Namecoin
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.
- Human-meaningful Tor .onion domains.
- Decentralized TLS (HTTPS) certificate validation, backed by blockchain consensus.
- Access websites using the .bit top-level domain.
- Attach identity information such as GPG and OTR keys and email, Bitcoin, and Bitmessage addresses to an identity of your choice.
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.

Enhancing Proxy Leak Detection with SocksTrace: From ptrace to seccomp notify

38C3 Summary
2025-03-30 As was previously announced, several developers represented Namecoin at 38C3 in Leipzig, Germany. You know the drill by now: we had a lot of conversations with other attendees, and we won’t be publicly disclosing the content of those conversations, because I want people to be able to talk to us at conferences without worrying that off-the-cuff comments will be broadcast to the public. That said, a practical result of one of those conversations should be getting its own announcement in the next day or two.

Tor Meeting 2024 / GPN 22 / MoneroKon 4 Summary (UPDATED)
2024-07-24 As was previously announced, Rose, yanmaani, Hugo, and I (Jeremy Rand) represented Namecoin at three conferences in Europe. This was an excellent series of events for a number of reasons, not least the fact that this is the first time we’ve ever had 4 Namecoin developers attending a single conference (our previous record was 3 developers, at 37C3). Expanding our team size has been a priority for a while, and it’s great to see that this is starting to pay off. Of course, there were major substantive benefits as well. As usual for conferences that Namecoiners attend, we engaged in a large number of conversations with other attendees. Also as usual, we won’t be publicly disclosing the content of those conversations, because I want people to be able to talk to us at conferences without worrying that off-the-cuff comments will be broadcast to the public.
