GenLayer Validator Best Practices Guide

Introduction

This guide covers best practices for setting up, running, and maintaining a validator node on the GenLayer Asimov & Bradbury Testnets. Following these practices will improve your uptime, security, and overall validator performance.

---

1. Prerequisites

Before setting up your node, ensure you have:

• Docker 26+
• Node.js 18+
• npm installed
• At least 4GB RAM and 50GB SSD storage

---

2. Installation

Install the GenLayer CLI globally:

npm install -g genlayer

Initialize your environment with 5 validators:

genlayer init --numValidators 5

Use --reset-db for a clean slate during testing.

---

3. Linux Prerequisites (Often Missed!)

The CLI uses keytar for secure key storage, which requires libsecret:

# Ubuntu/Debian
sudo apt-get install libsecret-1-0

# Fedora
sudo dnf install libsecret

---

4. Pin Your Localnet Version

Always pin your version on testnets to avoid breaking changes:

genlayer init --localnet-version v0.10.2

---

5. Connect to the Right Testnet

Using the GenLayer JS SDK, point to the correct chain:

import { testnetAsimov } from 'genlayer-js/chains';
const client = createClient({ chain: testnetAsimov, account });

---

6. Check Validator Status

const isValidator = await client.isValidator("0xYourAddress");
const validators = await client.getActiveValidators();

---

7. Security Best Practices

• Disable password login; use SSH keys only
• Configure UFW firewall with strict port rules
• Store validator key backups encrypted and offsite
• Apply security patches promptly

---

8. Monitoring

• Set up Grafana + Prometheus dashboards
• Connect alerts to PagerDuty or Telegram
• Don't rely on manual checks — automate everything

---

9. Governance Participation

• Monitor GenLayer Discord and governance forums regularly
• Vote on every proposal — abstaining signals inactivity
• Engage in pre-vote discussions to represent your validator's position

---

Conclusion

Following these best practices will ensure your GenLayer validator node is secure, reliable, and positively contributing to the network.
