# Nostr: a quick introduction, attempt #2

Nostr doesn't subscribe to any ideals of "free speech" as these belong to the realm of politics and assume a big powerful government that enforces a common ruleupon everybody else.

Nostr instead is much simpler, it simply says that servers are private property and establishes a generalized framework for people to connect to all these servers, creating a true free market in the process. In other words, Nostr is the public road that each market participant can use to build their own store or visit others and use their services.

(Of course a road is never truly public, in normal cases it's ran by the government, in this case it relies upon the previous existence of the internet with all its quirks and chaos plus a hand of government control, but none of that matters for this explanation).

More concretely speaking, Nostr is just a set of definitions of the formats of the data that can be passed between participants and their expected order, i.e. messages between _clients_ (i.e. the program that runs on a user computer) and _relays_ (i.e. the program that runs on a publicly accessible computer, a "server", generally with a domain-name associated) over a type of TCP connection (WebSocket) with cryptographic signatures. This is what is called a "protocol" in this context, and upon that simple base multiple kinds of sub-protocols can be added, like a protocol for "public-square style microblogging", "semi-closed group chat" or, I don't know, "recipe sharing and feedback".
 

 “Nostr instead is much simpler, it simply says that servers are private property” (cf. fiatjaf). Not necessarily; there are also institutional and community servers (run by universities, schools, churches, LGBT groups, etc.) that can run a #nostr relay at the service of that community and the common good. The #nostr does not have to be seen from a neo-capitalist point of view. The #nostr protocol is also compatible with a socialist or Marxist society. 

 Se o dono daquele servidor assim o quiser, visto que é uma propriedade privada. 

 Mas um determinado servidor pode ser propriedade de uma comunidade e não de um sujeito individual. 

 the first 2 paragraphs are ok, the last 2 are very confusing.
