# synza architecture

## System Overview

SYNZA is built on a **multi-layer architecture** that combines zero-knowledge cryptography, homomorphic encryption, and decentralized compute to enable private AI trading.

## Layer 2: SDK Layer

### SYNZA SDK

The SDK provides easy integration for developers:

```typescript
import { SynzaClient } from '@synza/sdk';

const client = new SynzaClient({
  apiKey: process.env.SYNZA_API_KEY,
  network: 'mainnet',
  privateKey: process.env.WALLET_KEY
});
```

### Core SDK Features

{% stepper %}
{% step %}

### Signal Generation

```typescript
const signals = await client.getSignals({
  token: 'SOL',
  timeframe: '1h',
  minConfidence: 0.85
});
```

{% endstep %}

{% step %}

### Private Trade Execution

```typescript
const trade = await client.executeTrade({
  signal: signals[0],
  amountUSD: 1000,
  slippage: 0.5,
  mevProtection: true
});
```

{% endstep %}

{% step %}

### Vault Management

```typescript
const vault = await client.createVault({
  name: 'My Trading Data',
  encryption: 'AES-256'
});

await vault.uploadData(tradingDataCSV);
```

{% endstep %}

{% step %}

### Real-Time Subscriptions

```typescript
client.subscribeToSignals((signal) => {
  console.log('New signal:', signal);
});
```

{% endstep %}
{% endstepper %}

***

## Layer 3: Protocol Layer

### ZK Proof System

#### Proof Generation Flow

{% stepper %}
{% step %}

### User Action → Create Witness

User triggers an action; witness data is constructed representing inputs to the circuit.
{% endstep %}

{% step %}

### Generate ZK Proof

Prover generates a zero-knowledge proof for the witness and the circuit.
{% endstep %}

{% step %}

### Verify

Verifier (on-chain or off-chain) validates the proof against the circuit.
{% endstep %}

{% step %}

### Execute

Upon successful verification, the intended action (e.g., signal publication, trade commitment) is executed.
{% endstep %}
{% endstepper %}

**Components**:

* **Prover**: Generates zero-knowledge proofs on user device or compute nodes
* **Verifier**: Smart contract on Solana validates proofs
* **Circuit**: Defines valid computation constraints

#### Proof Types

1. **Proof of Signal Generation**: Verifies AI model ran correctly
2. **Proof of Data Ownership**: Proves you own data without revealing it
3. **Proof of Computation**: Validates encrypted computation results
4. **Proof of Trade Intent**: Creates private trade commitment

### MEV Protection Engine

#### Private Transaction Routing

```
Traditional:
User → Mempool (Public) → Validator → Block
          ↑
      MEV Bots See This

SYNZA:
User → ZK Encrypted Intent → SYNZA Router → Private Channel → Block
                                                    ↑
                                         No Mempool Exposure
```

**How It Works**:

1. **Intent Encryption**: Trade encrypted client-side with ZK proof
2. **Routing Decision**: SYNZA network routes to optimal path
3. **Atomic Execution**: Trade executes directly on-chain
4. **Settlement Proof**: ZK proof confirms correct execution

### Signal Verification System

Every signal comes with a **cryptographic proof**:

```json
{
  "signal": {
    "token": "SOL",
    "action": "BUY",
    "confidence": 0.89,
    "targetPrice": 145.32
  },
  "proof": {
    "zkProof": "0x...",
    "modelHash": "0x...",
    "dataHash": "0x...",
    "timestamp": 1702123456
  }
}
```

**Verification**:

* Proof validates signal came from correct AI model
* Model hash ensures no tampering
* Data hash proves input data integrity
* Anyone can verify the proof on-chain
