⏰ Time to Market

Weeks to create a functional IoT circuit

✅ With ZK-IoT SDK

🎯 Ready-Made Templates

Pre-optimized IoT circuits, proven patterns, best practices built-in

🔍 Visual Debugging

Interactive inspector, constraint profiling, automated tests

📖 Documentation++

Interactive examples, step-by-step guides, active community

⚡ Rapid Development

Hours to prototype, minutes to test

Developer Tools Suite

📋Circuit Templates

Pre-built Noir circuits for common IoT sensors (temperature, GPS, motion, etc.)

use zk_iot::sensors::Temperature;

fn main(temp: Field, threshold: Field) -> pub Field {
    Temperature::above_threshold(temp, threshold)
}

🔍Circuit Inspector

Interactive constraint visualizer, performance profiler, automatic optimizer

Features

• R1CS constraint analysis
• Bottleneck detection
• Optimization suggestions

🧪Test Framework

Automated test suite for IoT circuits with simulated data and edge cases

describe('Temperature Circuit', () => {
  test('validates threshold proof', async () => {
    const result = await zkIoT.test.temperature({
      value: 25.5, threshold: 25.0
    });
    expect(result.proof).toBeTruthy();
  });
});

📊Benchmarking Suite

Automatic performance metrics: proof time, size, constraints

Tracked Metrics

• Proof generation time
• Proof size
• Number of constraints
• Memory usage

🔧CLI Tools

Command-line tools for scaffolding, compiling, and deploying

zk-iot create --template sensor-monitoring

zk-iot test --benchmark --coverage

Concrete Usage Example

🔧 Before (Pure Noir)

// Complex circuit to write manually
fn main(
    temperature: Field,
    latitude: Field, 
    longitude: Field,
    threshold: Field,
    zone_bounds: [Field; 4]
) -> pub [Field; 3] {
    // Manual validation logic
    let temp_valid = temperature - threshold;
    let lat_in_bounds = /* complex logic */;
    let lng_in_bounds = /* complex logic */;
    // Manual constraint management
    assert(temp_valid >= 0);
    // ... lots of boilerplate code
    [temp_valid, lat_in_bounds, lng_in_bounds]
}

✅ With ZK-IoT SDK

use zk_iot::prelude::*;

fn main(
    sensor_data: SensorReading,
    constraints: IoTConstraints
) -> pub IoTProof {
    // Optimized and tested circuit
    IoTValidator::new()
        .temperature_above(constraints.temp_threshold)
        .location_within(constraints.authorized_zone)
        .validate(sensor_data)
}

// Automated test and benchmark
const circuit = new ZkIoTCircuit('sensor-validator');
const proof = await circuit.prove({
  temperature: 25.5,
  location: [48.8566, 2.3522]
});
// Automatic metrics
console.log(circuit.getBenchmarks());
