Namecoin is an experimental open-source technology which improves decentralization, security, censorship resistance, privacy, and speed of certain components of the Internet infrastructure such as DNS and identities.

(For the technically minded, Namecoin is a key/value pair registration and transfer system based on the Bitcoin technology.)

Bitcoin frees money – Namecoin frees DNS, identities, and other technologies.

What can Namecoin be used for?

  • Protect free-speech rights online by making the web more resistant to censorship.
  • Attach identity information such as GPG and OTR keys and email, Bitcoin, and Bitmessage addresses to an identity of your choice.
  • Human-meaningful Tor .onion domains.
  • Decentralized TLS (HTTPS) certificate validation, backed by blockchain consensus.
  • Access websites using the .bit top-level domain.
  • Proposed ideas such as file signatures, voting, bonds/stocks/shares, web of trust, notary services, and proof of existence. (To be implemented.)

What does Namecoin do under the hood?

  • Securely record and transfer arbitrary names (keys).
  • Attach a value (data) to the names (up to 520 bytes).
  • Transact the digital currency namecoins (NMC).
  • Like bitcoins, Namecoin names are difficult to censor or seize.
  • Lookups do not generate network traffic (improves privacy).

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 was also the first solution to Zooko’s Triangle, the long-standing problem of producing a naming system that is simultaneously secure, decentralized, and human-meaningful.

2017-06-22 The aforementioned licensing issues with TorNS have been dealt with, and I’ve released the DNS provider for Tor’s Prop279 Pluggable Naming API. This allows Namecoin resolution in Tor.

2017-06-21 A while back, I released on the tor-dev mailing list a tool for using Namecoin naming with Tor. It worked, but it was clearly a proof of concept. For example, it didn’t implement most of the Namecoin domain names spec, it didn’t work with the libdohj client, and it used the Tor controller API. I’ve now coded a new tool that fixes these issues.

2017-06-20 As I mentioned in my previous post, we protect from compromised CA’s by using a nothing-up-my-sleeve (NUMS) HPKP pin in Chromium. Previously, it was necessary for the user to add this pin themselves in the Chromium UI. This was really sketchy from both a security and UX point of view. I have now submitted a PR to ncdns that will automatically add the necessary pin.

2017-06-17 Work on the electrum port for Namecoin has been moving along nicely. It was decided that we will use the electrum-client from spesmilo, along with the electrumX server. ElectrumX was chosen due to the original electrum-server being discontinued a few months ago. So far the electrum client has been ported over for compatability with electrumX. This includes the re-branding, blockchain parameters and other electrum related settings for blockchain verification

2017-06-15 Back in the “bad old days” of Namecoin TLS (circa 2013), we used the Convergence codebase by Moxie Marlinspike to integrate with TLS implementations. However, we weren’t happy with that approach, and have abandoned it in favor of a new approach: dehydrated certificates.

2017-05-30 In order to facilitate the easy resolution of .bit domains, an installer for ncdns for Windows has been under development. This installer automatically installs and configures Namecoin Core, Unbound and ncdns.

2017-05-27 Every so often, I’m doing Namecoin-related development research (in this case, making TLS work properly) and I run across some really interesting information that no one else seems to have documented. While this post isn’t solely Namecoin-related (it’s probably useful to anyone curious about tinkering with TLS), I hope you find it interesting regardless.

2017-05-19 We’re happy to announce that Namecoin is receiving 29,895 EUR in funding from NLnet Foundation’s Internet Hardening Fund. If you’re unfamiliar with NLnet, you might want to read about NLnet Foundation, or just take a look at the projects they’ve funded over the years (you might see some familiar names). The Internet Hardening Fund is managed by NLnet and funded by the Netherlands Ministry of Economic Affairs. The funding will be used to fund 4 Namecoin developers (Jeremy Rand, Hugo Landau, Brandon Roberts, and Joseph Bisch) to produce a usable decentralized TLS public key infrastructure.
