The decentralized design of this protocol introduces inherent challenges, especially in terms of data persistence and scalability. As no central authority stores the full message history, users frequently enough rely on third-party relays to access and store messages. This reliance raises concerns about data availability and censorship resistance, as some relays might restrict or selectively filter content based on their policies.

Moreover, the protocol’s simplicity, while beneficial for extensibility, means it currently lacks built-in support for complex features such as end-to-end encryption and identity verification beyond public key cryptography. As a result, privacy protections are limited, and users must exercise caution when sharing sensitive facts.

  • Data permanence: Message storage depends on external relays, risking data loss.
  • Censorship vulnerability: Selective content filtering by relays can occur.
  • Privacy constraints: Absence of native end-to-end encryption.
  • Scalability concerns: Message dissemination can face latency issues on busy networks.
