Abstract:

A method for immutability of review verifications includes: storing a blockchain; receiving a review submission from a reviewer about an entity comprising feedback; identifying a review identifier unique to the review submission; generating a new review block for the blockchain including the review submission including the review identifier; receiving verification submissions from other reviewers about the review submission indicating positive or negative verification of the review submission; generating verification blocks for the blockchain that include the verification submissions; adding a trustworthiness block to the blockchain for the review once enough positive verifications are received; and adding a trustworthiness block to the blockchain for the reviewer once they have enough trustworthy reviews.
