Abstract: The present disclosure involves systems and methods for establishing an auditable and tamperproof record of warranty activities among parties to an associated digital warranty file. A blockchain or other distributed ledger may be used to encrypt, seal, and authenticate data associated with a warranty and stored with a warranty management system. Milestones and decisions associated with the digital warranty file may be encrypted and sealed on the blockchain to provide a fully auditable and non-repudiable record of the warranty process, thereby creating a trustworthy validation of warranty file activity as it moves through a warranty claim process. The blockchain based seals allow all participating parties to confidently rely on the information shared. Blockchain based seals of a warranty file or other data may assure the information cannot be tampered with, while reducing costs for researching and verifying each transaction.
