Simulator, determinism, byte inspector, vectors.
An educational browser-based simulator. It runs the real Domino Compass math in your browser — nothing is sent anywhere.
Paste an 8×7 Domino Compass transcript (two passes of 28 tiles), or load the sample. Rows 1–4 = pass 1, rows 5–8 = pass 2. Each pass uses all 28 tiles exactly once. Doubles carry a compass quadrant (p/b/d/q).
A dedicated reproducibility tool. Enter an example recipe and entropy, and the page outputs the root commitment, transcript hash, identity fingerprint, Bitcoin fingerprint, and capability fingerprint. Reload the page and reproduce the same outputs.
Official Domino Compass test vectors — valid, invalid, boundary, versioning, and domain-separation cases. Downloadable as JSON.
| Category | What it covers |
|---|---|
| Valid cases | Correct transcripts and recipes producing expected outputs |
| Invalid cases | Malformed tokens, wrong token counts, bare doubles without a quadrant |
| Boundary cases | Edge token values, minimum/maximum indices |
| Versioning cases | Different recipe/derivation/encoding versions producing different results |
| Domain-separation cases | Identity vs Bitcoin lanes, different child indices, different scopes |
The derivation transcript at the byte level — protocol documentation, not ordinary web copy. Expand and collapse every derivation stage.
Each field is serialized as 1-byte tag || 2-byte big-endian length || field bytes, in fixed order.
Site search indexes protocol terms and immediately resolves concepts.
