Transplant Allocation Ledger

Match by priority.
Prove it was fair.

Anchor donor registration, recipient waitlist priority, and the matching decision as verified records across every participating hospital. The transplant authority gains an auditable trail proving each allocation followed the established medical priority rules.

The Foundation

The Execution Mechanics

Make organ allocation transparent and auditable across many hospitals at once.

01.

Verified Donor Registry

The Civil Registry module anchors each donor registration as a verified record, so the pool of available organs rests on authenticated identities.

02.

Credentialed Waitlist

The DID and VC Ledger binds each recipient to a credentialed identity and clinical priority, so a waitlist position cannot be quietly altered.

03.

Rule-Bound Matching

The Compliance Attestations module records that each match satisfied the medical priority rules, turning a policy into an enforced, checkable decision.

04.

Immutable Decision Trail

Every allocation, including why a higher-priority recipient was skipped, is sealed on-chain, so the process can be audited long after the fact.

05.

Cross-Hospital View

Donors and recipients across facilities are matched against one shared registry, ending the fragmentation that makes fair allocation hard to verify.

06.

Authority Oversight

The transplant authority queries any allocation and confirms it followed the rules, replacing after-the-fact investigations with a live, verifiable trail.

The Allocation Lifecycle

Follow one donor organ from registration through rule-bound matching to an audited allocation.

Smart Contract Anatomy

Cerulea decomposes transplant allocation into modular contracts. Each layer registers, ranks, matches, and proves without any single hospital controlling the decision.

Applicability Across the Spectrum

Transparent transplant allocation is a horizontal capability. Here is how different actors in the transplant chain put it to work.

Transplant Hospitals

Register donors and recipients into one shared registry and receive rule-bound match decisions, so allocation no longer depends on reconciling separate hospital lists.

Key Asset Types

  1. 1Donor Records
  2. 2Recipient Waitlists
  3. 3Match Decisions

Recipients & Families

Trust that waitlist priority is anchored and cannot be quietly altered, and that any decision affecting a placement is permanently recorded with its clinical basis.

Key Asset Types

  1. 1Waitlist Positions
  2. 2Priority Scores
  3. 3Decision Records

Transplant Authorities

Audit any allocation against the priority rules in one query, replacing after-the-fact investigations with a live, verifiable trail proving the process was followed.

Key Asset Types

  1. 1Audit Trails
  2. 2Compliance Records
  3. 3Allocation Registries

Network & Execution Architecture

Whether you are bridging hospital transplant systems or capturing registrations from an authority portal, Cerulea routes both into one allocation record.

Track A: Hospital System Bridging

For transplant centres on legacy systems. Donor and recipient events are translated into signed on-chain registry entries and matches through the API gateway.

Technical Methodology

The legacy timeline reflects national registry integration benchmarks. Wiring each transplant centre, encoding the medical priority rules, and shipping an oversight audit view for an average network takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your priority and matching rules into pre-audited WebAssembly binaries and provisions the allocation ledger instantly.
