The method comprises the following steps: the block chain link point receives a preset financial data authorization request sent by a sending end, wherein the preset financial data authorization request comprises financial data identification information and user identification information; and the block link point returns first authorization information to the sending end according to the financial data identification information and the user identification information, wherein the first authorization information comprises a decryption key and authorization time of the preset financial data.)

1. A method for processing big financial data in a block chain is characterized by comprising the following steps:

the block chain link point receives a preset financial data authorization request sent by a sending end, wherein the preset financial data authorization request comprises financial data identification information and user identification information;

and the block link point returns first authorization information to the sending end according to the financial data identification information and the user identification information, wherein the first authorization information comprises a decryption key and authorization time of the preset financial data.

2. The method of claim 1, further comprising:

the block chain link point determines user authorization information corresponding to the financial data identification information and the user identification information according to the financial data identification information and the user identification information;

generating second authorization information according to the user authorization information, wherein the second authorization information comprises a decryption key of the preset financial data;

and returning the second authorization information to the sending end so that the sending end can decrypt the preset financial data according to the decryption key and check the corresponding financial data content.

3. The method of claim 2, wherein the first authorization represented by the first authorization information is a temporary authorization; and the second authorization represented by the second authorization information is a formal authorization.

4. The method of claim 3, wherein the authorization time of the temporary authorization is a validity time of the decryption key.

5. The method according to any one of claims 1 to 4, further comprising:

and receiving a user authorization information writing request sent by the sending end, and writing the user authorization information into the block chain node.

6. The method of claim 5, wherein the predetermined financial data includes at least one or more of deposit data, fund data, stock data, bond data, insurance data, and trust data of the user.

7. The method of claim 6, wherein the financial data identification information comprises a financial data content identifier and/or a financial data content key identifier; the user identification information is a user ID and/or a device ID.

8. A blockchain financial big data processing system, comprising:

the client is used for sending a preset financial data authorization request; wherein the preset financial data authorization request comprises financial data identification information and user identification information;

and the block chain node is used for receiving and analyzing the preset financial data authorization request, and returning a first authorization to the sending client according to the financial data identification information and the user identification information, wherein the first authorization comprises a decryption key and authorization time of the preset financial data.

9. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the blockchain financial big data processing method according to any one of claims 1 to 7.

10. An electronic device, comprising:

a processor; and

a memory for storing executable instructions of the processor;

wherein the processor is configured to execute the steps of the blockchain financial big data processing method according to any one of claims 1 to 7 through executing the executable instructions.
