Nebula Sentient Artificial Intelligence (SAI) Policy

Last updated: November 10, 2025

Purpose. This policy defines how Nebula SAI operates across BTCX products. “Sentient” is a brand term for high‑fidelity, multimodal, context‑aware behavior; it is not a claim of consciousness or personhood.

Scope & Architecture

• SI (Synthetic Intelligence). Real‑time trading helpers, arbitrage scanning, and yield optimization under hard risk budgets.
• AI (Artificial Intelligence). Risk management, predictive modeling, and embodied avatars (BTCX VXR).
• Control plane. AI proposes → human and/or policy guardrails approve → SI executes (or simulates).

Safety & Constraints

• No custody by default. No transfers without user‑signed transactions or revocable allowances.
• Risk budgets. Per‑trade and daily loss caps; instrument whitelists; circuit breakers.
• Human‑in‑the‑loop. Autonomy is opt‑in and visibly bounded by user‑defined budgets; global kill‑switch available.
• No guarantees / no advice. Analytics only. Users remain responsible for their decisions.

Data & Privacy

• Data minimization; encryption in transit and at rest; PII kept separate from telemetry.
• Retention windows with aggregation for research; audit logs are tamper‑evident.

Models & Updates

• Staged rollout (sandbox → canary → production) with measurable deltas and drift monitoring.
• Reproducibility: datasets, model hashes, and prompts are versioned; changes are logged.
• Red‑team testing for manipulation, leakage, and injection.

Blockchain Anchors

• Bitcoin: policy hash published as a timestamped “relic”.
• Ethereum: governance registry emits PolicyUpdated(root, uri, version) (EIP‑712 signatures).
• Solana: high‑frequency heartbeats for near‑instant global synchronization.

Incident Response

• Automatic pause on abnormal loss, stale feeds, or signature mismatch.
• On‑chain kill‑switch; public post‑mortem and rollback to last good root.
