defy.social is a NOSTR based social networking client that only posts notes into encrypted events.
Each defy.social note is encrypted with a unique key and signed by another unique key leaving no trace of the original content or author in the underlying NOSTR event.
Each note is posted with a tag that identifies what channel the note is to appear. Without the correct collection of keys, users will be unable to find and read your notes.
Some channel owners make their keys readable by the public. Public channels are used to find like minded users that they be invited to private channels. Public channels also serve as a great tool for demonstrating how defy.social channels work without needing to become invited to a private channel.
The overwhelming majority of channels on defy.social are private and you will not know of their existence without someone inviting you to join them.
