Definition ∞ The protection of information regarding whether a specific network participant is currently online or actively performing operations. This aspect of privacy aims to obscure the real-time presence and activity patterns of users or nodes within a decentralized system. It helps prevent surveillance or targeted attacks based on observed network engagement. Maintaining this privacy is essential for user security and network resilience.
Context ∞ Liveness privacy is a growing concern in decentralized networks, especially as transaction monitoring tools become more sophisticated. Discussions often focus on cryptographic techniques and network protocols designed to mask activity. Future research and development aim to enhance these privacy measures without compromising network liveness or consensus integrity.
