Validator Overview
Run a validator on lumera protocol mainnet and help secure the network.
What is a Lumera Validator?
Lumera is a Cosmos SDK Layer-1 blockchain secured by CometBFT (formerly known as Tendermint) consensus. Validators produce blocks, vote on governance proposals, and maintain the integrity of the network. In return they earn staking rewards and commission from their delegators.
Validators who additionally register as Supernodes can also provide Cascade storage services and earn fees from file storage operations. This guide covers the base validator setup. See the Supernode Overview for upgrading to a Supernode.

Binary Version
Run the version mainnet is currently on.
Releases ship a prebuilt linux/amd64 binary together with the CosmWasm shared library and an installer. ARM (including Apple Silicon) is not supported for production nodes.
Hardware Requirements
These are the specifications published in the lumera-networks repository for mainnet.
| Component | Minimum | Recommended |
|---|---|---|
| CPU | 8 cores (x86_64) | 16 cores |
| RAM | 32 GB | 64 GB |
| Storage | 2 TB NVMe SSD | 4 TB NVMe SSD |
| Network | 1 Gbps dedicated | 5 Gbps+ |
| OS | Ubuntu 22.04 LTS or later | Ubuntu 24.04 LTS or later |
Use NVMe SSDs. Mechanical drives cannot sustain a live CometBFT node, and SATA SSDs stall under load.
What You Need
- A VPS or bare-metal server running Ubuntu 22.04 LTS or later (x86_64)
- At least 1 LUME (1,000,000 ulume) for minimum self-delegation and fees. You will need significant amount of LUME to enter the active set, which is capped at 50 validators.
How This Guide Is Organised
- Node Setup install
lumerad, sync the node, run it under systemd. - Create Validator create a secured wallet, fund it, submit the validator transaction.
- Operations day-to-day commands, chain upgrades, monitoring, troubleshooting.
