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.

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.

Binary Encoding Support and Testing Enhancements

2023-12-04 Electrum-NMC has recently undergone significant improvements aimed at refining the user experience and expanding functionality. The most prominent changes involve the introduction of three distinct tabs within the graphical user interface (GUI): Hex, Domain, and ASCII. The Hex tab now serves as a dedicated space for users to interact with the hexadecimal representations of names, providing a standardized and transparent view of binary data. The Domain tab focuses on simplifying interactions by allowing users to employ a simpler format like “name.bit” instead of the original “d/name” format. Meanwhile, the ASCII tab preserves the original format of registration, ensuring compatibility for users who prefer the original format.

SOCKSification: Outreachy Internship Progress

2023-02-23 SOCKSification refers to the process of rerouting network traffic from an application via a SOCKS proxy server. This method is frequently used for security, anonymity, and circumventing network constraints. There are numerous techniques for SOCKSification, but in this article, we will focus on two main approaches that were considered.

Outreachy Internship Progress

2023-01-29 Greetings! I wanted to provide an overall update on the project’s progress. We have successfully implemented the ability to detect the IP address and port that socket system calls are sending data to, as well as the capability to block system calls that are sending data to an IP address and port that is not the desired proxy. Additionally, we have added an option to kill the application if a proxy leak occurs, which is useful for manual QA testing, and an option to allow proxy leaks but log any that occur, which is useful for automated testing of applications. Furthermore, we have included the capability to use the environment variables that Tor Browser uses, such as TOR_SOCKS_PORT, to determine the desired proxy.

Internship Progress

2023-01-10 Greetings! I completed the initial tasks for the internship during the first week, where I utilized and experimented with the u-root strace package. The first tasks were to launch a program using ptrace and detect socket system calls. The first task was straightforward, requiring only the usage of the Trace Function. For the latter, it included utilizing a map to determine if the system call is a socket syscall and then informing the user if it is.
