AtomOne node is the atomoned daemon, a free, open source full node program for the AtomOne network. It is aimed at developers, validators and infrastructure teams who want to run their own copy of a Cosmos-based chain instead of relying entirely on someone else's endpoint. The program is written in Go and is available as a Windows build or installer.
AtomOne is a fork of the Cosmos Hub at version v15.2.0. It reverts to the standard Cosmos SDK v0.47.10 and removes several modules, so the chain behaves differently from Cosmos Hub in specific areas. The current build is labeled v4.2.0-rc.2, a release candidate, and its most recent code update is dated October 29, 2026. The sections below cover what the software does, how to install it, and what to check before you run it.
What Is an AtomOne Node?
An AtomOne node is a program that connects to the AtomOne network, stores a copy of the chain's state and checks every block against the network's rules. The daemon is called atomoned. When it runs, your machine takes part in verifying the network instead of simply reading information from a remote server.
Because AtomOne is built on the Cosmos SDK, the node follows patterns familiar to anyone who has worked with Cosmos-based chains. The project started from the Cosmos Hub codebase and then changed several parts of it. That history matters, because it explains why some behaviors match the Cosmos Hub while others do not.
The node is a client, not a wallet. It handles network communication and block validation, while account keys are managed separately. Keeping that distinction in mind will help you decide what the software can and cannot do on your behalf.
Who Is an AtomOne Node For?
AtomOne node suits several kinds of users. Developers who build applications on the network often run a local node so they can test against the real chain without depending on a public endpoint. Infrastructure teams may run nodes to serve their own internal tools, dashboards or indexing services.
Validators are another audience. Running a validator requires a stable node, careful key management and an understanding of the governance rules that apply on this chain. Because the governance voting rules differ from Cosmos Hub, validator operators should review those differences before they commit to running one.
Curious users who want to learn how a Cosmos-style chain works internally can also use the node as a study tool. Reading the source code, checking sync status and inspecting local data are good ways to understand block production and consensus in practice.
How Forks Change a Blockchain
A fork is a copy of existing blockchain software that is modified to create a separate network or a variant of the original design. AtomOne is a fork of the Cosmos Hub, so it begins with the same ideas and then removes or replaces some components. Each change affects how the chain behaves, what developers can build, and how validators are rewarded or constrained.
In AtomOne's case, the removals are concrete. The Liquid Staking Module, Interchain Security, Packet Forwarding Middleware and the globalfee module are no longer part of the design. Fee logic returns to an older form, and the address prefix changes. Each of these choices reduces one set of features while keeping the rest of the Cosmos framework in place.
For a reader, the practical lesson is to compare the two chains directly. Check the source code differences, read the release notes for each version, and test on a non-production setup before relying on any behavior. A fork can look similar at first glance, yet small changes in governance or fees can have large effects.

Supported coins
The documentation associates the AtomOne node with Cosmos (ATOM), the coin of the Cosmos Hub that AtomOne is forked from. Ledger hardware wallets are listed among the supported hardware wallets for this ecosystem. The program also lists the SHA-256 algorithm, but the node is blockchain client software rather than a mining program, so it is not used for mining in the usual sense.
How to install AtomOne node on Windows
- 1
Open the Official Source
Go to the project's GitHub repository at github.com/atomone-hub/atomone and open the Releases page. Download only from the official website or the official GitHub Releases page, and avoid mirrors or links shared in chats or forums. Official sources reduce the risk of getting a modified file.
- 2
Choose the Right Release
The latest tagged version is v4.2.0-rc.2, which is a release candidate rather than a final release. Look for the Windows build or installer in the release assets. Read the release notes before you install, so you know which changes are included.
- 3
Verify the File
Compare the SHA-256 checksum of the downloaded file with the value published on the release page. If the project provides a signature, verify that as well. Do not run a file whose checksum does not match, even if it came from a link that looks official.
-
Install and Test the Program
Run the installer, or extract the build to a folder you control. Open a terminal in that location and launch atomoned to confirm that it starts correctly. Keep the install in a dedicated folder so that updates and backups are easier to manage.
How to use AtomOne node
Using the AtomOne node means preparing a local home directory, adjusting a few configuration files and letting the daemon sync with the network. The steps below follow the usual Cosmos SDK workflow, so anyone familiar with Cosmos chains will find them recognizable. Beginners should go slowly and check each output before moving to the next step.
