Namecoin Core Wallet (v. 0.21.0, name registration via console only)

Namecoin Core wallet


The Namecoin Core wallet is based on Bitcoin's Core wallet, which got complemented by the Namecoin operations, originally just around 400 additional lines of code. The Core wallet itself is built on top of the Qt-Framework. This is why the Core versions are alternatively also called Bitcoin Qt and Namecoin Qt. The Core wallet contains Namecoin's complete codebase and needs the blockchain to be downloaded, which is about 5.8 GB for the full blockchain in 2021, for the source code see the GitHub repository.
When the Core wallet is started, it tries to connect to the Namecoin peer-to-peer network. Therefore it connects to five hard-coded DNS seed servers that provide the IP addresses of the actual peers. The seed servers are run by voluntaries:


Server Operator

seed.namecoin.libreisp.se

Jonas Ostman

nmc.seed.quisquis.de

Peter Conrad

seed.nmc.markasoftware.com

Mark Polyakov

dnsseed1.nmc.dotbit.zone

Stefan Stere

dnsseed2.nmc.dotbit.zone

Stefan Stere

In case the connection to other peers fails, the Core wallet tries to connect to a list of hard-coded peers. Sometimes even this backup procedure fails and it becomes necessary to add the first peer manually over the implemented command line interface. You may try to add the merged mining node bitcoins.sk with the command:

addnode "46.229.238.187:8334" add

To get more peers, you can manually request the seed servers above, e.g. on Windows using the command line interface (CMD console):

nslookup dnsseed1.nmc.dotbit.zone

All peers have to be connected via their port 8334. Alternatively, you may visit our Telegram group or our Discord community for getting actual peers.


Namecoin Electrum wallet

Namecoin Electrum wallet


The Electrum Client is a lightweight wallet and connects to an Electrum server from a hard-coded list of full nodes in the Namecoin Electrum peer-to-peer network, so no download of the blockchain is required. Electrum servers, on the other hand, require the entire blockchain to be downloaded, source code see the GitHub repository.


Upgrades, Backup & Restore


Updating your software wallet shouldn't affect your wallet. Also, it is no problem to import your wallet e.g. from one Core version to the other, e.g. from your desktop PC to your laptop. Just copy the wallet.dat file from the data path, e.g. on Windows under C:\Users\USERNAME\AppData\Roaming\Namecoin. Note, however, that you cannot use your wallet in multiple instances! Once you have made a transaction on the blockchain, this wallet will be the current one.

For the case that your wallet got corrupted and transactions are missing, e.g. after a hardware failure or a corrupted and restored operation system, you can restore your wallet to the current state on the blockchain with the following commands, e.g. on Windows in the CMD console:

cd C:\Program Files\Namecoin
namecoin-qt -salvagewallet

After the completion of the full indexing, the entire blockchain needs to be scanned again. Therefore, shutdown the wallet and restart with the following commands:

cd C:\Program Files\Namecoin
namecoin-qt -rescan

Please note that this emergency procedure takes several hours! To avoid data corruption and financial losses, make sure to back up the wallet.dat file regularly to a secure offline medium, especially before upgrading or changing the start sequence! The disclaimer from the following section applies:
