Centralized platforms own the identity layer. When two firms control the social graph for most U.S. internet users, a ban does not restrict speech, it deletes the audience a creator spent years building.

Nostr inverts the arrangement. Identity is a keypair the user generates; relays store and forward signed events without holding authority over the account. Exit becomes possible without losing followers or history. Long-form articles, marketplaces, and encrypted messages ride the same format.