- Create the node home directory using the init command and choose a clear node name. Keep a note of the directory path, because the configuration and data files live there.
- Open the configuration files in the home directory and review the RPC, peer and logging settings. Change only what you understand, and keep a backup of the original files.
- Start atomoned from a terminal window and leave it running. The first sync can take a long time, depending on network speed and disk performance.
- Check the sync status through the local RPC endpoint. When the node reports that it has caught up, you can use it for queries and development work.
Keep the terminal open or run the daemon as a service if you need it to stay online. Monitor disk space, because blockchain data grows over time. If the node stops, read the log output first, since most startup problems show up there.
Pros & cons
- Free and open source, with the code published on GitHub
- Built on the Cosmos SDK, so Cosmos developers will find the structure familiar
- Documented differences from Cosmos Hub make it clear what has changed
- Windows build or installer is available
- Custom atone address prefix helps separate addresses from Cosmos Hub
- Removes some modules, which narrows the surface to review
- The current version is a release candidate, not a final release
- Behavior differs from Cosmos Hub, so it is not a drop-in replacement
- Running a full node needs ongoing disk space and monitoring
- Governance voting rules for validators differ from the upstream hub
- Users coming from Cosmos Hub need to learn the changes before operating it
Is AtomOne node safe?
Download AtomOne node only from the official GitHub repository or its Releases page. Before running the file, compare its SHA-256 checksum with the value published by the project, or verify a signature if one is provided. A mismatch means you should not run the file. A node may hold validator keys, so never enter a seed phrase or private key on third-party websites, in chats or in support requests. Because the current version is a release candidate, expect bugs and check the latest version on the official website before using it for anything important.
- Official source only. Download from github.com/atomone-hub/atomone. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
AtomOne is closest to Cosmos Hub, since it is a fork of that chain. Running Gaia, the Cosmos Hub node, gives you the upstream behavior, including Liquid Staking Module support, Interchain Security and the standard globalfee logic. AtomOne removes those parts and changes the address prefix, so it is a separate network rather than a simple alternative client.
Other entries in this catalog, such as Evmos, Celestia App and Aptos, serve different networks with their own design goals. Geth and OpenEthereum belong to the Ethereum ecosystem, while Bitcoin Core serves the Bitcoin network. If your goal is the AtomOne chain specifically, AtomOne node is the relevant choice; for other networks, pick the client that matches that chain.

Frequently asked questions
It can be, if you take the right precautions. Download the file only from the official GitHub Releases page, compare the SHA-256 checksum with the published value, and avoid links shared by strangers. Because the current version is a release candidate, expect that it may change before a final release.
Atomoned is the name of the daemon that runs the AtomOne node. It connects your computer to the AtomOne network, stores chain data and validates blocks. You start it from a terminal, and it runs until you stop it.
No, the program is free. The code is open source and published on GitHub. Running a node does have ongoing costs in hardware, storage and internet connection, but the software itself carries no price.
AtomOne is a fork of the Cosmos Hub that removes several modules, including the Liquid Staking Module, Interchain Security and Packet Forwarding Middleware. It also changes the fee logic, the Bech32 address prefix and the governance voting rules for validators. These changes make it a separate network.
The documentation associates the node with Cosmos (ATOM). AtomOne is built on the Cosmos ecosystem, so the coin and network context come from that framework. Check the official documentation for the latest details about the network.
Ledger hardware wallets are listed among the supported hardware wallets for this ecosystem. A hardware wallet keeps the private key on the device, which reduces the risk of key theft from your computer. Always confirm transactions on the device screen before approving them.
The atone prefix is the Bech32 prefix that AtomOne uses for addresses. It is defined in the configuration code and makes AtomOne addresses look different from Cosmos Hub addresses. The different prefix helps you recognize which network an address belongs to.
Verdict
AtomOne node is a good fit for developers, validators and technically confident users who want to run a node for the AtomOne network. It is free, open source and available as a Windows build or installer. The program suits people who already understand Cosmos-style chains or are willing to learn the differences from Cosmos Hub. Beginners who only want to use a wallet or check balances will not need it.
