# The Architecture of Trustless Privacy

The Darkswap architecture is built on **four core components**, each contributing to privacy, performance, and institutional-grade reliability.

### **1. Retail User Interface (**Web & Desktop**)**

#### A. Retail Web Interface (dApp) — for all users

A browser-based trading interface with wallet support. \
Users can:

* Place/cancel orders
* View fills
* Track points
* Manage balances

All transactions use Singularity’s privacy layer, so external observers cannot infer trade size, direction, or intent.

#### B. Darkswap Desktop App — for advanced & professional users

A native desktop execution client designed for high-throughput and institutional workflows.

Purpose:\
Provide a stable, high-performance environment with deeper control than the browser UI.

Key capabilities:

* Faster and more persistent connections
* Better performance for active traders
* Advanced order management workflows
* Direct integration with Maker API Server
* Bulk order submission and inventory management
* Equal privacy guarantees to the web app, but with professional tooling

This app is intended for market makers, funds, and professional traders who require a dedicated execution environment.

### **2. On-Chain Settlement Layer**

A **non-custodial privacy-layer settlement system** leveraging smart contracts.

Core responsibilities:

* Verifying **zero-knowledge proofs**
* Executing **atomic swaps**
* Ensuring settlement correctness and finality

The settlement contract:

* Validates that trades follow the rules
* Performs the token transfers
* Keeps everything **deterministic and auditable**
* While **never revealing trade details on-chain**

This preserves **public blockchain guarantees** (finality, auditability) without sacrificing privacy.

### **3. Maker API Server**

Designed for **professional market makers**.

Market makers run a **self-hosted API server** that allows them to:

* Submit bulk orders
* Manage inventory
* Connect to proprietary trading systems
* Maintain low-latency, automated order flow

**The Desktop App** will offer a GUI layer that sits on top of this API for institutions that want advanced tools without building their own client.

### **4. Matching Engine**

#### **Current**

A **centralized coordinator** operated by the team:

* Receives **obfuscated orders**
* Performs matching without seeing cleartext intent

The coordinator **never accesses real order details**, preserving privacy while maintaining high performance.

#### **Roadmap**

A **decentralized peer-to-peer (P2P) matching network**, where:

* No single node has the complete orderbook
* Each peer holds only **partial views**
* Matching occurs collaboratively
* Privacy is preserved via architectural design

This creates a **trust-minimized, censorship-resistant** matching ecosystem.

## **Design Outcome**

Combined, these four components deliver:

* **Confidential trade execution**
* **Verifiable and deterministic on-chain settlement**
* **Institutional trust and auditability**
* **Robust privacy without sacrificing performance**

A structure purpose-built for **secure, private, and scalable darkpool trading** on Darkswap.
