Answer

As a distributed database for storing reviews, verification information and credibility scores, the blockchain is tamper-proof and ensures the authenticity and reliability of the information.

The reviewer identifier represents the unique identifier of the user who submitted the review, and the entity identifier represents the unique identifier of the service entity or product being reviewed.

The review identifier is a unique identifier assigned to each review, which is used to associate the review with the corresponding verification information.

The verification submission contains the reviewer identifier of the verifier, the review identifier of the verified review, and the verifier's affirmative or negative judgment on the review.

The review block stores the reviews submitted by the user, and the verification block stores the verification information of the verifier on the review.

By counting the number of positive and negative verifications for a review, when the number of positive verifications reaches a preset threshold, the review is considered credible.

The credibility block contains the review identifier of the verified review and the credibility status of the review (credible or uncredible).

When the number of credible reviews submitted by a reviewer reaches a preset threshold, the reviewer is considered a credible reviewer.

Consumers can view all reviews and verification information of the service entity by accessing the blockchain, or view the score calculated by the system based on the credibility.

The system uses the immutability of the blockchain to ensure the authenticity and reliability of the reviews and verification information, solves the problem that information in traditional review systems is easily tampered with and deleted, and improves consumers' trust in reviews.
