Nostr is... compared to Mastodon/Fediverse, geared towards a different "threat model":
- Not federated
- it's up to you to post the same content to multiple relays, or not
- Your key is your account
- can't go down with an instance/relay
- if you lose it, then you lost it
- All messages are signed with your key
- an instance/relay operator can't supplant you
- If you get banned on a relay, you can use any other relay that isn't banning you, still with the same account (key)
- harder to censor an account
- harder to moderate
- easier to "migrate" from one server to another
- People who want to follow you, need to know your key and what relay(s) you post to
- harder to discover people
- Has a "like" system based on BTC micropayments
- harder to game with bots, since each "like" costs actual money
- more attractive to cryptobros
if my password get compromised, is there a way for my account to not be completely wiped out?
Your key is your account, anyone with access to your private key has full and unstoppable access to your account. AFAIK, there is no "key revocation" mechanism.
