DePIN Node Tutorial

15 minutes to launch a Trinity DePIN node

---

Goal of This Tutorial

Launch a DePIN (Decentralized Physical Infrastructure Network) node.

What you'll learn:

• How to set up a DePIN node
• How to connect to the network
• How to earn rewards
• How to monitor the node

---

What is DePIN?

DePIN is a decentralized network of Trinity inference nodes.

Component	Description
Node	Your server running Trinity
Network	P2P network of nodes
Rewards	$TRI tokens for inference
Mining	Proof of work

---

Step 1: Requirements

Requirement	Minimum
RAM	8 GB
CPU	4 cores
Disk	50 GB SSD
Network	100 Mbps
Zig	0.15.x

---

Step 2: Initialize Node

# Build DePIN components
zig build tri

# Initialize node
./zig-out/bin/tri depin init

# Generate node key
./zig-out/bin/tri depin generate-key

Result:

Node ID: trinity-node-0x1234...
Public Key: 0xabc...
Private Key: stored in ~/.trinity/keys/

---

Step 3: Configure Node

# Edit config
nano ~/.trinity/depin/config.toml

[node]
name = "my-trinity-node"
region = "europe"

[network]
bootstrap_peers = [
    "trinity-bootstrap.example:8765"
]

[mining]
enabled = true
max_concurrent_jobs = 4

[rewards]
address = "0xYourWalletAddress"

---

Step 4: Start Node

# Start node
./zig-out/bin/tri depin start

# Or with logging
./zig-out/bin/tri depin start --verbose

Expected output:

[INFO] Starting Trinity DePIN Node...
[INFO] Node ID: trinity-node-0x1234...
[INFO] Connecting to network...
[INFO] Connected to 5 peers
[INFO] Mining enabled: 4 workers
[INFO] Ready for inference jobs

---

Step 5: Monitor Node

# Check status
./zig-out/bin/tri depin status

# View logs
tail -f ~/.trinity/logs/depin.log

# Check earnings
./zig-out/bin/tri depin rewards

---

Code Example

const std = @import("std");
const depin = @import("depin");

pub fn main() !void {
    var gpa = std.heap.GeneralPurposeAllocator(.{}) {};
    defer _ = gpa.deinit();
    const allocator = &gpa.allocator;

    // Create node
    var node = try depin.Node.init(allocator, .{
        .name = "my-node",
        .max_jobs = 4,
    });
    defer node.deinit();

    // Start
    try node.start();

    // Run forever
    std.time.sleep(std.time.us_per_s * 1_000_000_000);
}

---

Rewards

Action	Reward
Inference job	10 $TRI per 1K tokens
Block validation	1 $TRI per block
Referral	5% of referral earnings

---

Troubleshooting

Problem	Solution
Cannot connect to peers	Check firewall port 8765
Low earnings	Increase max_concurrent_jobs
Out of memory	Reduce max_jobs

---

What's Next?

Tutorial	Description
Deployment	Deploy to Fly.io
BitNet Inference	LLM inference
