# Certified reviews Here is where it gets interesting: the customer now has exclusive access to post a certified review. Logyq’s certified reviews are one-on-one, personal reviews that can only be posted by the account that scanned the QR code, ensuring no fake reviews can be posted. Reviews are also notarized on the blockchain, meaning reliable vendors are likely to get recognized for their qualities, while unreliable and dishonest ones can be easily spotted. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
