step S601: the block link point device receives first item information and a digital signature from the management terminal.
In one implementation, the block link node device may receive first item information and a digital signature from the management terminal, the first item information may include an item identifier of the target item and an evaluation grade of the target item, and the digital signature may be generated by the management terminal by encrypting the first item information using a private key of the management terminal. The evaluation grade of the target project can be granted by an international authoritative credit worthiness evaluation organization, and the credit worthiness evaluation organization predicts the target income of the virtual resource of the target project through feasibility research on the target project and grants the corresponding evaluation grade of the target project according to the prediction result.
