In the current embodiment, an execution subject of the technical solution provided by the present application is an operator node, and the method provided by the present application includes steps S210 to S250.
S210: and selecting a target bid evaluation party node and a target verification party node for the current bid inviting project from the evaluator information base.
In the technical scheme provided by the application, the information of a plurality of evaluator nodes is stored in the evaluator information base, the information of the evaluator nodes at least comprises identity identification information and point information of the evaluator nodes, and the point information is an index which is obtained by scoring of each verifier node in each evaluation process and is used for representing the service capability of the evaluator nodes. In the technical scheme provided by the application, an evaluator node for evaluating the bidding document is defined as a target evaluator node, and an evaluator node for verifying the evaluation result is defined as a verifier node. The evaluator information base may be stored in the operator node. In another embodiment, the evaluator information base may also be stored in other nodes or alliance block chains in the alliance block chain, and the operator node may further obtain information of each evaluator node in the evaluator information base by accessing the alliance block chain, and then select a target evaluator node and a verifier node for the current bid offering project based on the obtained information of each evaluator node.
When the evaluation is carried out, firstly, a target evaluation target node and a verification target node are selected for the current bid inviting project from an evaluation target information base. It should be noted that after any evaluator node is selected as the target evaluator node, the evaluator node may be configured to evaluate the candidate bid to obtain an evaluation result according to a set evaluation rule; when the evaluator node is selected as the verifier node, the evaluator node may be a target evaluator node and a verifier node which are used for verifying the evaluation result obtained by the evaluator node to obtain a verification result, and the same evaluator node cannot be simultaneously selected as the same bidding project. The set evaluation rule can require the operator node to evaluate the candidate tender based on a preset scoring factor so as to obtain an evaluation result. Wherein, the scoring factor includes: at least one of a bid amount of the bidder, a project plan of the bidder, a registered capital of the bidder, a development strength of the bidder, a financial status of the bidder, a project reputation score completed by the bidder, a performance of the bidder, a service of the bidder, and a response time of the bidder. It is understood that the scoring factor may be set according to actual requirements, and is not limited herein.
Further, in another embodiment, when there are multiple bidding items in the federation blockchain that need to be evaluated, the same evaluator node may be simultaneously selected as the target evaluator node and the verifier node of different bidding items. If two bidding items a and b without direct interest relationship need to be bid, the same evaluator node can be selected as the target bid evaluation node of the bidding item a and can also be selected as the verifier node of the bidding item b.
S220: and respectively sending the bid evaluation signaling to each target bid evaluation node and each verification party node.
After selecting a target evaluation party node and a verification party node for the current bidding project in the self-evaluation party information base, the operator node respectively sends evaluation signaling to each selected evaluation party node and each verification party node, so that the target evaluation party node evaluates the candidate bidding documents, and meanwhile, the verification party node verifies the evaluation results of the target evaluation party node. The bid evaluation signaling sent to the target bid evaluation node at least comprises the following steps: the information of the selected target evaluation party node and an instruction for starting evaluation on the candidate tender are obtained; the evaluation signaling sent to the verifier node at least comprises the following steps: the system comprises a notice of self being selected as a verifier node, information selected as a target reviewer node and an instruction for starting an evaluation result and/or verifying and evaluating the target reviewer node. And after receiving the bid evaluation signaling, the verifying party node responds to the bid evaluation signaling to obtain an evaluation result and verifies each evaluation result obtained by the target bid evaluation party node so as to obtain a verification result corresponding to each evaluation result.
Further, in order to make the evaluation of the candidate bidding documents and the verification of the evaluation result more fair and objective, the bid evaluation signaling received by each target bid evaluation node only includes the information of the candidate bidding document selected as the target bid evaluation node and the information of each candidate bidding document to be evaluated, that is, in the current embodiment, the bid evaluation signaling received by each target bid evaluation node does not include the information of other candidate bidding documents selected as the target bid evaluation nodes, and the bid evaluation signaling received by the verification party node includes the information of each target bid evaluation node.
Further, in order to make the bid evaluation process more fair and objective, in the current embodiment, in the technical scheme provided by the present application, information of the target bid evaluation node and information of the verifier node included in the bid evaluation signaling sent to the target bid evaluation node are both identification information corresponding to each evaluator node. When the identity information corresponding to each evaluator node is added to the alliance block chain for each evaluator node, the identity information of each identification node is distributed by the operator node, and has uniqueness in the alliance block chain.
S230: and receiving the evaluation result of the target evaluation party node responding to the evaluation signaling to the candidate bidding documents and the verification result of the verification party node responding to the evaluation signaling to the evaluation result.
After each target bid evaluation party node evaluates the candidate bid to obtain an evaluation result, the obtained evaluation result is further fed back, so that the operator node can obtain the evaluation result; after the verifier node verifies the evaluation result and obtains the verification result, the verifier node feeds back the verification result so that the operator node can obtain the verification result. Specifically, the target evaluation target node may uplink and store the evaluation result, so that the operator node obtains the evaluation result by accessing the federation block chain.
