Embodiment 1

[0026] A hot data sharing platform based on blockchain, please refer to the attached figure 1 , this platform includes: a synchronization node 10, a reservation node 20, a number of coordination nodes 30 and an access node 40, the synchronization node 10 and the reservation node 20 are all set at the data source side, and the synchronization node 10 obtains hot data synchronously from the data source side system Data, assign the row number 11 to the data row of the hot data, and the synchronization node 10 makes several copies of the data row, the copy is associated with the row number 11, and splits the actual value of the numeric field of the data row into several addends, several Addends are assigned to several copies respectively. Reserved node 20 reserves one copy as a reserved copy, and the remaining copies are allocated to several collaborative nodes 30 for storage. The real value of the non-numeric field is stored by the reserved copy, and the remaining copies store the...

Embodiment 2

[0051] A blockchain-based thermal data sharing platform, this embodiment is based on the first embodiment, and further expands from the neural network model for occasions where weighted sum calculations can be performed. Please refer to the attached Figure 5 , the calculation of the data processing model 50 in this embodiment includes the following steps:

[0052] Step B01) The synchronization node 10 calculates the real value of the numerical field and the value from the power of 2 to the power of N, and creates a new column of the power of 2 to the power of N for each numerical field in the copy;

[0053] Step B02) Divide the 1st power to the Nth power value of the real value of the numeric field into several addends, and assign them to the reserved copy and the remaining copies for storage;

[0054] Step B03) Before the reserved node 20 constructs secure multi-party computation, perform the following steps on the data processing model 50:

[0055] Step B04) Extracting a ...

Embodiment 3

[0075] A blockchain-based hot data sharing platform. Bank A, Bank B, and Supermarket C have respectively established synchronization nodes 10 and reserved nodes 20. Bank A and Bank B synchronize their depositors’ deposit data to Synchronization node 10, supermarket C synchronizes the consumption record of its membership card to the corresponding synchronization node 10.

[0076] Assume that the deposit data includes the name of the depositor, the ID number of the depositor, the mobile phone number of the depositor, the balance and the education background of the depositor, and the consumption data of the membership card of the supermarket includes the name of the member, the mobile phone number of the member, the membership level, the discount level and the credit limit. The supermarket's membership card is a real-name membership card for high-quality consumers. It has a relatively high discount and a certain credit limit, which can be used by consumers to pay first. Therefore...

Abstract

The invention relates to the technical field of block chains, in particular to a hot data sharing platform based on a block chain. The platform comprises a synchronization node, a reservation node, a plurality of collaborative nodes and an access node; the synchronization node acquires hot data, makes a plurality of copies, associates row numbers, splits a true value of a numeric field of a data row into a plurality of addend numbers, reserves one copy as a reserved copy, and distributes the other copies to the plurality of collaborative nodes for storage; the synchronization node periodically synchronizes the hot data, calculates the variable quantity of the numeric field and synchronizes the variable quantity into the corresponding reserved copy; a data demand side submits a data calling request to the access node; the reservation node and the plurality of cooperative nodes acquire a result of a data processing model, and send the result to the access node; and the access node sends the result to the data demand side. The platform has the beneficial effects that: the privacy security of the hot data is effectively protected, the timeliness of the data is improved, and the execution efficiency of the data processing model is accelerated.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a hot data sharing platform based on block chains. Background technique [0002] With the rapid and in-depth development of information technology, human society is transforming from an industrial society to an information society. A large number of enterprises and institutions enter a large amount of business data into the information management system in the form of data through the electronic office system. It not only allocates the human, financial and material resources of the enterprise more efficiently and reasonably, improves the utilization rate of production resources, but also forms a large amount of business data. Among them, according to the frequency of data use, data can be divided into hot data, warm data and cold data. Hot data refers to data that is frequently queried or updated. Cold data refers to extremely infrequent use, such as archived data. Cold ...
