System architecture for cross-block-chain open data sharing under heterogeneous multi-chain architecture

Abstract

The invention provides a system architecture for cross-block-chain open data sharing under a heterogeneous multi-chain architecture. The system architecture comprises (1) an application layer, including an OpenData module, an intelligent contract module, a multi-account-book query module and a data analysis module; (2) a multi-chain protocol, including a cross-chain transmission protocol applied to a transaction standard and a transmission mode, a cross consistency protocol applied to transaction confirmation and transaction feedback, a heterogeneous block chain cross-chain data communicationand transaction protocol, routing management applied to gateway management and number management, and a multi-chain management strategy applied to longitudinal management and transverse management; (3) a middleware layer applied to transactions and query outside block chains and synchronous keys inside the block chains for establishing blocks and achieving voting and broadcast functions; (4) a basic block chain layer, including Fabric, Ethereum, Bitcoin and Corda; and (5) a basic platform layer based on a cloud environment and a virtual machine. The system architecture helps a user to securelyshare data and service provided by a third party, and the problem of "data splitting" is solved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to the interconnection technology based on heterogeneous block chains to realize safe, credible, open and shared data across institutions. Background technique [0002] Data silos are a loss to society as a whole. For example, you have a deposit in ICBC, you buy a house with a loan from Ping An Bank, you trade stocks in CITIC Securities, and you also have a credit card from China Merchants Bank. Individuals are producers and owners of financial transaction data, and these four financial institutions are data custodians. However, due to different financial institutions, the data of the same individual is fragmented. Since data has important commercial value for organizations, they will not easily open it up to the outside world. [0003] For example, in the financial industry, the non-openness of financial data will have some impact on all parties. For individuals, t...

AI Technical Summary

Problems solved by technology

[0007] 1. Inter-agency data connectivity issues and data interaction speed issues;

[0008] 2. Data quality problems of source data, data integrity and authenticity cannot be guaranteed;

[0009] 3. User data privacy issues; privacy data leakage and abuse

[0010] The use of blockchain technology can well protect the privacy of data and provide a verification mechanism for data integrity and authenticity. However, the blockchain currently faces problems such as poor storage performance, limited scale, and no unified standards.
