## Research Areas

Current research includes:

* **Zero-knowledge proof systems** for privacy-preserving settlements
* **Multi-chain interoperability** for cross-platform transactions
* **Cryptographic verification** of energy generation and consumption
* **Decentralized identity** for energy prosumers and assets

## Integration Points

Layer 5 will provide settlement for:

* **Layer 4**: Coordinated energy transactions and services
* **Layer 6**: User-facing payment and billing interfaces
* **External systems**: Traditional utility billing and regulatory compliance

***

*The settlement layer ensures trust and transparency in the new energy economy. Follow our research progress on [GitHub](https://github.com/qubit-foundation).*
