Prerequisites

After completing the How to Set Up a Cardano Stake Pool guide, you will know how to register and operate a secure stake pool on Mainnet. The guide also includes instructions throughout explaining how to configure a stake pool to operate in a Testnet environment.

Operating a stake pool in a Cardano Testnet Environment prior to registering a stake pool in the Mainnet production environment offers a risk-free approach to start learning practically about the technical skills, commitment, responsibilities and benefits of operating a Cardano stake pool.

If you are unsure of the Testnet environment to use to practice registering and operating a stake pool, consider using the Preview testing network environment.

When operating a stake pool on Mainnet, using a Testnet environment to test configuration changes and upgrades as well as troubleshoot any issues that may arise without impacting the production environment is very helpful.

πŸ§™β€β™‚οΈ Mandatory Skills for Stake Pool Operators

As a Stake Pool Operator (SPO) for Cardano, you need:

πŸ§™ Mandatory Experience for Stake Pool Operators

πŸŽ—οΈ Minimum Mainnet Stake Pool Hardware and Operating Requirements

  • Two separate servers: 1 block producer node, 1 registered relay node

  • One air-gapped offline computer (cold environment)

  • Operating system: 64-bit Linux (i.e. Ubuntu 22.04 LTS)

  • Processor: An Intel or AMD x86 processor with two or more cores, at 2GHz or faster

  • Memory: 24GB RAM (including swap space)

  • Storage: 300GB free storage

  • Internet: Static IP address and a broadband connection supporting speeds at least 10 Mbps

  • Data Plan: At least 1GB per day (30GB per month)

  • Power: Reliable electrical power

  • ADA balance: At least 505 ADA for pool deposit and transaction fees

πŸ‹οΈβ€β™‚οΈ Recommended Future-proof Mainnet Stake Pool Hardware and Operating Requirements

  • Four separate servers: 1 block producer node, 3 relay nodes (2 registered relays and 1 unregistered relay) located in at least two different physical locations around the world

  • One air-gapped offline machine (cold environment)

  • Operating system: 64-bit Linux (i.e. Ubuntu 22.04 LTS)

  • Processor: An Intel or AMD x86 processor with four or more cores, at 2GHz or faster

  • Memory: 24GB+ RAM

  • Storage: 350GB+ free storage

  • Internet: Static IP addresses and broadband connections supporting speeds of at least 100 Mbps

  • Data Plan: Unlimited

  • Power: Reliable electrical power with an Uninterruptible Power Supply (UPS) or other backup power source

  • ADA balance: More pledge and stake is better, to be determined by a0, the pledge influence factor

πŸ”¨ Example Testnet Stake Pool Hardware and Operating Requirements

  • One server: 1 block producer node

  • Operating system: 64-bit Linux (i.e. Ubuntu 22.04 LTS)

  • Processor: An Intel or AMD x86 processor with two or more cores, at 2GHz or faster

  • Memory: 8GB RAM

  • Storage: 50GB free storage

  • Internet: Static IP address and a broadband connection supporting speeds at least 10 Mbps

  • Data Plan: At least 1GB per day (30GB per month)

  • Power: Reliable electrical power

  • ADA balance: 0 ADA (Request tokens and stake pool delegations using the Testnets Faucet)

If you need ideas on how to harden your stake pool's nodes, see the topic Hardening an Ubuntu Server.

πŸ› οΈ Setup Ubuntu

Refer to the respective guide to Install Ubuntu Server or Install Ubuntu Desktop.

🧱 Rebuilding Nodes

If you are rebuilding or reusing an existing Cardano Node installation, see the topic Resetting an Installation.
