Namecoin Core is the full node and wallet software for Namecoin, a cryptocurrency that also lets you register and manage names such as .bit domains. It is aimed at people who want to run their own copy of the network instead of trusting a third-party service, including developers, privacy-minded readers and anyone curious about decentralized naming. The program is free, open source under the MIT license, and available for Windows as a build or installer.
Running Namecoin Core lets you hold NMC, send transactions and resolve .bit domains through your own node. The current release is nc32.0, and the code was last updated on October 26, 2026, so the project is actively maintained. Read on for the feature set, installation steps, a safety checklist and a comparison with other full-node wallets.
What Is Namecoin and Why Its Names Matter
Namecoin is a cryptocurrency built around a different idea than most coins. Alongside its digital currency, NMC, the network records names: short keys that point to values, such as the address of a website or a block of contact details. The system is designed so that no single company or registry controls who holds a name.
That design is why the .bit top-level domain exists. Instead of relying on a central authority to assign domain names, .bit entries are stored on the Namecoin blockchain and read by software that follows the network's rules. Namecoin Core is the main software for doing that. It checks the chain and lets you register, transfer and update names.
The concept is easier to grasp when you compare it with the ordinary domain system. A conventional domain depends on a registrar that can suspend it. A name on Namecoin depends on the network's consensus, so changing it requires the holder's key rather than a request to an intermediary. The trade-off is that you carry more responsibility for your keys.
Who Namecoin Core Is For
Namecoin Core fits three kinds of users. The first is someone who wants to run a full node rather than rely on a remote server to report their balance or resolve a name. A full node checks transactions against the rules itself, so you are not taking someone else's word for the result.
The second group is developers and hobbyists building services on top of decentralized names. Because the software stores arbitrary key-value data, it is useful for testing how names, values and transfers behave before you build something around them. The third group is privacy-minded readers who care about censorship resistance and want a way to reach .bit sites without a registrar in the middle.
Casual users who only want to hold a small amount of NMC may find a lighter wallet simpler. A full node takes time to sync and keeps a copy of the chain on your disk. Namecoin Core rewards patience and a comfort level with technical tools.
Practical Scenarios for .bit Domains and Named Records
Consider a publisher who wants a website that cannot be taken down by a single registrar. They register a .bit name, point it at their site and store a TLS fingerprint in the name's value so visitors can confirm they reached the right server. Updates go through the same key, so the publisher keeps control of the record.
A second scenario is a small community that wants a human-readable name for a service. Instead of sharing a long address, members can use a name that resolves through the network. The name can also hold a contact email or a GPG key, so people can check who runs it.
A third use is linking a Tor onion service to a readable name. Hidden services have long address strings, and a readable name makes them easier to share and remember. Each scenario depends on careful key management, since whoever controls the key controls the name.
How a Full Node Keeps You Independent
A full node is a program that downloads and verifies the blockchain on your own computer. When it receives a transaction or a name update, it checks the result against the network rules rather than accepting a summary from someone else. That independence is the main reason people run one.
The process of catching up with the network is called syncing. During the first sync, the node downloads blocks in order and builds its local copy of the chain. Once synced, it stays current and can answer questions about balances and names without asking a remote server. Expect the first sync to be the slowest part of the experience.
Running a node also has a social side. Each node that stays online helps keep the network distributed, which is the foundation of its resistance to censorship. A node does not need to mine to be useful, though. Keeping it running and reachable is a valid contribution on its own.
Key features
Name registration and transfer
Attached values up to 520 bytes
NMC wallet functions
.bit domain access with TLS
Identity records
Readable Tor .onion names
Planned features on the roadmap
Supported coins
The software works with Namecoin (NMC), the network's own currency and naming layer. Its documentation also mentions Bitcoin (BTC), which appears in identity records as a Bitcoin address rather than as a separate wallet. Keep the two assets distinct in your mind: NMC lives on the Namecoin network, and BTC is referenced only as data that a name can store.
How to install Namecoin Core on Windows
- 1
Get the installer from the official source
Download only from the official website or the project's GitHub Releases page at github.com/namecoin/namecoin-core. Choose the Windows build or installer for the version you want, which is nc32.0 at the time of writing. Avoid mirrors, forum links and file-sharing sites.
- 2
Verify the file
Compare the SHA-256 checksum of the downloaded file with the value published on the release page. If a signature is provided, verify it as well. Do not run a file whose checksum does not match, and download it again from the source if in doubt.
- 3
Run the installer
Open the installer and follow the prompts. Choose an install folder and let the program create its data directory. Windows may show a security prompt for a downloaded program; that is not a reason to skip the checksum check you already completed.
