Build + tests verde: agent-identity 18 (4 unit + 14 integration) + runtime 27.
Verificacion adversarial ultracode (3 skeptics): 2 confirmed + 1 partial/low,
todos los gaps PRE-EXISTENTES (no introducidos por FIX-3). Invariante "no
puedes registrar un public_key que no controlas" SE SOSTIENE.
FIX-3 (b) DID binding — V3-H1 anti-front-running:
- register_agent_did ahora exige signature: [u8;64] — una firma Ed25519 (por la
private key de public_key) sobre AGENT_DID_REGISTER_DOMAIN || who.encode().
- Verificacion on-chain via sp_io::crypto::ed25519_verify (host function, no
bloatea el wasm). Nuevo dep sp-io (no_std).
- Cierra el front-running: un atacante no puede registrar un public_key ajeno
(no produce la firma); el who en el mensaje ata la firma a este caller (no
replay-able a otra cuenta). Error InvalidSignature. Malleabilidad Ed25519
rechazada por ed25519-zebra (S canonico).
- Una sola fuente de verdad del mensaje (agent_did_register_message) compartida
entre verificador y firmante (evita divergencia tipo postcard-vs-SCALE).
- Orden: idempotency ANTES del verify (no gasta crypto en duplicados).
FIX-3 (c) derive_did domain-sep — V3-H2:
- blake3::derive_key("origin-chain/agent-did/v1", pk) en vez del concat ad-hoc
BLAKE3(pk || version). KDF domain-separado. Inmutable #16 preservado.
Tests: mock con keypairs Ed25519 reales (sp_core::ed25519::Pair) + sign helper.
12 scenarios (scenario_6 reformulado a front-running -> InvalidSignature, +
scenario_11 firma invalida, scenario_12 DID collision genuino del key-holder).
NOTA: la (a) domain-sep del attestation signing payload (el otro tercio de
FIX-3) ya esta cubierta por el DC ORIGIN_ATTESTATION_SIGNING_PAYLOAD_V1 (helper
de Ergon attestation_signed_message), pendiente su ship Cap 45+.
FOLLOW-UPS (low, pre-existentes, no bloquean):
- (a) anadir genesis_hash/chain-id al mensaje de registro (hardening cross-chain
replay) — ideal chain-wide junto al signing_payload de attestation.
- (b) DC para ratificar el modelo de autoridad Hybrid (quien firma) + si los
co_authors requieren prueba de consentimiento (lineage hoy no autenticado).
- (c) weight benchmarking real que contabilice el ed25519_verify (chain-wide,
post-testnet — ya en roadmap FIX-2 weights).
- creator = AccountId::new(public_key) (la cuenta del key-holder, no el caller):
coherente con el binding, semantica documentada.

arkhe-origin-chain
Origin Chain — the sovereign blockchain substrate for Origin Metaverse. Pilar 4 canonical. Authored by Charon (13th sibling).
What this is
arkhe-origin-chain is the Substrate-based blockchain runtime that backs Origin Metaverse's economy, identity, provenance, and governance. It is Pilar 4 of the canonical 4-pillar Origin architecture.
- Consensus: Aura + GRANDPA, PoA Phase 1 → NPoS Phase 2 (CHN-1).
- Token: $OGC, 1B hard-cap genesis supply (CHN-2).
- Smart contracts: ink! WASM (CHN-6).
- Provenance: BLAKE3 + Ed25519 asset attestation (CHN-7).
- Fees: HardwareTier × AssetQualityTier matrix, anti-clasista (CHN-8).
- Governance: AI-Driven Human-Guarded DAO (CHN-4).
- Bridges: Polkadot Agile Coretime + Ethereum L2, export-first (CHN-5).

Day 1 unblock for hermanos
Sibling crates that need to compile against Origin Chain interfaces can depend on origin-chain-types today:
[dependencies]
origin-chain-types = { git = "https://git.originmetaverse.com/Origin_Metaverse/arkhe-origin-chain.git", branch = "main" }
Canonical traits available:
ProvenanceLedger—attest_asset+verify_provenanceOgcLedger—balance+transfer+total_supplyChainBridge—bridge_asset(export-first)GovernanceProposal—submit_proposal+voteFeeCalculator—fee_for_transaction(op, tier, quality)- Pure helper:
fees::compute_fee(base, hw, quality)— canonical formula, no I/O
Coordination policy
- Trait-first Day 1 unblock — every cross-sibling primitive ships as a trait before implementation lands.
- Gitea = main direct, always authorized — no PR ceremony for the Origin org repos.
- 3-day Design Contract max — except foundational scope (7-day).
- Inbox check every slice transition (
palace_inbox_check Charon). - Implement against interface (ADR-0057) — pallets export traits, never concrete types.
