| # Retro-Sync: Hurrian Hymn h.6 — 71-Shard NFT Collection |
|
|
| The world's oldest surviving notated music (~1400 BC, Ugarit) encoded as a |
| multi-layered NFT collection with ZK proofs and steganographic embedding. |
|
|
| ## Collection |
|
|
| **71 DA51 CBOR shards** — one for each integer 1..71 (the crown prime). |
| 20 generator shards (primes ≤ 71) carry the SSP interval structure. |
| 51 derived shards (composites) carry content determined by prime factorization. |
|
|
| | Layer | Content | Format | |
| |-------|---------|--------| |
| | Source | Babylonian notation, interval mapping | text | |
| | Notation | LilyPond score (West 1994) | .ly | |
| | Artifacts | MIDI, PDF score, WAV audio | base64 in CBOR | |
| | Witnesses | Compilation chain (5 steps) | JSON | |
| | Eigenspace | Earth/Spoke/Hub decomposition | numeric | |
| | Metadata | Tablet, scribe, tuning, deity | structured | |
| | References | Wikipedia, scholarly, LilyPond docs | URLs | |
| | YouTube | Private audio comparison sources | URLs | |
| | Pipeline | SOP, erdfa CFT, boustrophedon, Cl(15) | text | |
| | ZK Proof | Groth16/BN254, MiMC Merkle tree | JSON | |
|

|
|
| ## Decoding |
|
|
| Each shard is a DA51-tagged CBOR envelope: |
| - Bytes 0-1: `0xDA 0x51` (magic) |
| - Bytes 2-9: SHA-256 prefix (CID stub) |
| - Bytes 10+: CBOR payload |
|
|
| ```python |
| import cbor2, json |
| with open("nft71/02.cbor", "rb") as f: |
| raw = f.read() |
| magic = raw[:2] # b'\xda\x51' |
| cid = raw[2:10].hex() |
| payload = cbor2.loads(raw[10:]) |
| print(json.dumps(payload, indent=2)) |
| ``` |
|
|
| ## ZK Verification |
|
|
| The Groth16 proof verifies: |
| 1. Prover knows all 71 shard hashes |
| 2. All form a valid MiMC Merkle tree |
| 3. Eigenspace commitment matches (100% Earth) |
| 4. Crown shard (p71) is unique |
