Pulsar
Lux is not merely adding post-quantum signatures to a chain; it defines a hybrid finality architecture for DAG-native consensus, with protocol-agnostic threshold lifecycle, post-quantum threshold sealing, and cross-chain propagation of Horizon finality.
See LP-105 §Claims and evidence for the canonical claims/evidence table and the ten architectural commitments — single source of truth.
Pulsar is the Lux-evolved post-quantum threshold signature stack for Quasar consensus, derived from daryakaviani/corona (academic 2-round threshold signature from LWE) with the protocol additions needed to operate on a leaderless open public chain.
Why "Pulsar"
Lux (Latin) → light. Pulsar → SI unit of luminous flux. Each validator emits a "pulsar" of signature toward consensus; aggregated, they form the chain's overall light. Brand-paired with Quasar (the consensus that consumes them).
Relationship to upstream Corona
The upstream repo at daryakaviani/corona is an academic proof-of-concept ("not ready for production use" per its README). Pulsar is the production track:
| Layer | Upstream Corona | Pulsar |
|---|---|---|
| 2-round threshold sign | ✅ same byte-equal protocol | ✅ inherited |
| Trusted-dealer Gen | ✅ for fixed federation | ✅ retained for bridge MPC |
| Proactive resharing for epoch validator rotation | ❌ not specified | 🚧 pulsar/reshare/ (this fork) |
| Pedersen DKG over R_q with proper hiding | ❌ not specified | 🚧 pulsar/dkg2/ (this fork) |
| Per-validator triple-sign integration with Quasar | ❌ N/A | 🚧 pulsar/consensus/ integration |

Status
WIP. The 2-round Sign+Verify path is byte-equal-validated against the academic Corona spec via 16 SHA-256 KATs. The Pulsar-specific additions (resharing + Pedersen DKG) are under design and implementation.
