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.
Node | Components |
Full node | kroma-geth, kroma-node |
Sequencer | kroma-geth, kroma-node, kroma-batcher |
Validator | kroma-geth, kroma-node, kroma-validator, kroma-prover |
The following are the minimum and recommended hardware requirements to run each client on Kroma:
| Minimum | Recommended |
kroma-geth |
|
|
kroma-node |
|
|
kroma-validator |
|
|
kroma-prover |
|
|
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.
