What is the Problem?
In today’s Internet, when you request any website by name – say, google.com – your browser asks central name-servers for how to reach that website.
These servers, called root servers, are operated by the same entity, usually a governmental organization. This system is prone to censorship, commercial takeover, tracking, data retention and other abuse.
Visitors can be misdirected. Owners can lose their websites.
Blockchain – the same mechanism used in Bitcoin – removes the need for a central entity. Instead, there is a network of independent nodes, each with full knowledge on all existing websites.
This kind of access cannot be tampered with. It can be only turned off – together with the Internet.
