Claim 13:
14. A device for performing credit evaluation on a work publisher associated with a blockchain network comprising a plurality of service nodes, each service node having permission to publish works to the blockchain, the device comprising:
an originality analysis module configured to perform, 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, so as to obtain an originality representation value corresponding to the target work, wherein the target service node is any service node, and the originality representation value is positively correlated with a degree of originality of the target work;
a determination module configured to compare the originality representation value to a first specified threshold and determine a copyright credit score decrement or increment based on an outcome of the comparison and the originality representation value and based on a copyright credit score coefficient of the target service node, wherein the copyright credit score coefficient is determined based on a historical performance of the service node in publishing works with degrees of originality to the blockchain network;
a credit transfer creation module configured to create a credit deduction or addition transfer on the basis of a node identifier of the target service node and the copyright credit score decrement or increment, respectively;
a credit transfer broadcasting module configured to broadcast, by the respective service 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.
