#187 Compare This branch is even with domob1812:master.
domob1812 Disable invalid tests from
Some of the tests in are not valid in Namecoin, because
they either run into the BDB lock limit or because they test strict
enforcement of BIP30, which is not active in Namecoin at all.

This disables (removes) those tests to make pass again
after a recent upstream change that made the checks stricter.

Namecoin Core integration/staging tree

Build Status

What is Namecoin?

Namecoin is a decentralized open source information registration and transfer system based on the Bitcoin cryptocurrency.

What does it do?

  • Securely record and transfer arbitrary names (keys).
  • Attach a value (data) to the names (up to 520 bytes, more in the future).
  • Transact namecoins, the digital currency (ℕ, NMC).

Namecoin was the first fork of Bitcoin and still is one of the most innovative altcoins. It was first to implement merged mining and a decentralized DNS. Namecoin squares Zooko's Triangle!

What can it be used for?

  • Protect free-speech rights online by making the web more resistant to censorship.
  • Access websites using the .bit domain (with TLS/SSL).
  • Store identity information such as email, GPG key, BTC address, TLS fingerprints, Bitmessage address, etc.
  • Human readable Tor .onion names/domains.
  • File signatures, Voting, bonds/stocks,/shares, web of trust, escrow and notary services (to be implemented).

For more information, as well as an immediately useable, binary version of the Namecoin Core software, see Public binary downloads are not yet posted.


Namecoin Core is released under the terms of the MIT license. See COPYING for more information or see

Development Process

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Namecoin Core.

The contribution workflow is described in

The developer forum should be used to discuss complicated or controversial changes before working on a patch set.

Developer IRC can be found on Freenode at #namecoin-dev.


Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/

There are also regression and integration tests, written in Python, that are run automatically on the build server. These tests can be run (if the test dependencies are installed) with: test/functional/

The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.


Translation workflow is not yet set up for Namecoin Core. For strings which are common to Bitcoin Core, see below.

Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.

Translators should also subscribe to the mailing list.
