transaction network according to the transaction subject and the transaction time; cutting the directed trading network into a general ledger chain and a plurality of account-by-account ledger chains from horizontal and vertical directions respectively; synchronously consolidating the header information of all the sub-ledger chains into a block of the general ledger chain, thereby consolidating the general ledger chain and the sub-ledger chain into a BC chain; inspecting the relevant transaction and account information through chain head verificationand transaction verification to ensure the authenticity of the inspection information. The total-division double-chain structure is adopted, on the premise of maintaining the centralized storage and management of data, the center ensures that the data is open and transparent, has the characteristics of non-tampering and traceability of block chain, and enables all depositors to be supervisors, indirectly auditing the overall accounting data of the system, thereby avoiding the possibility of bank tampering with data and bookkeeping false accounts.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a weakly centralized and trusted data management system and method for a total score double chain of a digital bank. Background technique [0002] The traditional banking system has long adopted the "centralized" management model, which has the advantages of high efficiency, controllability, and convenient management. However, in recent years, with the disclosure of some insider crimes and external attacks, the disadvantages of the centralized model have become increasingly prominent: centralized Storing all account information and transaction information can easily become the target of hacker attacks and cause huge losses. More importantly, centralized management lacks transparency and supervision. Depositors can only passively trust the bank completely, and it is difficult to actively implement supervision. Banks have the right to record every transaction, and have the...
