Description
Technical Field
The present invention relates to the field of blockchain technologies, and in particular, to a middlebox-based blockchain data transmission management method and system.
Background
Currently, in a large complex service system, a complex service logic and a large amount of network communication data traffic are generally required for a block chain scenario. In this context, typically a portion of the data is uplinked, or hashed uplink, while a majority of the data is not uplinked. When the traditional distributed storage system or database storage is adopted, a middle station server cluster for processing service logic is indispensable, so that a scheme of adding a block chain to a middle station is formed.
Since the blockchain is completely decentralized and only the user has the operation authority of the related data on the chain, all the development kits provided by blockchain manufacturers are also directly directed to the client. However, transmission in the internet is not secure, and in order to improve transmission security, there are three general solutions:
the first, complete decentralized scheme, namely the client side directly operates the block chain, and all complex business logic is realized on the intelligent contract chain. The performance of the scheme is constrained by the performance of a block chain main network, and the scene is limited, so that the client requirement of the current internet service scene cannot be met.
And secondly, the client is a center, on one hand, a client operation block chain submits data on the chain, on the other hand, the client initiates an instruction to the server, and the high-concurrency service cluster performs service logic processing. On one hand, the performance of the scheme is influenced by the main network performance of the block chain, and on the other hand, the transaction consistency is difficult to guarantee.
And thirdly, the client accesses the middle station, the middle station performs service logic processing, the middle station allocates an account for the user, and a block chain account mapping relation is established for the user in a middle station database. The client submits the service instruction to the service server central station cluster, and the central station cluster performs data uplink instead of the user after complex service logic processing. The method has the advantages of high performance, reliability, transaction consistency and the like which can be effectively solved. Is also the preferred scheme of many large-scale complex business systems at present.
However, such a solution has a serious problem that it breaks the root of trust of the block chain, and the authority of data on the chain is moved from the user end to the middle service cluster. In addition, according to the account mapping scheme, once the middle database is attacked, all the information on the user chain is attacked, all the data management rights on the chain are completely transferred to an attacker, and potential safety hazards are introduced.
