The invention belongs to the technical field of block chains, and particularly relates to a
data acquisition classification and grading maturity index
accounting method, a block
chain system and a
data acquisition classification and grading maturity evaluation method. The
data acquisition classification and grading maturity index
accounting method comprises the steps that firstly, an identification capability index and a management index in data acquisition classification and grading maturity indexes are obtained; based on the block
chain network, a
consensus request is initiated for the obtained identification capability index and the management index, signature is performed after
consensus is completed, uplink storage is performed on the identification capability index and the management index after
consensus is completed, and the obtained identification capability index and the management index are consensus through a block chain, so that the extracted maturity index is higher in credibility and higher in accuracy, and the fairness of an
evaluation result can be guaranteed. The identification capability index and the management index which are subjected to consensus are stored on the block chain, so that the identification capability index and the management index cannot be modified, the identification capability index and the management index can be called and used each time of evaluation, the identification capability index and the management index do not need to be additionally established, and the evaluation
workload is greatly reduced.
