Definition ∞ A network health signal is an indicator that reflects the operational status, stability, and security of a blockchain network. These signals include metrics like hash rate, node count, transaction finality rates, and decentralization levels. A strong signal suggests a robust and secure network capable of processing transactions reliably. Conversely, weak signals can indicate potential vulnerabilities or performance issues. They are vital for assessing a network’s integrity.
Context ∞ Crypto news often references network health signals when discussing the security and resilience of various blockchain protocols. For example, a declining hash rate in a proof-of-work network might signal reduced security against 51% attacks. Monitoring these indicators provides critical insights into the underlying infrastructure, influencing investor confidence and the perceived reliability of digital assets.
