Pros[editovat]
- It can guarantee uniqueness of names
- Network can operate autonomously with manual policy
- It is independent to a government policy
Cons[editovat]
- 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 paid
- 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.
Additional root namespace[editovat]
To allow to have multiple root domains, new root namespace identifier have to be introduced to URL format.
