No blockchain no, but does use private public key pairs, your data is stored on various relays, and you can run your own relay if you want There are other clients you can try if you're into long form content, like Habla, Highligher, blogstack or yakihonne Here's a post I did on nostr for bloggers https://thebitcoinmanual.com/articles/nostr-blogging/

Depends on what you mean, clients like apps on app stores and websites can be taken down sure, but you could run a client on your device, instead if you couldn't access a website or app The relays storing the posts, if governments go after companies running relays they might be able to take the content down or asking them to blacklist certain relays, but the content will still be available somewhere on another relay to be accessed So you can always take your account and content to another client, if you were removed from a certain front end/client

Pretty great. News NewsBreak was pretty free, but now they’ve banned anonymous email for registration. They always censored, but it always took a while and you could just set up a new account…no longer. We need a blockchain version of NewsBreak. Do that and we’ll have a revolution.

Why do you feel there needs to be a blockchain involved? Blockchains are not censorship resistant by default, who will be securing it, whats their economic incentive to secure the chain, who is going to deploy resources to validate the chain? Blockchains are awful data management tools

It's a hard problem to solve, nostr solves it by redundancy, if one relay censors you, your content can exist and be pulled from another, if all public relays censor you, you can run your own relay and no one can take down that instance of your content
