ZIP-0809

Mesh Identity, Gossip & Payments (PQ) — Zoo mirror of HIP-0077

Draft

Zoo-side mirror of Hanzo HIP-0077. Adopts ML-DSA-65 mesh identity, Lux-consensus-backed gossip, and on-chain receipt payments on Zoo Network under the canonical ZOO_STRICT_PQ profile. Heavy spec lives in HIP-0077; this ZIP pins Zoo's ProfileID, gossip namespace, and integration surface.

ZIP-0809: Mesh Identity, Gossip & Payments (PQ)

Abstract

ZIP-0809 mirrors Hanzo HIP-0077 into Zoo Network. Every Zoo-attached device, MCP endpoint, validator, conservation oracle, indexer, and ZRC-721 token-bound account runtime derives its keypair from one HD mnemonic; the signing key is ML-DSA-65 (FIPS 204), reused from the existing luxfi/crypto/mldsa primitive (one implementation in the tree, per ZIP-0014). mDNS TXT carries the 20-byte ML-DSA address; the ZAP handshake carries the full pubkey plus a fresh signature over the server-supplied nonce; cross-LAN propagation rides on the shared consensus mesh under the canonical ZOO_STRICT_PQ profile. Conservation-impact payments and ZRC-20/721/1155 receipt settlement use the same ML-DSA-signed promise/receipt pairs.

This ZIP does not redefine the protocol. The wire format, derivation paths, gossip namespace shape, and receipt schema live in HIP-0077. ZIP-0809 pins Zoo-specific facts.

ProfileID = 0x04 ProfileZooStrictPQ is reserved for Zoo Network in the canonical config.ProfileID registry alongside Lux's 0x01. Profile fields are byte-identical to LuxStrictPQProfile; the ProfileID distinguishes the chain, the field values pin the NIST-PQ track.

Zoo-specific bindings

  • Key derivation. Reuses the Lux SLIP-44 derivation path (m / 44' / 9000' / nid' / 0 / n for ML-DSA identity, .../1/n for the chain account), with nid' = 122' (Zoo Network chain ID per ZIP-0015) for the Zoo primary chain.
  • Gossip namespace. zoo/mesh/v1/<nid>/<org> published over the shared consensus subscription channel; records expire ≤ 5 min; jurisdiction-neutral per Zoo Labs Foundation governance.
  • Token-bound accounts. ZRC-721 wildlife NFTs with ZIP-0703-style token-bound accounts MAY publish a role=tba gossip record; receipts attach to the conservation-impact oracle (ZIP-0501).
  • Auto-funding. ZRC-20 $ZOO pre-allocation to the first 200 LIGHT_MNEMONIC indices is devnet only. The Zoo production network MUST NOT pre-allocate from any public mnemonic.

Compliance

A Zoo node MUST refuse ZAP handshakes whose advertised profile is not ProfileZooStrictPQ or a strict superset, and MUST refuse gossip records whose proof_system_id is a forbidden marker (0x80, 0x81).

Cross-ecosystem bridging (ZIP-0042, ZIP-0800, ZIP-0808) MUST verify the counterpart chain's profile fields are byte-equal to ZOO_STRICT_PQ modulo the ProfileID byte before accepting an inbound transfer. Lux's LUX_STRICT_PQ (0x01) qualifies; any profile that differs in ForbidPairings, ForbidKZG, ForbidTrustedSetup, ForbidClassicalSNARKs, MinSoundnessBits, or MinHashOutputBits does not.

Governance

ZIPs are governed by Zoo Labs Foundation via the canonical process at zips.zoo.ngo. Activation of ZIP-0809 requires sibling activation of ZIP-0810 / 0811 / 0812 (the Z-Chain / Q-Chain / Pulsar-M-DKG mirrors).
