Compared to Bitcoin, Nostr has no single chain of blocks to represent a global state.
Our "nodes" don't pick the longest chain and censor every other alternative.
There are no miners to pick which posts are allowed to go into the chain.
There is no proof of work to create space in the chain.
There is no single core codebase to control any changes to the protocol.
There is just freedom.
The most raw encoding of freedom one can have.
