Claim 26:
27. A computer apparatus, comprising a memory, a processor, and a computer program stored on the memory and executable by the processor, wherein the processor executes the program to perform a acts of performing credit evaluation, the acts comprising:
deploying a blockchain network including a plurality of service nodes each service node having permission to publish works to the blockchain network, each service node of the plurality of service nodes being assigned a copyright credit score coefficient based on a historical performance of the service node in publishing works with degrees of originality to the blockchain network;
performing, by a respective service node in the blockchain network, originality analysis, according to published works in the blockchain, on a target work published by a target service node to the blockchain network, so as to obtain an originality representation value corresponding to the target work, wherein the target service node is any service node, and wherein the originality representation value is positively correlated with a degree of originality of the target work;
comparing the originality representation value to a first specified threshold and determining a copyright credit score decrement or increment based on an outcome of the comparison and the originality representation value;
constructing a credit deduction or addition transfer based on a node identified of the target service node and the copyright credit score decrement or increment, respectively;
broadcasting, by the respective node, the credit deduction or addition transfer to the blockchain network, such that a plurality of service nodes in the blockchain network, upon successful consensus verification of the credit deduction or addition transfer, establish a corresponding relationship between the node identifier and the copyright credit score decrement or increment, respectively, and store the corresponding relationship in a blockchain; and
wherein a copyright credit score corresponding to the target service node is positively correlated with credit evaluation of a user corresponding to the target service node.
