The contract upload smart contract processes the store cooperation contract into a contract block based on the text segmentation encryption algorithm. The contract block contains the blockchain address of the store server. The contract upload smart contract sends the contract block to the parent company server and the store nature identification smart contract. The parent company server sends the contract block to the blockchain network and the general ledger.

[0008] Furthermore, the store server, regulatory server, and parent company server all serve as nodes in the blockchain network and follow the blockchain consensus mechanism of the blockchain network.

[0009] Furthermore, the store nature table block includes a store nature table that records the store name, store nature and parent company equity information.

[0010] Furthermore, the nature of the stores includes holding stores and non-holding stores.

[0011] Furthermore, the store system also includes a reminder smart contract, and the reminder smart contract is communicatively connected to the store server.

[0012] Furthermore, the report verification and scoring smart contract verifies and scores the store report block in step A: Step A1: The report verification and scoring smart contract receives the store report block; Step A2: the report verification and scoring smart contract extracts the store financial report text content of the store report block based on the extraction function; Step A3: The report verification and scoring smart contract uses the financial audit software to identify whether the data in the store's balance sheet, income statement, and cash flow statement are missing; Step A4, if yes, the report verification and scoring smart contract generates a correction block recording the missing content. The correction block contains the blockchain address of the store server that sends the store report block. The report verification and scoring smart contract sends the correction block to the supervision server. The supervision server sends the correction block to the store server with the corresponding blockchain address through the blockchain network. The store server sends the correction block to the store account book and the reminder smart contract. The store account book stores the correction block. The reminder smart contract extracts the content of the correction block based on the extraction function and sends it to the user through the user interface. Step A5: If the answer is no, the report verification and scoring smart contract extracts the store financial report content of the store report block based on the extraction function; The report verification scoring smart contract calculates the store operation score B based on the net profit margin L, return on net assets Q and debt-to-asset ratio V in the financial statements, and uses the following formula: B = (L + Q) / V; Step A6: The report verification and scoring smart contract processes the store operation score B into a scoring block based on the file segmentation encryption algorithm and sends it to the business evaluation smart contract.
