Decentralized DNS

Goals

• Allow decentralized functioning
• Prevent control by government
• Avoid cost of domain ownership
• Use existed technology if possible

DNS parts

• Maintaining global unique names (registration, holding, release)
• Name to IP address translation
• Identification of owner

Possible solutions

Alternative roots

• Wikipedia Alternative DNS root

Wob of Trust(WoT)

• WoT-DNS - Web of Trust based Domain Name System

Crypto-currency based

Notable example is Namecoin which is based on Bitcoin.

Pros

• It can guarantee uniqueness of names
• Network can operate autonomously with manual policy
• It is independent to a government policy

Cons

• Squatters can occupy general important names
• Network protocol is complicated and relies on cryptographic keys which can be broken on overpowered in future
• Domain name registration and renewal need to be payed
• Block chain size is ever growing with keeping old also false records.
• Network is vulnerable by 51% attack
• If private key and domain names are stolen then they can't be retrieved back without negotiation with thief.
• If private key is lost then domain will expire and can be registered by other entity.
