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.)
