Systems and methods are disclosed for providing a virtual updated appraisal of a valuable asset without an onsite inspection. The appraisal system may provide attestation of the integrity of the updated appraisal generated by verifying the asset through video and image capture transmissions and geolocation data extracted from the transmissions. The updated appraisal may be configured as self-authenticating and recorded in a transaction on a blockchain, accessible via a QR code image. The updated appraisal may be stored in a blockchain wallet and configured as a non-fungible token. The geolocation data can enables the appraisal system to verify the integrity of the submission and thereby reduces the chance of fraud. In this way, updated appraisals generated by the system can increase confidence for insurance companies as to the authenticity and accuracy of the updated appraisal.
