Nostr (Notes and Other Stuff Transmitted by Relays) is a decentralized, open protocol for social networking, which offers better privacy than centralized platforms like X (Twitter). But there are still some privacy concerns.
Metadata Exposure
Even if messages are encrypted, metadata (timestamps, IP addresses) can be tracked, which reveals user behavior patterns.
Relay Trust
Users must trust relays not to log or misuse data. A rogue relay could log or track user data.
Default Encryption
Nostr supports end-to-end encryption, but it may not be enabled by default. This risks message interception by relays.
Public Keys Exposure
Public keys are visible and this allows tracking of user activity across relays and over time, which compromises anonymity.
Replay Attacks
Without proper timestamping, messages can be replayed by attackers. This can cause misinformation or identity spoofing.
User Behavior Analysis
Posting frequency, interaction patterns and network activity can still be analyzed, which can be used to profile users despite decentralization.
My best advice:
Use a VPN or Tor to hide your IP.
Choose trusted relays like https://pmnr.xmr.rocks/
Maybe avoid posting at regular intervals or revealing your location through content.
Be cautious with personal information (as always).
Use secure devices to access Nostr.
Stay informed.
