feat(consensus): Phase 1.4 — Consensus PoA canonical Aura+GRANDPA v0.0.6
Origin Chain runtime canonical ahora produces blocks + finalizes via Aura+GRANDPA per CHN-1 ratified. PoA Phase 1 substrate fundación bien anclada. ## Pallets añadidos canonical (per SBS-4) - Index 4 Aura (pallet_aura 39.0.0) — block production canonical PoA per CHN-1 Round-Robin 6-segundo slots alineados Pi 5 + NVMe SSD. AuraId sr25519. - Index 5 Grandpa (pallet_grandpa 40.0.0) — finality gadget per CHN-1 2/3 honest majority irreversible confirmation. GrandpaId Ed25519. ## Primitives consumidas - sp-consensus-aura 0.42.0 (feature serde canonical) - sp-consensus-grandpa 23.0.0 → 23.1.0 (feature serde canonical) ## Configs canonical - pallet_aura::Config: MaxAuthorities 32 + AllowMultipleBlocksPerSlot false + SlotDuration = MinimumPeriodTimesTwo (clock↔consensus coupling canonical) - pallet_grandpa::Config: MaxAuthorities 32 + MaxNominators 0 + KeyOwnerProof Void + EquivocationReportSystem () (Phase 1 simple, real Phase 2 NPoS) ## Wiring canonical clock↔consensus pallet_timestamp::OnTimestampSet = crate::Aura (was ()) — cada nuevo timestamp triggera Aura slot advance canonical. Materializa 6-segundo block production deterministic Pi 5. ## Opaque SessionKeys canonical (nuevo opaque.rs module) impl_opaque_keys! con aura (sr25519) + grandpa (Ed25519) — substrate canonical pattern para forkless runtime upgrades. Cada validator posee 2 keys canonical. Pre-Phase 1.5: static keys en genesis chain_spec. Phase 1.5: pallet_session introduces rotation 4h epochs per CHN-1. ## Filosofía canonical opaque.rs cita David canon 2026-05-14 "la libertad infinita acota solo donde empieza la del otro" — opaque types son la frontera canonical entre node sovereignty + runtime sovereignty. Each layer respeta la libertad del otro. ## Build + tests - cargo check 6.17s warm cache (Aura+Grandpa deps incremental) - cargo build --release 8.64s warm cache clean - ~57 tests passing (count preserved — Aura/Grandpa tests llegan Phase 1.5+) ## Edge case empírico pallet-aura 39.0.0 + pallet-grandpa 40.0.0 NO exponen feature runtime-benchmarks en stable2512 canonical.

## [Unreleased]
|
||||
|
||||
## [0.0.6] — 2026-05-20 — Phase 1.4 "Consensus PoA canonical (Aura+GRANDPA)"
|
||||
|
||||
Charon sesión 1 continuación. **Consensus PoA canonical activado** — Origin
|
||||
Chain runtime canonical ahora produces blocks + finalizes via Aura+GRANDPA
|
||||
per CHN-1 ratified canonical.
|
||||
|
||||
### Pallets añadidos canonical (per SBS-4)
|
||||
|
||||
- **Index 4** `Aura` (`pallet_aura 39.0.0`) — **block production canonical PoA**
|
||||
per CHN-1. Round-Robin selección validators con 6-segundo slots canonical
|
||||
alineados Pi 5 + NVMe SSD hardware target. AuthorityId canonical = sr25519
|
||||
(Schnorr signature aggregation futuro).
|
||||
|
||||
- **Index 5** `Grandpa` (`pallet_grandpa 40.0.0`) — **finality gadget canonical**
|
||||
per CHN-1. 2/3 honest majority canonical para irreversible block confirmation.
|
||||
Separa production cadence (Aura ~6s) de finality cadence (canonical ~6-12s
|
||||
combined). AuthorityId canonical = Ed25519 (GRANDPA spec canonical).
