Validator Overview
Run a validator on Lumera Protocol and help secure the network.
What is a Lumera Validator?
Lumera is a Cosmos SDK Layer-1 blockchain secured by CometBFT (Tendermint) consensus. Validators produce blocks, vote on governance proposals, and maintain the integrity of the network.
Validators who additionally register as Supernodes can also provide Cascade storage services and earn additional fees from file storage operations. This guide covers the base validator setup, see the Supernode Overview for upgrading to a Supernode.
