Data cross-blockchain access control method and system in multi-blockchain scene, equipment and terminal

Abstract

The invention belongs to the technical field of data access control, and discloses a data cross-blockchain access control method and system in a multi-blockchain scene, equipment and a terminal. The data cross-blockchain access control method in the multi-blockchain scene comprises a registration stage, data uploading, data uploading, data access, access record uploading and data acquisition. According to the method, the data cross-blockchain access control requirement in a multi-blockchain scene can be met, and a cross-blockchain access control scheme is provided for solving the insufficient performance and capacity of a blockchain technology in a single-blockchain architecture and the problem that a traditional technology cannot meet or realize asset exchange and information exchange requirements of a complex cross-blockchain service. According to the method, asset exchange, data sharing and contract calling among heterogeneous blockchains in a multi-blockchain scene are allowed; the architecture can be flexibly organized and deployed according to scene guidance, and the method has core function characteristics of a general cross-blockchain transmission protocol and a heterogeneous transaction verification engine, and provides reliable underlying technical support for service blockchain service security management and blockchain Internet formation.

Description

technical field [0001] The invention belongs to the technical field of data access control, and in particular relates to a data cross-chain access control method, system, device and terminal in a multi-chain scenario. Background technique [0002] At present, the current blockchain applications and underlying technology platforms are in a state of blooming, but each chain in mainstream blockchain applications is still mostly an independent, vertical closed system. In commercial application scenarios with increasingly complex business forms, there is a lack of a unified interconnection mechanism between chains, which greatly limits the liquidity of digital asset values ​​on the blockchain, and the demand for cross-chain arises from this. [0003] Cross-chain refers to the realization of trusted interoperability of different ledgers by connecting relatively independent blockchain systems. Cross-chain can be roughly divided into digital asset exchange and information exchange ...

AI Technical Summary

Problems solved by technology

[0006] (1) The centralized exchange method is neither safe nor transparent

[0007] (2) Most of the current decentralized asset transactions can only realize the exchange of different contract assets on the same blockchain, and the decentralized exchange of cross-chain digital assets is still not perfect, and in fact they are still in a state of isolation from each other

[0008] (3) Information exchange is more complicated because it involves data synchronization between chains and corresponding cross-chain calls, so the intercommunication barriers between each blockchain application are extremely high, and information sharing on the chain cannot be effectively carried out

[0009] (4) The blockchain technology itself has problems such as poor performance and insufficient capacity under the single-chain architecture. The single-chain is limited by the balance of decentralization, scalability, and security, and it is difficult to support high transaction throughput and low latency. Business Scenario Application

[0010] (5) As the running time of the blockchain increases, its storage capacity will gradually increase, and the data growth rate will even exceed the upper limit of the capacity of the single-chain storage medium, which greatly limits the healthy development of blockchain technology

[0012] (1) The problem of verification of cross-chain transactions, how to confirm that the block that records the transaction has been confirmed enough, that is, the data consistency problem among the distributed networks in the transaction transaction;
