Namecoin

Namecoin is a peer-to-peer generic name/value datastore system based on Bitcoin technology.

Allows you to:
* Securely register and transfer arbitrary names (keys), no possible censorship!
* Attach values (data) to the names (up to 520 bytes).
* Trade and transact namecoins, the digital currency NMC.

Use case examples:
[Name] => [Value]
DNS: domain_name => domain_zone_configuration
Identity: user_name => user_public_identity (email, name, gpg key, etc)
Timestamping: document_hash => document_infos (name, hash, owner, etc)

Main features:
* Distributed/decentralized: each user has its own copy of the full database.
* Secure: security (with public/private keys) is deeply integrated in the software to allow only the owner of a name to modify it in the distributed database.
* Pseudonymous: all transfers of data are public and linked to random generated addresses.
* Open: anybody can use namecoin to register a name or to create its own namespace.
