Why This Exists
Pet health records are fragmented across systems. Paper records can be lost. Conventional digital records can be altered without leaving evidence. There is no standard way to check a pet's documented health history across providers, owners, or care contexts.
Veterinary observations stay inside individual clinic records. Breeding program documentation is scattered across PDFs, screenshots, and email threads. When a pet changes hands, months or years of care documentation often does not travel with it.
These are infrastructure constraints, not failures of the people involved. The documentation tools available to the pet ecosystem were not designed for continuity, portability, or independent checking.
The system is designed to address these constraints through structured record infrastructure.
System Overview
Nebula Genesis Pet Ledger is a record system for documenting and presenting pet-related data across veterinary care, breeding programs, and ownership. The system consists of five core components:
- Veterinary Attestations — Licensed veterinarians create structured documentation records attributed to their hashed credentials.
- DNA Health Assertions — Categorical genetic health data recorded without exposing raw DNA information.
- Record Transfers — Ownership changes recorded through dual-confirmation workflows. Full documented history is preserved.
- Manifest System — Versioned, hash-linked snapshots of record state stored on durable decentralized storage.
- Independent Record Checking — Public tools that allow records to be checked for integrity without requiring an account.
Records are stored across three layers — user devices, Nebula's servers, and public infrastructure (Solana and Irys/Arweave). Privacy is enforced through multiple independent mechanisms including a deny-by-default write guard, on-device credential hashing, and role-gated access controls.

Participants
The system supports four participant roles:
| Participant | Capabilities | Learn More |
|---|---|---|
| Veterinarians | Create attestations, document professional observations, build attributed documentation records | For Veterinarians |
| Breeders | Structured presentation of program records, kennel attribution, record continuity through transfers | For Breeders |
| Pet Owners | Documented health history, record transfers, ownership documentation, lost pet support | Full Whitepaper |
| Pet Seekers | Free record checking, review documented records before making decisions | Full Whitepaper |
Scope Boundaries
- The system does not provide medical diagnoses, treatment recommendations, or genetic counseling.
- The system does not evaluate or rank participants.
- The system does not eliminate all re-identification risk.
- The system does not replace existing microchip registries, veterinary records, or breed registration databases.
- The system does not store owner names, addresses, or contact information on public infrastructure.
- On-chain data cannot be retroactively erased; this limitation is disclosed before record creation.
