Structural Graph Identity and Post-Quantum Security
for Permissionless DAG Finality.
URUZ is a permissionless DAG-based Layer 1 protocol combining work-weighted finality, staged reputation-based Sybil resistance via Structural Graph Identity (SGI), checkpoint-anchored history integrity, and post-quantum trust anchors. The central design choice treats SGI as a phased control system — not an all-at-once consensus switch — allowing the network to advance by verified gates rather than narrative milestones.
Core Design
Each layer evolves on its own timeline — execution, finality, checkpointing and identity controls are independently upgradeable.
Parallel transaction propagation and conflict handling in a directed acyclic graph, enabling high-throughput permissionless processing without sequential bottlenecks.
Policy-bounded deterministic finality. Transactions move through states — PENDING, CONFIRMED, FINAL — only when objective on-chain conditions are satisfied.
Canonical history anchoring and controlled recovery. Reputation influence is constrained by anchored history, protecting against long-range manipulation attacks.
Behavior-derived reputation with staged consensus influence. SGI derives identity signals from durable, verifiable behavior in the DAG — no central authority required.
Architecture
Separation is intentional: execution, finality, checkpointing, and identity controls evolve on different timelines.
SGI
Sybil resistance derived from durable, verifiable behavior in the DAG — no capital requirement, no central registry.
Activation Model
URUZ treats early network life as a distinct security regime. SGI activation depends on measurable network health, not calendar deadlines.
SGI signals are collected and scored passively. Influence is bounded. Network health baselines are established over multiple epochs with continuous telemetry.
SGI begins contributing to consensus weighting within defined ceilings. Concentration and quality signals are tracked. Maturity gates require multi-epoch evidence.
Full SGI consensus weighting enabled after measurable stability and governance gates are met. URUZ does not claim this phase complete before gates are satisfied.

Post-Quantum
No permanent lock-in to a single primitive. PQ domains are separated to reduce migration risk and avoid partial-PQ blind spots.
Post-quantum signature schemes for transaction-level authentication, aligned with NIST FIPS 204 (ML-DSA).
Checkpoint authority paths secured under PQ assumptions, keeping finality integrity robust against quantum-capable adversaries.
Session and node identity paths migrating to PQ-safe primitives, with rotation and revocation hardening on the active roadmap.