It is understood that, in other embodiments, the target bid evaluation node and the target verifier node may also directly send the evaluation result and the verification result to the operator node respectively, so that the operator node obtains the evaluation result and the verification result.
Wherein, the verification result comprises: and (4) scoring the authority verification result of the target evaluation party node and/or the service of the target evaluation party node.

In another embodiment, the verifier node may also be configured to verify whether an evaluation result obtained by evaluation of the target bid evaluation node meets a preset evaluation rule, score the service of the target bid evaluation node according to the evaluation result obtained by the verification, and feed back the score of the service of the target bid evaluation node as a verification result to the federation block chain.
Further, when feeding back the evaluation result, the target bidder node may mark the candidate tender book corresponding to the current evaluation result in the evaluation result, and similarly, when feeding back the verification result, the verifier node may mark the target bidder node and the candidate tender book corresponding to the verification result correspondingly, so as to facilitate the operator node.
S240: and determining the final score of each candidate tender according to the evaluation result and the verification result.
And after receiving the evaluation result and the verification result, the operator node further determines the final scores of the candidate posters. And the final score is a scoring result which is obtained according to the received evaluation results and the verification results and is used for representing whether the candidate tender is tender for the project.
S250: based on the final scores of the candidate bids, a target bid for the current bid item is determined from the candidate bids.
After determining the final scores of the candidate bidding documents according to the evaluation result and the verification result, determining the target bidding document of the current bidding project from the candidate bidding documents based on the final scores of the candidate bidding documents. The number of the target bidding documents is not limited, and is not limited herein specifically according to actual requirements.
In one embodiment, when only one target tender needs to be selected for the bidding project, the operator node determines the candidate tender with the highest final score as the target tender based on the final scores of the candidate tenders.
In another embodiment, when a set number of target bids need to be selected for the bidding project, the candidate bids may be sorted from high to low according to the final score, and the set number of candidate bids ranked at the top of the final score may be determined as the target bids. Wherein the set number is greater than 1. It is understood that in other embodiments, the target bidding document may be determined according to other rules, which are not listed herein.
In the embodiment corresponding to fig. 1 of the present application, an operator node selects a target bid evaluation node and a verifier node for a current bid inviting project through a self-evaluator information base, and then sends a bid evaluation signaling to each target bid evaluation node and each verifier node, so that the target bid evaluation node evaluates a plurality of candidate bids in response to the bid evaluation signaling to obtain an evaluation result, and the verifier node verifies the evaluation result obtained by evaluating each target bid evaluation node in response to the bid evaluation signaling to obtain a verification result; after receiving the evaluation result and the verification result, the operator node further determines the final score of each candidate bid, and finally determines the target bid of the current bid item from a plurality of candidate bids based on the final score of each candidate bid, in the process, the authority of the target bid node is verified and/or the service of the target bid node is scored by selecting the target bid node and simultaneously verifying the evaluation result obtained by evaluating the target bid node by the verifier node after evaluating the candidate bid by the bid evaluation node, and the target bid evaluation node is verified by the verifier node while evaluating each candidate bid by the target bid evaluation node, the bid evaluation of the target bid evaluation party is monitored more objectively and fairly while the bid evaluation is performed, and the risk of clustering and enclosing the bid is reduced.
Referring to fig. 3, fig. 3 is a flow chart of another embodiment of the bid evaluation method according to the present application. In the current embodiment, the above step S110 further includes steps S301 to S302.
S301: and selecting the evaluator nodes with the highest integral ranking first preset number in the evaluator information base as target evaluator nodes.
In the current embodiment, in the process of evaluating the bidding document, the service processed by each evaluator node is scored to obtain the integral of each evaluator node. The service processed by each evaluator node includes: a process of evaluating the candidate bid document when selected as the target bid evaluation node and a process of verifying the evaluation result when selected as the verifier node.
When the target bidding party node evaluates each candidate bid document of the current bidding project, specifically, the evaluation is carried out according to the set evaluation rule. Wherein, the evaluation result is a score value. After the target marker evaluation node evaluates the candidate tender document to obtain an evaluation result, the target marker evaluation node creates a block by signing the evaluation result with a private key of the target marker evaluation node, and then broadcasts the created block to the alliance block chain. Before each evaluator node in the evaluation information base is stored in the information base, the identity of each evaluator node is verified by the authority node, and the authority node authorizes the evaluator node to participate in the evaluation. In other embodiments, the identity of each evaluator node may also be verified corresponding to each bidding project, that is, when the evaluator node is selected as the target evaluator node, the authority node verifies and allows the evaluator node to participate in the bid evaluation of the current bidding project. Specifically, the target bidder node signs to create a valid block and adds a certain credit (in some embodiments, the credit may also be understood as a credit score, which may be used to characterize whether the rater node is trusted and whether the business capability is high or low, and when the credit score is higher, it indicates that the rater node is more trusted, and conversely, when the credit score is lower, it indicates that the rater node is less trusted), and when the target rater node creates an invalid or false block, the credit is deducted.
