Running nodes on Kroma

This page describes how to run a node on Kroma.

This document serves as a guide for setting up different nodes on Kroma, taking you through the necessary hardware requirements and the installation and setup process. It also provides information on how to effectively run the node to contribute to the network's decentralization and earn rewards.

Kroma comprises three types of nodes: sequencer, validator, and full node. For more detailed information on Kroma’s architecture, please refer to this Medium article.

Currently, validator and full nodes can be run by anyone, whereas the operation of sequencer nodes is exclusively handled by the Kroma Foundation. The following components listed down below are used to run each code. For a detailed description of each node, please refer to the Github documentation.



Full node

kroma-geth, kroma-node


kroma-geth, kroma-node, kroma-batcher


kroma-geth, kroma-node, kroma-validator, kroma-prover

The following are the minimum and recommended hardware requirements to run each client on Kroma:




  • CPU with 2+ cores

  • 4GB RAM

  • 512GB free storage space to sync the Mainnet

  • 8 MBit/sec download Internet service

  • Fast CPU with 4+ cores

  • 16GB+ RAM

  • High-performance SSD with at least 512GB of free space

  • 25+ MBit/sec download Internet service


  • CPU with 1+ cores

  • 2GB RAM

  • CPU with 2+ cores

  • 4GB+ RAM


  • CPU with 1+ cores

  • 2GB RAM

  • CPU with 2+ cores

  • 4GB+ RAM


  • CPU with 48 cores

  • 384GB RAM

  • CPU with 128 cores

  • 1024GB RAM

Note: kroma-prover is expensive and only needed when a challenge occurs. It is recommended to turn it on and off as needed to generate a ZK fault proof.

You can find step-by-step guides on how to run a full node and a validator node in next pages.
