When there is a need for data analysis or data query on the block chain, the data lake node 30 does not need to directly link the chain to query the data information on the block chain, and each application system only needs to directly query the block information synchronized from the chain according to the block data sharing service provided by the data lake.
Referring to fig. 6, the service system node 10 includes a service processing module 11, a service review module 12, and a broadcast blockchain module 13. Specifically, the method comprises the following steps:

And high-efficiency service processing and transmission are realized. After the on-chain data storage is completed, a data synchronization mechanism is triggered at the same time, and the on-chain service information is automatically packaged and pushed to the message middleware.
The message receiving module 22, after the message middleware receives the service message pushed up and down by the chain, stores the message in the message queue according to the first-in first-out rule.
And the data distribution module 23 automatically distributes and pushes the messages in the message queue according to preset push rules, and pushes the messages down to the data lake application server.
Referring to fig. 8, the data lake node 30 includes:
the data storage module 31, after receiving the message pushed down by the message middleware, interprets the data, converts the interpreted data into a DML operation statement, and then executes the DML statement to update the block data into the data lake.

The theme aggregation is composed of aggregation main key information, attribute information and dimension information, and information cohesion guarantees that requirements of upper layer data are met in a display mode of a small number of tables.
Primary key information: the minimum granularity of the description data record may be a joint primary key composition, such as a loan consisting of a loan account number + product + contract + loan data.
Attribute information: describing the characteristics of the data record object, and expanding the service elements which are possibly used subsequently at the granularity of the primary key as much as possible according to the application requirements.
Dimension information: the information may be summary information that is counted up by the data record object at a certain frequency or range, or information of a non-local level of granularity related to the record object. The goal is to precipitate according to the user concentration, and the information can support different requirements.
And the data sharing module 33 is used for packaging the theme aggregated data or the common block data generated by processing the front 32 modules and providing service modes comprising online interfaces, batch data services, flexible query, data services with interfaces, table call and the like. If each service system needs to perform big data analysis or statistical query on data on the block chain, data query statistics can be directly performed according to services provided by a data lake under the chain without uploading data.
In addition, this embodiment further provides a method for implementing block chain data sharing in the bank field by using the above modules, and the specific steps are as follows:

And step S2, the bank completes the examination and verification of the business data, completes the business transaction in the business system of the bank, and generates the text of the business-related confirmation.
And step S3, uploading the opened service text information to a block chain platform, and broadcasting to the block chain link points for consensus.
And step S4, the service intelligent contract processes and recognizes the uploaded service text and stores the data in the database on the block chain, and other systems connected to the block chain platform can efficiently and quickly acquire the information on the service chain from the block chain platform. And high-efficiency service processing and transmission are realized.
And step S5, after the data storage on the chain is completed, triggering a data synchronization mechanism, automatically packaging the service information on the chain, and pushing the service information to the message middleware.
Step S6, after the message middleware receives the service message pushed up and down by the chain, the message is stored in the message queue according to the first-in first-out rule.
And step S7, the message middleware automatically distributes and pushes the messages in the message queue according to preset pushing rules, and pushes the messages to the data lake server.
And step S8, after receiving the message pushed down by the message middleware, the service platform server interprets the data. And converting the interpreted data into a library DML operation statement, and executing the DML statement to update the data lake.
And step S9, performing patent processing such as theme aggregation on the data of the data lake region to generate a professional shared data service.
Step S10, if the business systems need to perform big data analysis or statistical query on the data on the block chain, the business systems do not need to search the data up, and can directly perform data query statistics according to the data sharing service provided by the data lake under the chain. The powerful engine and retrieval capability of the data lake under the chain are used for providing data convenient query and analysis capability for a data consumer, and meanwhile, the data access pressure on the block chain is reduced.