-
Let the node synchronize
On first launch, the node connects to the network and downloads blockchain data. This can take a long time and needs free disk space and a stable connection. Leave the program open until it reports that it is up to date before you send or register anything.
How to use Namecoin Core
Namecoin Core works best when you treat the node as the foundation and the wallet as the tool on top of it. Once the program is running and synced, the basic workflow looks like this. Follow the steps in order and do not rush the first sync.
- Create or restore a wallet, then write the seed phrase on paper and store it offline.
- Wait for the node to finish syncing before sending or registering anything. The status area shows when the chain is current.
- Check your NMC balance in the wallet overview. Incoming payments appear as confirmations accumulate.
- To send coins, use the send function, paste the recipient address, enter the amount and review the fee before you confirm.
- To work with names, use the name tools to register or update an entry, and attach a value of up to 520 bytes.
- To visit a .bit site, point your browser or system resolver at your local node. The setup details change between releases, so check the current documentation, and confirm the TLS details before entering any personal information.
Pros & cons
- Free and open source under the MIT license, so the code can be reviewed by anyone
- Runs your own full node, so you do not rely on a third-party server to check the chain
- Combines NMC wallet functions with name registration and data storage
- Supports .bit domains and readable names for Tor .onion services
- Available for Windows, macOS and Linux, so the knowledge carries across systems
- The first sync can take a long time and needs steady disk space
- Several planned features, such as voting and escrow, are not yet working
- Attached values are capped at 520 bytes for now
- Requires more technical comfort than a simple mobile wallet
Is Namecoin Core safe?
Treat Namecoin Core like any wallet that handles real money. Download the Windows build or installer only from the official website or the project's GitHub Releases page, never from a mirror, a forum link or a file-sharing site. Before you run it, compare the SHA-256 checksum of the file with the value published on the release page, and verify a signature if one is available. A mismatch means you should not run the file.
Never type your seed phrase or private keys into a third-party website, app or support chat, even one that claims to be helping you. Anyone who has those words can take your coins and names. Write the seed phrase on paper, store it offline and keep a second copy in a separate safe place. Check the latest version on the official website before updating.
- Official source only. Download from github.com/namecoin/namecoin-core. 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
Namecoin Core shares its basic shape with other full-node wallets in this catalog. Dogecoin Core, Litecoin Core, Qtum Core, Syscoin Core, Komodo Core, KatKoyn Core and Bitcoin Gold each provide a node and wallet for their own networks. If your goal is to hold and move those coins, one of them is the right tool, and Namecoin Core is not a substitute.
What sets Namecoin Core apart is the naming layer. Its node and wallet are built around registering names and attaching data to them, including .bit domains. Monero CLI takes a different path: it is a command-line daemon and wallet for Monero, focused on private transactions rather than names. Choose the software that matches the network you actually use.

Frequently asked questions
Namecoin Core is the full node and wallet for the Namecoin network. It lets you hold and send NMC, register and manage names such as .bit domains, and verify the blockchain yourself rather than trusting a remote server. Most people run it to stay independent of third-party services.
Yes. Namecoin Core is free and released under the MIT license, which means its source code is open for anyone to read, use and modify. The software itself has no paid tier, though transactions on the network carry fees paid in NMC.
It can be, provided you download it from the project's GitHub Releases page or official website and check the SHA-256 checksum before running it. Keep Windows security protection turned on, and never type your seed phrase into a third-party site. The safety section explains each step in more detail.
Start the node, let it finish syncing, then point your browser or system resolver at the local node so that .bit names resolve. The exact setup depends on your configuration, so check the current documentation. Once it works, .bit sites load much like other websites, using TLS where the site provides it.
Keeping the node running is best, because it stays synced and can answer name lookups from your own copy of the chain. If you close it, the node falls behind until you reopen it and catch up. Wallet balances update once the node is current again.
A .bit domain is a name registered on the Namecoin network instead of through a traditional registrar. Its records are stored on the blockchain, and the holder controls them with a key. Because no single company can revoke the name, .bit domains are often discussed in the context of censorship resistance.
Yes. The software supports human-readable names for Tor .onion services, so you can refer to a hidden service with a readable name. Tor is a separate tool, so you still need it set up on your computer to reach the .onion address behind the name.
Verdict
Namecoin Core is the right choice if you want to run your own node for NMC and work with .bit domains and decentralized names. It rewards patience during the first sync and some technical comfort, and it is not designed to be a quick mobile wallet. If you mainly hold Dogecoin, Litecoin or another coin from this catalog, the matching Core wallet fits better. Verify the Windows build before you run it, and back up your seed phrase before you rely on the wallet for anything important.
