The following is an example of a fictional veterinary blockchain application.

A veterinary blockchain project was established with participation of veterinary hospitals, laboratories, and pet health insurance companies. Dr Smith of ABC Animal Hospital is a participant along with many of her colleagues.

Mrs Jones first presented her spayed female labradoodle Daisy to the clinic and once she shared her public key with the clinic, they were able to access information from all the clinics that Daisy had visited previously. In those records were also entries from diagnostic laboratories, along with time codes and verified user stamps of all participants. In fact, there was even an entry from a genetic testing laboratory indicating that Daisy carried a variant for exercise‐induced collapse, and that might prove very useful should she ever display evidence of weakness.

Over the next few years, Dr Smith came to appreciate the importance of blockchain to medicine. Once, after hours, Daisy needed to be seen at an emergency clinic, and Mrs Jones was able to provide that clinic with a key to access Daisy's healthcare information, including recent bloodwork that had been run. Similarly, when Daisy showed some evidence of lameness, she was referred to a specialist; the specialist appreciated access to the previous medical records, including the genetic screening, and was able to append the medical record with relevant findings, accessible to Dr Smith and others who had been given permission. Laboratory testing that had been performed was similarly entered into the record, directly by the laboratory.

Mrs Jones had purchased pet health insurance for Daisy, which was in effect since Daisy was a puppy. The pet health insurance company participated in the blockchain process and the shared ledger of encrypted data allowed all parties to view the same accurate information about the insurance claim, without anyone having to send medical information back and forth. Mrs Jones found it very convenient to see that the insurance company was able to quickly acknowledge and process the claim.
