What is the Context of Liveness Guarantees?

News concerning liveness guarantees often arises in discussions about the reliability and uptime of blockchain networks, particularly during periods of high load or network stress. Reports may analyze how different consensus mechanisms ensure continued operation or investigate instances where network liveness was compromised. Verifying these guarantees is fundamental to assessing the dependability of digital asset infrastructure.

Liveness Guarantees

Definition

Liveness guarantees ensure that a system or network will continue to operate and eventually make progress. This means that legitimate operations will not be indefinitely blocked or stalled. For decentralized systems, this assurance is critical for predictable performance and user confidence.