In one embodiment, after a certain evaluator node performs multiple evaluations of candidate bids for bidding items, if the integral of a certain evaluator node is lower than a set threshold, the target evaluator node is not selected as the target evaluator node.
In another embodiment, if the number of target bid evaluation nodes plus the number of verifier nodes equals to the number of evaluator nodes in the evaluation information base, then when all evaluator nodes that are not selected as target bid evaluation nodes in the evaluation information base are used as verifier nodes, after a certain evaluator node performs multiple evaluations on candidate bids of bid inviting projects, if the integral of a certain evaluator node is lower than a set threshold, the target bid evaluation node is not selected as the target bid evaluation node when the target bid evaluation node is selected, and the evaluator node with the integral lower than the set threshold is reduced to the verifier node, and the position of the verifier node with the highest integral is filled.
It can be understood that, in other embodiments, when a part of the evaluator nodes in the evaluation information base that are not selected as the target evaluator nodes are used as the verifier nodes, if the integral of a certain evaluator node is lower than a set threshold, the evaluator node whose integral is lower than the set threshold may be reduced to the verifier node and reduced to a common node, and the position of the verifier node is filled by the verifier node with the highest integral.
Similarly, the verifier node is used for calculating the address of the target bid evaluation node according to the received evaluation result when receiving the evaluation result, and verifying whether the target bid evaluation node is authorized by the authoritative node and has the bid evaluation authority according to the address. The evaluation result is specifically presented as a block, the verifier node may calculate an address of the target evaluator node according to a signature in the evaluation result (which may also be understood as a signature in the block header), verify whether the target evaluator node is an authorization node, and determine whether the target evaluator node has the authority of the signature in the current bid evaluation. If the current target marker node is judged to have the signature authority, the block is judged to be a legal block, and the evaluation result is valid. Similarly, the credit score is added when the verification-preventing node verifies a valid block, and the credit score is deducted if the node of the verifier has an audit error or intentionally cheats, and the credit score is reduced to be a common node when the credit score is lower than the threshold value.
S302: and selecting at least one evaluator node which is not selected as the target evaluator node in the evaluator information base as a verifier node.
In the current embodiment, at least one evaluator node in the evaluator information base that is not selected as the target evaluator node is selected as the verifier node. In the current embodiment, the number of nodes of the verifier is not limited, and is specifically set according to actual requirements.
S303: and respectively sending the bid evaluation signaling to each target bid evaluation node and each verification party node.
S304: and receiving an evaluation result obtained by the target evaluation party node responding to the evaluation signaling to evaluate the candidate bidding documents and a verification result obtained by the verification party node responding to the evaluation signaling to verify the evaluation result.
In the current embodiment, the above steps S303 to S304 are the same as the above steps S120 to S130, and the above description of the corresponding parts may be specifically referred to, and the description is not repeated here.
In the current embodiment, the verification result includes an authority verification result for the target bid evaluation node, and the authority verification result includes: the target bid evaluation node has the verification authority or the target bid evaluation node does not have the verification authority, and the evaluation result is a score value.
Correspondingly, in the current embodiment, the step S140 of determining the final score of each candidate tender further includes steps S305 to S306 according to the evaluation result and the verification result.
S305: if the authority verification result indicates that the target bid evaluation node has the verification authority, determining the evaluation result as an effective evaluation result; or if the authority verification result is that the target evaluation target node does not have the verification authority, determining that the evaluation result is invalid.
When the operator node receives the verification result that: if the target bid evaluation node has the verification right, the operator node determines the evaluation result as an effective evaluation result, otherwise, if the operator node receives the verification result: and if the target marker evaluation node does not have the verification authority, determining that the evaluation result is invalid. If the evaluation result is determined to be invalid, the evaluation result is not selected when the final score of the candidate tender is obtained.
S306: and respectively calculating the mean value of the effective evaluation result of each candidate tender, and taking the mean value corresponding to each candidate tender as the final score of the candidate tender.
After determining the effective evaluation results through step S305, then respectively obtaining the mean values of the effective evaluation results of the candidate bidding documents, and respectively taking the mean values corresponding to the candidate bidding documents as the final scores of the candidate bidding documents.
Further, if the evaluation result includes scores for a plurality of different indexes, step S306 is to respectively obtain a mean value of each index of the candidate bidding documents based on the effective evaluation result, and respectively use the mean value corresponding to each index of each candidate bidding document as a final score of the candidate bidding documents. Wherein the index is also defined as a scoring factor in some of the following embodiments, the index comprising at least: at least one of a bid of the bidder, a project plan of the bidder, a registered capital of the bidder, a development strength of the bidder, a financial status of the bidder, a project reputation score completed by the bidder, a performance of the bidder, a service of the bidder, and a response time of the bidder.
It is understood that in other embodiments, the index may include other content, not listed herein.
S307: based on the final scores of the candidate bids, a target bid for the current bid item is determined from the candidate bids.