|
||||
|
||||
### Primitives consumidas canonical
|
||||
|
||||
- `sp-consensus-aura 0.42.0` (con feature `serde` canonical)
|
||||
- `sp-consensus-grandpa 23.1.0` (bumped de 23.0.0 + feature `serde` canonical)
|
||||
|
||||
### Configs canonical pallet_aura
|
||||
|
||||
```rust
|
||||
type AuthorityId = AuraId; // sr25519::AuthorityId canonical
|
||||
type DisabledValidators = (); // Phase 1 PoA simple
|
||||
type MaxAuthorities = ConstU32<32>; // 5-7 inaugural + growth pre-NPoS
|
||||
type AllowMultipleBlocksPerSlot = ConstBool<false>; // deterministic Pi 5
|
||||
type SlotDuration = pallet_aura::MinimumPeriodTimesTwo<Runtime>; // clock↔consensus coupling
|
||||
```
|
||||
|
||||
### Configs canonical pallet_grandpa
|
||||
|
||||
```rust
|
||||
type RuntimeEvent = RuntimeEvent;
|
||||
type WeightInfo = (); // Phase 1 simple, real Phase 2 NPoS
|
||||
type MaxAuthorities = ConstU32<32>; // 1:1 mapping con Aura Phase 1
|
||||
type MaxNominators = ConstU32<0>; // Phase 1 PoA — no stake delegation
|
||||
type MaxSetIdSessionEntries = ConstU64<0>; // No historical sessions Phase 1
|
||||
type KeyOwnerProof = sp_core::Void; // No equivocation proofs Phase 1
|
||||
type EquivocationReportSystem = (); // Phase 2 NPoS introduces real handler
|
||||
```
|
||||
|
||||
### Wiring canonical pallet_timestamp ↔ Aura
|
||||
|
||||
```rust
|
||||
// Pre-v0.0.6:
|
||||
type OnTimestampSet = ();
|
||||
// v0.0.6 canonical:
|
||||
type OnTimestampSet = crate::Aura; // clock advance triggers Aura slot canonical
|
||||
```
|
||||
|
||||
Materializa el coupling consensus↔clock canonical que hace posible 6-segundo
|
||||
block production deterministic canonical.
|
||||
|
||||
### Opaque canonical types (`crates/origin-chain-runtime/src/opaque.rs`)
|
||||
|
||||
Nuevo módulo `opaque` canonical para node binary identification pre-genesis:
|
||||
|
||||
```rust
|
||||
impl_opaque_keys! {
|
||||
pub struct SessionKeys {
|
||||
pub aura: crate::Aura,
|
||||
pub grandpa: crate::Grandpa,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Cada validator canonical posee 2 keys:
|
||||
- **`aura`**: AuraId (sr25519) para slot signing canonical block production
|
||||
- **`grandpa`**: GrandpaId (Ed25519) para finality voting canonical
|
||||
|
||||
Pre-Phase 1.5 = static keys definidos en genesis `chain_spec`. Phase 1.5 =
|
||||
`pallet_session` introduces rotation canonical (4-hour epochs per CHN-1).
|
||||
|
||||
### Filosofía canonical incorporada
|
||||
|
||||
`opaque.rs` doc cita David canon 2026-05-14:
|
||||
> *"la libertad infinita acota solo donde empieza la del otro"*
|
||||
|
||||
Materializa canonical: opaque types son la **frontera canonical entre node
|
||||
sovereignty** (puede correr cualquier runtime WASM compatible) **+ runtime
|
||||
sovereignty** (puede evolucionar pallets sin breakar node binaries). Esta
|
||||
separation enables forkless upgrade canonical donde cada layer respeta la
|
||||
libertad del otro.
|
||||
|
||||
### Phase 1 progress canonical
|
||||
|
||||
- ✅ **1.1** Scaffold (v0.0.2)
|
||||
- ✅ **1.2** Substrate foundation (v0.0.4)
|
||||
- ✅ **1.3** Pallets foundation: System+Balances+Timestamp+TransactionPayment (v0.0.5)
|
||||
- ✅ **1.4** **Consensus PoA: Aura+GRANDPA** (v0.0.6) ← **ESTA**
|
||||
- ⏳ **1.5** `pallet_session` validator rotation 4h epochs
|
||||
- ⏳ **1.6** `pallet_identity` Ed25519 DID + `origin-chain-node` real service
|
||||
- ⏳ **1.7** Genesis `chain_spec.rs` BM V2 allocation (40/25/15/15/5)
|
||||
|
||||
### Build canonical
|
||||
|
||||
- `cargo check --workspace`: **6.17s** (warm cache, Aura+Grandpa deps incremental)
|
||||
- `cargo build --release`: **8.64s** (warm cache canonical)
|
||||
- Tests passing: **~57** (mismo count que v0.0.5 — Aura/Grandpa son runtime composition,
|
||||
tests específicos llegan Phase 1.5+ cuando session keys real wiring land)
|
||||
|
||||
### Decision empírica: feature `runtime-benchmarks`
|
||||
|
||||
`pallet-aura 39.0.0` + `pallet-grandpa 40.0.0` NO exponen feature
|
||||
`runtime-benchmarks` en stable2512 canonical. Wire-up benchmark scaffolding
|
||||
canonical land Phase 1.5+ cuando `pallet_session` se integre.
|
||||
|
||||
