## Problems

### Problem 1: Position and Trading Privacy

Large institutional positions and trading activity on public ledgers reveal investment strategies and enable front-running.

**Requirements:**

* **Must hide:** Position sizes, trading activity, order flow, accumulation/distribution patterns
* **Public OK:** Security existence, total outstanding shares, corporate actions
* **Regulator access:** Beneficial ownership reporting (13F, 13D/G), insider trading surveillance, market manipulation monitoring

**Constraints:**

* Securities law disclosure thresholds (5%, 10% beneficial ownership)
* Short-selling disclosure requirements
* Real-time trade reporting obligations

### Problem 2: Competitive Positioning for Exchanges

Traditional exchanges tokenizing equity need privacy to differentiate from transparent crypto venues and protect institutional order flow.

**Requirements:**

* **Must hide:** Exchange-specific order flow data, market maker positions
* **Public OK:** Aggregate volume, price discovery (NBBO)
* **Regulator access:** Full audit trail for market surveillance

**Constraints:**

* Best execution obligations
* Market data revenue models
* Interoperability with traditional settlement (T+1)

## Recommended Approaches

Approach TBD. Consider:

* Integration with existing transfer agent infrastructure
* Privacy-preserving beneficial ownership registries
* Hybrid on-chain/off-chain settlement models

## Open Questions

* How do privacy requirements interact with securities law disclosure obligations?
* What's the path from T+1 settlement to instant atomic settlement?
* How to handle corporate actions (dividends, splits) with position privacy?
